Fracking - energy revolution or skillfully marketed mirage? [27Jun11] - 0 views

  • The New York Times published an article on Sunday, June 26, 2011 titled Insiders Sound an Alarm Amid a Natural Gas Rush. The article quotes a number of emails from natural gas industry insiders, financial analysts that cover the gas industry and skeptical geologists to produce a number of questions about the long term viability of an increasing dependence on cheap natural gas from hydraulic fracturing. The message is that the gas industry has been engaging in hyperbole regarding its capacity to expand production at current prices to meet market demands.
  • the people quoted in the NY Times article do not agree that the technique magically produces low cost gas in unprecedented abundance.
  • “Our engineers here project these wells out to 20-30 years of production and in my mind that has yet to be proven as viable,” wrote a geologist at Chesapeake in a March 17 e-mail to a federal energy analyst. “In fact I’m quite skeptical of it myself when you see the % decline in the first year of production.”

  • “In these shale gas plays no well is really economic right now,” the geologist said in a previous e-mail to the same official on March 16. “They are all losing a little money or only making a little bit of money.”
  • Around the same time the geologist sent the e-mail, Mr. McClendon, Chesapeake’s chief executive, told investors, “It’s time to get bullish on natural gas.”
  • Aubrey McClendon, whose name is not terribly familiar to people outside of the energy industry, has an enormous financial interest in encouraging customers to become addicted to natural gas so that they will keep buying even if the price shoots up – like it did in the period from 2000-2008. During that time McClendon and his company rode a wave that resulted in growing a company from tiny to huge based on debt-financed investments in leases and drilling rigs designed to produce gas in the midcontinent region of the US. A high portion of the company’s wells were stimulated with hydraulic fracturing.
  • When the price of natural gas collapsed in 2008, mostly as a result of the contraction in demand caused by the financial crisis and resulting economic recession/depression, McClendon nearly lost control of his company. He had to sell “substantially all” of shares at a dramatically lowered price in order to pay off creditors and meet margin calls.
  • No U.S. chief executive officer has bought more of his own company’s stock in recent years than McClendon, even as the shares reached all-time highs. His appetite for Chesapeake stock made him “a darling of Wall Street,” Tulsa money manager Jake Dollarhide said. But his purchases were made on margin, meaning he used borrowed money. As the value of the stock fell, McClendon was forced to raise cash to meet margin calls. Recent losses — Chesapeake shares have plummeted 60 percent in the past three weeks — left him unable to fulfill those requirements.Read more: http://newsok.com/market-slide-wipes-out-ceos-chesapeake-holdings/article/3310107#ixzz1QSst9NnL
  • McClendon responded vigorously to the NY Times’s suggestion that the gas revolution was more mirage than miracle in a lengthy letter to Chesapeake Energy employees that was published on the company’s public Facebook page. (Note: The timing of this letter with regard to the NY Times article is telling. The article appeared in the Sunday edition of the Times on June 26, 2011. The letter to employees included a time stamp indicating that it was released at 8:37 pm on the same day while the Facebook page indicates that it was posted to the world by 11:27 pm. In other words – there is no rest for the weary in the Internet era.)
  • McClendon’s letter blamed the NY Times article on environmental activists that proclaim a desire to supply all of the US energy needs from wind and solar energy. It also issued a call to action for Chesapeake Energy employees:
  • We hope that every Chesapeake employee can be part of our public education outreach. At more than 11,000 strong, we are an army of “factivists” – people who have knowledge of the facts and the personal knowledge and ability to spread them. You can do this by talking to your families, friends and others in your spheres of influence (schools, churches, civic organizations, etc) about the kind of company you work for and the integrity of what we do every day for our shareholders, our communities, our states, our nation, our economy and our environment. You don’t have to be an expert to stand up and tell folks that Chesapeake is committed to doing what’s right – and that commitment is expressed every day by you and your colleagues across the company.
  • You can also get involved by joining Chesapeake Fed PAC, our political action committee. Our opponents are extremely well funded and organized. We need to make sure our voice is heard in Washington, DC and with elected officials who are making decisions that affect our industry, our company and our ability to operate in the many states in which shale gas and oil have been discovered.
  • After describing how Chesapeake has 125 active drilling rigs and how it has developed a “swat team” with more than 100 employees that works with environmental groups to produce legislation designed to slow the development of new coal fired power plants and to hasten the closure of existing coal plants, Tom Price said the following:
  • “It’s been said before, but the demand side of the equation is extremely important right now. I mean this really is a zero sum game. I think that there are a number of very progressive utilities out there that recognize the challenges that they are facing with regard to climate change, but the Transport Rule, Clean Air Act and various others.”
  • I remain convinced that there is a market battle going on between natural gas and nuclear energy.

Did Fukushima kill the nuclear renaissance No, that renaissance died right here at home... - 0 views

shared by D'coda Dcoda on 04 Nov 11 - No Cached
  • In the aftermath of the Fukushima Daiichi nuclear disaster in Japan, many wondered what the event’s impact would be on the nuclear renaissance in the United States. Those who follow the nuclear industry didn’t need eight months of hindsight to give an answer: what nuclear renaissance? The outlook for U.S. nuclear power has worsened considerably in the past five years. Where once there were plans for new reactors at more than 30 different sites, today there are only five, and even those planned reactors might disappear. Only one is actually under construction, and to credit the industry with breaking ground on a new reactor is overstating its prospects. However, none of this gloom is the result of Japan’s tsunami. On the eve of the Tohoku earthquake, U.S. nuclear power looked just as moribund as it is today. The cause of this decline is not renewed concerns about safety, or even that old red herring, waste disposal — instead, it is simple economics. Other technologies, particularly natural gas, offer much cheaper power than nuclear both today and in the foreseeable future.
  • In 2009, the MIT Future of Nuclear Power study released an update to its 2003 estimate of the costs of nuclear power. Estimating a capital cost of $4,000/kW and a fuel cost of $0.67/MMBtu, the study’s authors projected a cost of new nuclear power of 6.6 cents/kWh. Using the same modeling approach, the cost of electricity from a natural gas plant with capital costs of $850/kW and fuel costs of $5.16/MMBtu would be 4.4 cents/kWh. What’s worse, the estimate of 6.6 cents/kWh assumes that nuclear power is able to secure financing at the same interest rate as natural gas plants. In reality, credit markets assign a significant risk premium to nuclear power, bringing its total levelized cost of electricity to 8.4 cents/kWh, nearly twice the cost of natural gas power. Unless the capital costs of new nuclear power plants turn out to be significantly less than what experts expect, or natural gas prices rise considerably in the near future, there is little reason to believe that any new nuclear plants will be built without significant subsidies. This is not to say that nuclear power could not make a comeback within the next 10 to 20 years. But before nuclear can once again be considered a credible competitor to fossil fuels, four changes must happen.
  • The second problem facing nuclear power is its high borrowing costs. To some extent, this problem is a natural consequence of nuclear power plants taking a longer time to build than natural gas plants and having a much higher construction risk (the capital cost of natural gas plants is well-established relative to that of nuclear power). And likewise, to some extent, this problem might resolve itself over time, both as the completion of nuclear plants helps nail down the true capital cost of nuclear power, and as vendors add smaller, modular reactor designs to their list of offerings. But much of the reason behind the high interest rates on loans to nuclear construction is that the industry is scoring an own-goal. In the current relationship between utilities and reactor vendors, utilities are asked to absorb all of the costs of a vendor’s overruns — if a reactor ends up costing a couple billion dollars more than the vendor quotes, it’s the utility that is expected to make up the difference.

  • This is terrifying for a utility’s creditors. The largest utilities in the United States have market capitalizations in the area of $30 billion, while most hover closer to $5 billion. If a nuclear project should fail, the utility might go completely bankrupt, leaving nothing to those foolish enough to lend them money. Accordingly, nuclear projects face higher borrowing costs than other electric projects. It doesn’t have to be this way — if reactor vendors and construction companies helped share the project risks posed by nuclear plants, borrowing costs would be lower. It is also possible for the U.S. government to shoulder some of the risk — but after Solyndra, few legislators have an appetite for letting energy companies push their risks onto the taxpayer.
  • Next, the United States is going to have to adopt some form of carbon tax on electricity generation, or offer a comparable subsidy to the nuclear industry. An appropriately sized carbon tax of $20/ton CO2 would raise the cost of natural-gas-generated electricity by 0.7 cents/kWh, while having a negligible impact on nuclear power
  • And finally, the nuclear industry is just going to have to catch some luck and see natural gas prices rise. That’s a tall order, given the new resources being opened up by hydraulic fracturing and the slowed consumption of natural gas brought about by the recession. But it’s not entirely outside of the realm of possibility — the futures market for natural gas has been wrong before.
  • Nuclear power is down, but not out. With a proper R&D focus, good business practices, appropriate policy, and a little luck, the gulf that separates nuclear power from its competitors may yet be bridged.

The Dispatch Queue - An Alternative Means of Accounting for External Costs? [28Sep11] - 0 views

  • Without much going on recently that hasn’t been covered by other blog posts, I’d like to explore a topic not specifically tied to nuclear power or to activities currently going on in Washington, D.C. It involves an idea I have about a possible alternative means of having the electricity market account for the public health and environmental costs of various energy sources, and encouraging the development and use of cleaner sources (including nuclear) without requiring legislation. Given the failure of Congress to take action on global warming, as well as environmental issues in general, non-legislative approaches to accomplishing environmental goals may be necessary. The Problem
  • One may say that the best response would be to significantly tighten pollution regulations, perhaps to the point where no sources have significant external costs. There are problems with this approach, however, above and beyond the fact that the energy industry has (and will?) successfully blocked the legislation that would be required. Significant tightening of regulations raises issues such as how expensive compliance will be, and whether or not viable alternative (cleaner) sources would be available. The beauty of simply placing a cost (or tax) on pollution that reflects its costs to public health and the environment is that those issues need not be addressed. The market just decides between sources based on the true, overall cost of each, resulting in the minimum overall (economic + environmental) cost-generation portfolio
  • The above reasoning is what led to policies like cap-and-trade or a CO2 emissions tax being proposed as a solution for the global warming problem. This has not flown politically, however. Policies that attempt to have external costs included in the market cost of energy have been labeled a “tax increase.” This is particularly true given that the associated pollution taxes (or emissions credit costs) would have largely gone to the government.
  • ...15 more annotations...
  • One final idea, which does not involve money going to or from government, is simply requiring that cleaner sources provide a certain fraction of our overall power generation. The many state Renewable Portfolio Standards (that do not include nuclear) and the Clean Energy Standard being considered by Congress and the Obama administration (which does include nuclear) are examples of this policy. While better than nothing, such policies are not ideal in that they are crude, and don’t involve a quantitative incentive based on real external costs. An energy source is either defined as “clean,” or it is not. Note that the definition of “clean” would be decided politically, as opposed to objectively based on tangible external costs determined by scientific studies (nuclear’s exclusion from state Renewable Portfolio Standards policies being one outrageous example). Finally, there is the fact that any such policy would require legislation.
  • Well, if we can’t tax pollution, how about encouraging the use of clean sources by giving them subsidies? This has proved to be more popular so far, but this idea has also recently run into trouble, given the current situation with the budget deficit and national debt. Events like the Solyndra bankruptcy have put government clean energy subsidies even more on the defensive. Thus, it seems that neither policies involving money flowing to the government nor policies involving money flowing from the government are politically viable at this point.
  • All of the above begs the question whether there is a policy available that will encourage the use of cleaner energy sources that is revenue-neutral (i.e., does not involve money flowing to or from the government), does not involve the outright (political) selection of certain energy sources over others, and does not require legislation. Enter the Dispatch Queue
  • There must be enough power plants in a given region to meet the maximum load (or demand) expected to occur. In fact, total generation capacity must exceed maximum demand by a specified “reserve margin,” to address the possibility of a plant going offline, or other possible considerations. Due to the fact that demand varies significantly with time, a significant fraction of the generation capacity remains offline, some or most of the time. The dispatch queue is a means by which utilities, or independent regional grid operators, decide which power plants will operate in order to meet demand at any given instant. A good discussion of dispatch queues and how they operate can be found in this Department of Energy report.
  • The general goal of the methodology used to set the dispatch queue order is to minimize overall generation cost, while staying in compliance with all federal or state laws (environmental rules, etc.). This is done by placing the power plants with the lowest “variable” cost first in the queue. Plants with the highest “variable” cost are placed last. The “variable” cost of a plant represents how much more it costs to operate the plant than it costs to leave it idle (i.e., it includes the fuel cost and maintenance costs that arise from operation, but does not include the plant capital cost, personnel costs, or any fixed maintenance costs). Thus, one starts with the least expensive plants, and moves up (in cost) until generation meets demand. The remaining, more expensive plants are not fired up. This ensures that the lowest-operating-cost set of plants is used to meet demand at any given time
  • As far as who makes the decisions is concerned, in many cases the local utility itself runs the dispatch for its own service territory. In most of the United States, however, there is a large regional grid (covering several utilities) that is operated by an Independent System Operator (ISO) or Regional Transmission Organization (RTO), and those organizations, which are independent of the utilities, set the dispatch queue for the region. The Idea
  • As discussed above, a plant’s place in the dispatch queue is based upon variable cost, with the lowest variable cost plants being first in the queue. As discussed in the DOE report, all the dispatch queues in the country base the dispatch order almost entirely on variable cost, with the only possible exceptions being issues related to maximizing grid reliability. What if the plant dispatch methodology were revised so that environmental costs were also considered? Ideally, the public health and environmental costs would be objectively and scientifically determined and cast in terms of an equivalent economic cost (as has been done in many scientific studies such as the ExternE study referenced earlier). The calculated external cost would be added to a plant’s variable cost, and its place in the dispatch queue would be adjusted accordingly. The net effect would be that dirtier plants would be run much less often, resulting in greatly reduced pollution.
  • This could have a huge impact in the United States, especially at the current time. Currently, natural gas prices are so low that the variable costs of combine-cycle natural gas plants are not much higher than those of coal plants, even without considering environmental impacts. Also, there is a large amount of natural gas generation capacity sitting idle.
  • More specifically, if dispatch queue ordering methods were revised to even place a small (economic) weight on environmental costs, there would be a large switch from coal to gas generation, with coal plants (especially the older, dirtier ones) moving to the back of the dispatch queue, and only running very rarely (at times of very high demand). The specific idea of putting gas plants ahead of coal plants in the dispatch queue is being discussed by others.
  • The beauty of this idea is that it does not involve any type of tax or government subsidy. It is revenue neutral. Also, depending on the specifics of how it’s implemented, it can be quantitative in nature, with environmental costs of various power plants being objectively weighed, as opposed certain sources simply being chosen, by government/political fiat, over others. It also may not require legislation (see below). Finally, dispatch queues and their policies and methods are a rather arcane subject and are generally below the political radar (many folks haven’t even heard of them). Thus, this approach may allow the nation’s environmental goals to be (quietly) met without causing a political uproar. It could allow policy makers to do the right thing without paying too high of a political cost.
  • Questions/Issues The DOE report does mention some examples of dispatch queue methods factoring in issues other than just the variable cost. It is fairly common for issues of grid reliability to be considered. Also, compliance with federal or state environmental requirements can have some impacts. Examples of such laws include limits on the hours of operation for certain polluting facilities, or state requirements that a “renewable” facility generate a certain amount of power over the year. The report also discusses the possibility of favoring more fuel efficient gas plants over less efficient ones in the queue, even if using the less efficient plants at that moment would have cost less, in order to save natural gas. Thus, the report does discuss deviations from the pure cost model, to consider things like environmental impact and resource conservation.
  • I could not ascertain from the DOE report, however, what legal authorities govern the entities that make the plant dispatch decisions (i.e., the ISOs and RTOs), and what types of action would be required in order to change the dispatch methodology (e.g., whether legislation would be required). The DOE report was a study that was called for by the Energy Policy Act of 2005, which implies that its conclusions would be considered in future congressional legislation. I could not tell from reading the report if the lowest cost (only) method of dispatch is actually enshrined somewhere in state or federal law. If so, the changes I’m proposing would require legislation, of course.
  • The DOE report states that in some regions the local utility runs the dispatch queue itself. In the case of the larger grids run by the ISOs and RTOs (which cover most of the country), the report implies that those entities are heavily influenced, if not governed, by the Federal Energy Regulatory Commission (FERC), which is part of the executive branch of the federal government. In the case of utility-run dispatch queues, it seems that nothing short of new regulations (on pollution limits, or direct guidance on dispatch queue ordering) would result in a change in dispatch policy. Whereas reducing cost and maximizing grid reliability would be directly in the utility’s interest, favoring cleaner generation sources in the queue would not, unless it is driven by regulations. Thus, in this case, legislation would probably be necessary, although it’s conceivable that the EPA could act (like it’s about to on CO2).
  • In the case of the large grids run by ISOs and RTOs, it’s possible that such a change in dispatch methodology could be made by the federal executive branch, if indeed the FERC has the power to mandate such a change
  • Effect on Nuclear With respect to the impacts of including environmental costs in plant dispatch order determination, I’ve mainly discussed the effects on gas vs. coal. Indeed, a switch from coal to gas would be the main impact of such a policy change. As for nuclear, as well as renewables, the direct/immediate impact would be minimal. That is because both nuclear and renewable sources have high capital costs but very low variable costs. They also have very low environmental impacts; much lower than those of coal or gas. Thus, they will remain at the front of the dispatch queue, ahead of both coal and gas.

U.S. Government Confirms Link Between Earthquakes and Hydraulic Fracturing at Oil Price - 0 views

  • On 5 November an earthquake measuring 5.6 rattled Oklahoma and was felt as far away as Illinois. Until two years ago Oklahoma typically had about 50 earthquakes a year, but in 2010, 1,047 quakes shook the state. Why? In Lincoln County, where most of this past weekend's seismic incidents were centered, there are 181 injection wells, according to Matt Skinner, an official from the Oklahoma Corporation Commission, the agency which oversees oil and gas production in the state. Cause and effect? The practice of injecting water into deep rock formations causes earthquakes, both the U.S. Army and the U.S. Geological Survey have concluded.
  • The U.S. natural gas industry pumps a mixture of water and assorted chemicals deep underground to shatter sediment layers containing natural gas, a process called hydraulic fracturing, known more informally as “fracking.” While environmental groups have primarily focused on fracking’s capacity to pollute underground water, a more ominous byproduct emerges from U.S. government studies – that forcing fluids under high pressure deep underground produces increased regional seismic activity. As the U.S. natural gas industry mounts an unprecedented and expensive advertising campaign to convince the public that such practices are environmentally benign, U.S. government agencies have determined otherwise. According to the U.S. Army’s Rocky Mountain Arsenal website, the RMA drilled a deep well for disposing of the site’s liquid waste after the U.S. Environmental Protection Agency “concluded that this procedure is effective and protective of the environment.”  According to the RMA, “The Rocky Mountain Arsenal deep injection well was constructed in 1961, and was drilled to a depth of 12,045 feet” and 165 million gallons of Basin F liquid waste, consisting of “very salty water that includes some metals, chlorides, wastewater and toxic organics” was injected into the well during 1962-1966.
  • Why was the process halted? “The Army discontinued use of the well in February 1966 because of the possibility that the fluid injection was “triggering earthquakes in the area,” according to the RMA. In 1990, the “Earthquake Hazard Associated with Deep Well Injection--A Report to the U.S. Environmental Protection Agency” study of RMA events by Craig Nicholson, and R.I. Wesson stated simply, “Injection had been discontinued at the site in the previous year once the link between the fluid injection and the earlier series of earthquakes was established.” Twenty-five years later, “possibility” and ‘established” changed in the Environmental Protection Agency’s July 2001 87 page study, “Technical Program Overview: Underground Injection Control Regulations EPA 816-r-02-025,” which reported, “In 1967, the U.S. Army Corps of Engineers and the U.S. Geological Survey (USGS) determined that a deep, hazardous waste disposal well at the Rocky Mountain Arsenal was causing significant seismic events in the vicinity of Denver, Colorado.” There is a significant divergence between “possibility,” “established” and “was causing,” and the most recent report was a decade ago. Much hydraulic fracturing to liberate shale oil gas in the Marcellus shale has occurred since.

  • According to the USGS website, under the undated heading, “Can we cause earthquakes? Is there any way to prevent earthquakes?” the agency notes, “Earthquakes induced by human activity have been documented in a few locations in the United States, Japan, and Canada. The cause was injection of fluids into deep wells for waste disposal and secondary recovery of oil, and the use of reservoirs for water supplies. Most of these earthquakes were minor. The largest and most widely known resulted from fluid injection at the Rocky Mountain Arsenal near Denver, Colorado. In 1967, an earthquake of magnitude 5.5 followed a series of smaller earthquakes. Injection had been discontinued at the site in the previous year once the link between the fluid injection and the earlier series of earthquakes was established.” Note the phrase, “Once the link between the fluid injection and the earlier series of earthquakes was established.” So both the U.S Army and the U.S. Geological Survey over fifty years of research confirm on a federal level that that “fluid injection” introduces subterranean instability and is a contributory factor in inducing increased seismic activity.” How about “causing significant seismic events?”
  • Fast forward to the present. Overseas, last month Britain’s Cuadrilla Resources announced that it has discovered huge underground deposits of natural gas in Lancashire, up to 200 trillion cubic feet of gas in all. On 2 November a report commissioned by Cuadrilla Resources acknowledged that hydraulic fracturing was responsible for two tremors which hit Lancashire and possibly as many as fifty separate earth tremors overall. The British Geological Survey also linked smaller quakes in the Blackpool area to fracking. BGS Dr. Brian Baptie said, “It seems quite likely that they are related,” noting, “We had a couple of instruments close to the site and they show that both events occurred near the site and at a shallow depth.” But, back to Oklahoma. Austin Holland’s August 2011 report, “Examination of Possibly Induced Seismicity from Hydraulic Fracturing in the Eola Field, Garvin County, Oklahoma” Oklahoma Geological Survey OF1-2011, studied 43 earthquakes that occurred on 18 January, ranging in intensity from 1.0 to 2.8 Md (milliDarcies.) While the report’s conclusions are understandably cautious, it does state, “Our analysis showed that shortly after hydraulic fracturing began small earthquakes started occurring, and more than 50 were identified, of which 43 were large enough to be located.”
  • Sensitized to the issue, the oil and natural gas industry has been quick to dismiss the charges and deluge the public with a plethora of televisions advertisements about how natural gas from shale deposits is not only America’s future, but provides jobs and energy companies are responsible custodians of the environment. It seems likely that Washington will eventually be forced to address the issue, as the U.S. Army and the USGS have noted a causal link between the forced injection of liquids underground and increased seismic activity. While the Oklahoma quake caused a deal of property damage, had lives been lost, the policy would most certainly have come under increased scrutiny from the legal community. While polluting a local community’s water supply is a local tragedy barely heard inside the Beltway, an earthquake ranging from Oklahoma to Illinois, Kansas, Arkansas, Tennessee and Texas is an issue that might yet shake voters out of their torpor, and national elections are slightly less than a year away.

EPA Finds Compound Used in Fracking in Wyoming Aquifer [10Nov11]f - 0 views

  • As the country awaits results from a nationwide safety study on the natural gas drilling process of fracking, a separate government investigation into contamination in a place where residents have long complained [1] that drilling fouled their water has turned up alarming levels of underground pollution. A pair of environmental monitoring wells drilled deep into an aquifer in Pavillion, Wyo., contain high levels of cancer-causing compounds and at least one chemical commonly used in hydraulic fracturing, according to new water test results [2] released yesterday by the Environmental Protection Agency.
  • The findings are consistent with water samples the EPA has collected from at least 42 homes in the area since 2008, when ProPublica began reporting [3] on foul water and health concerns in Pavillion and the agency started investigating reports of contamination there. Last year -- after warning residents not to drink [4] or cook with the water and to ventilate their homes when they showered -- the EPA drilled the monitoring wells to get a more precise picture of the extent of the contamination.
  • The Pavillion area has been drilled extensively for natural gas over the last two decades and is home to hundreds of gas wells. Residents have alleged for nearly a decade [1] that the drilling -- and hydraulic fracturing in particular -- has caused their water to turn black and smell like gasoline. Some residents say they suffer neurological impairment [5], loss of smell, and nerve pain they associate with exposure to pollutants. The gas industry -- led by the Canadian company EnCana, which owns the wells in Pavillion -- has denied that its activities are responsible for the contamination. EnCana has, however, supplied drinking water to residents.

  • The information released yesterday by the EPA was limited to raw sampling data: The agency did not interpret the findings or make any attempt to identify the source of the pollution. From the start of its investigation, the EPA has been careful to consider all possible causes of the contamination and to distance its inquiry from the controversy around hydraulic fracturing. Still, the chemical compounds the EPA detected are consistent with those produced from drilling processes, including one -- a solvent called 2-Butoxyethanol (2-BE) -- widely used in the process of hydraulic fracturing. The agency said it had not found contaminants such as nitrates and fertilizers that would have signaled that agricultural activities were to blame.

Mexico Scraps Plans to Build 10 Nuclear Power Plants in Favor of Using Gas [04Nov11] - 0 views

  • Mexico, one of three Latin American nations that uses nuclear power, is abandoning plans to build as many as 10 new reactors and will focus on natural gas-fired electricity plants after boosting discoveries of the fuel. The country, which found evidence of trillions of cubic feet of gas in the past year, is “changing all its decisions, amid the very abundant existence of natural-gas deposits,” Energy Minister Jordy Herrera said in a Nov. 1 interview. Mexico will seek private investment of about $10 billion during five years to expand its natural gas pipeline network, he said.
  • Mexico, Latin America’s second-largest economy, is boosting estimated gas reserves after Petroleos Mexicanos discovered new deposits in deep waters of the Gulf of Mexico and shale gas in the border state of Coahuila. The country was considering nuclear power as part of plans to boost capacity by almost three-quarters to 86 gigawatts within 15 years, from about 50 gigawatts, and now prefers gas for cost reasons, he said.
  • “This is a very good decision by the Mexican government,” said James Williams, an economist at WTRG Economics, an energy research firm in London, Arkansas. With a power generation project based on gas “you can build multiple plants at a much lower cost and much faster pace than a nuclear facility.”

Energy Forecast: Fracking in China, Nuclear Uncertain, CO2 Up [09Nov11] - 0 views

  • This year’s World Energy Outlook report has been published by the International Energy Agency, and says wealthy and industrializing countries are stuck on policies that threaten to lock in “an insecure, inefficient and high-carbon energy system.”You can read worldwide coverage of the report here. Fiona Harvey of the Guardian has a piece on the report that focuses on the inexorable trajectories for carbon dioxide, driven by soaring energy demand in Asia.A variety of graphs and slides can be reviewed here:
  • According to the report, Russia will long remain the world’s leading producer of natural gas, but exploitation of shale deposits in the United States, and increasingly in China, will greatly boost production in those countries (which will be in second and third place for gas production in 2035).Last month, in an interview with James Kanter of The Times and International Herald Tribune, the new head of the energy agency, Maria van der Hoeven, discussed one point made in the report today — that concerns raised by the damage to the Fukushima Daiichi power plant could continue to dampen expansion of nuclear power and add to the challenge of avoiding a big accumulation of carbon dioxide, saying: “Such a reduction would certainly make it more difficult for the world to meet the goal of stabilizing the rise in temperature to 2 degrees Centigrade.”
  • Here’s the summary of the main points, released today by the agency: “Growth, prosperity and rising population will inevitably push up energy needs over the coming decades. But we cannot continue to rely on insecure and environmentally unsustainable uses of energy,” said IEA Executive Director Maria van der Hoeven. “Governments need to introduce stronger measures to drive investment in efficient and low-carbon technologies. The Fukushima nuclear accident, the turmoil in parts of the Middle East and North Africa and a sharp rebound in energy demand in 2010 which pushed CO2 emissions to a record high, highlight the urgency and the scale of the challenge.”

  • In the WEO’s central New Policies Scenario, which assumes that recent government commitments are implemented in a cautious manner, primary energy demand increases by one-third between 2010 and 2035, with 90% of the growth in non-OECD economies. China consolidates its position as the world’s largest energy consumer: it consumes nearly 70% more energy than the United States by 2035, even though, by then, per capita demand in China is still less than half the level in the United States. The share of fossil fuels in global primary energy consumption falls from around 81% today to 75% in 2035. Renewables increase from 13% of the mix today to 18% in 2035; the growth in renewables is underpinned by subsidies that rise from $64 billion in 2010 to $250 billion in 2035, support that in some cases cannot be taken for granted in this age of fiscal austerity. By contrast, subsidies for fossil fuels amounted to $409 billion in 2010.
  • Short-term pressures on oil markets are easing with the economic slowdown and the expected return of Libyan supply. But the average oil price remains high, approaching $120/barrel (in year-2010 dollars) in 2035. Reliance grows on a small number of producers: the increase in output from Middle East and North Africa (MENA) is over 90% of the required growth in world oil output to 2035. If, between 2011 and 2015, investment in the MENA region runs one-third lower than the $100 billion per year required, consumers could face a near-term rise in the oil price to $150/barrel.Oil demand rises from 87 million barrels per day (mb/d) in 2010 to 99 mb/d in 2035, with all the net growth coming from the transport sector in emerging economies. The passenger vehicle fleet doubles to almost 1.7 billion in 2035. Alternative technologies, such as hybrid and electric vehicles that use oil more efficiently or not at all, continue to advance but they take time to penetrate markets.
  • The use of coal – which met almost half of the increase in global energy demand over the last decade – rises 65% by 2035. Prospects for coal are especially sensitive to energy policies – notably in China, which today accounts for almost half of global demand. More efficient power plants and carbon capture and storage (CCS) technology could boost prospects for coal, but the latter still faces significant regulatory, policy and technical barriers that make its deployment uncertain.Fukushima Daiichi has raised questions about the future role of nuclear power. In the New Policies Scenario, nuclear output rises by over 70% by 2035, only slightly less than projected last year, as most countries with nuclear programmes have reaffirmed their commitment to them. But given the increased uncertainty, that could change. A special Low Nuclear Case examines what would happen if the anticipated contribution of nuclear to future energy supply were to be halved. While providing a boost to renewables, such a slowdown would increase import bills, heighten energy security concerns and make it harder and more expensive to combat climate change.
  • The future for natural gas is more certain: its share in the energy mix rises and gas use almost catches up with coal consumption, underscoring key findings from a recent WEO Special Report which examined whether the world is entering a “Golden Age of Gas”. One country set to benefit from increased demand for gas is Russia, which is the subject of a special in-depth study in WEO-2011. Key challenges for Russia are to finance a new generation of higher-cost oil and gas fields and to improve its energy efficiency. While Russia remains an important supplier to its traditional markets in Europe, a shift in its fossil fuel exports towards China and the Asia-Pacific gathers momentum. If Russia improved its energy efficiency to the levels of comparable OECD countries, it could reduce its primary energy use by almost one-third, an amount similar to the consumption of the United Kingdom. Potential savings of natural gas alone, at 180 bcm, are close to Russia’s net exports in 2010.
  • In the New Policies Scenario, cumulative CO2 emissions over the next 25 years amount to three-quarters of the total from the past 110 years, leading to a long-term average temperature rise of 3.5°C. China’s per-capita emissions match the OECD average in 2035. Were the new policies not implemented, we are on an even more dangerous track, to an increase of 6°C.“As each year passes without clear signals to drive investment in clean energy, the “lock-in” of high-carbon infrastructure is making it harder and more expensive to meet our energy security and climate goals,” said Fatih Birol, IEA Chief Economist. The WEO presents a 450 Scenario, which traces an energy path consistent with meeting the globally agreed goal of limiting the temperature rise to 2°C. Four-fifths of the total energy-related CO2 emissions permitted to 2035 in the 450 Scenario are already locked-in by existing capital stock, including power stations, buildings and factories. Without further action by 2017, the energy-related infrastructure then in place would generate all the CO2 emissions allowed in the 450 Scenario up to 2035. Delaying action is a false economy: for every $1 of investment in cleaner technology that is avoided in the power sector before 2020, an additional $4.30 would need to be spent after 2020 to compensate for the increased emissions.

Smoking Gun - Jan Lundberg antinuclear activist & heir to petroleum wealth [18Jul11] - 0 views

  • A ‘smoking gun’ article is one that reveals a direct connection between a fossil fuel or alternative energy system promoter and a strongly antinuclear attitude. One of my guiding theories about energy is that a great deal of the discussion about safety, cost, and waste disposal is really a cover for a normal business activity of competing for market share.
  • This weekend, I came across a site called Culture Change that provides some strong support for my theory about the real source of strength for the antinuclear industry. According to the information at the bottom of the home page, Culture Change was founded by Sustainable Energy Institute (formerly Fossil Fuels Policy Action), a nonprofit organization.Jan Lundberg, who has led the organization and its predecessor organizations since 1988, grew up in a wealthy family with a father who was a popular and respected petroleum industry analyst.
  • Lundberg tells an interesting story about his initial fundraising activities for his new non-profit group.Setting out to become a clearinghouse for energy data and policy, we had a tendency to go along with the buzzword “natural gas as a bridge fuel” — especially when my previous clients serving the petroleum industry until 1988 included natural gas utilities. They were and are represented by the American Gas Association, where I knew a few friendly executives. Upon starting a nonprofit group for the environment with an energy focus, I met with the AGA right away. I was anticipating one of their generous grants they were giving large environmental groups who were trumpeting the “natural gas is a bridge fuel” mantra.
  • ...5 more annotations...
  • Before entering into the non-profit world, he entered into the family business of oil industry analysis and claims to have achieved a fair amount of financial success. As Lundberg tells the tale, he stopped “punching the corporate time clock” in 1988 to found Fossil Fuels Policy Action.I had just learned about peak oil. Upon my press conference announcing the formation of Fossil Fuels Policy Action, USA Today’s headline was “Lundberg Lines up with Nature.” My picture with the story looked like I was a corporate fascist, not an acid-tripping hippie. The USA Today story led to an invitation to review Beyond Oil: The Threat to Food and Fuel in the Coming Decades, for the quarterly Population and Environment journal. In learning for the first time about peak oil (although I had questioned long-term growth in petroleum supplies), I was awakened to the bigger picture as never before. Natural gas was no answer. And I already knew that the supply crisis to come — I had helped predict the 1970s oil shocks — was to be a liquid fuels crisis.
  • As Oil Guru, Dan [Lundberg, my father] earned a regular Nightly Business Report commentary spot on the Public Broadcasting System television network in the early and mid-1980s. I helped edit or proof-read just about every one of those commentaries, and we delighted in the occasional opportunity to attack gasohol and ethanol for causing “agricultural strip mining” (as we did in the Lundberg Letter).
  • I slept on it and decided that I would not participate in this corrupt conspiracy. Instead, I had fun writing one of Fossil Fuels Policy Action’s first newsletters about this “bridge” argument and the background story that the gas industry was really competing with fuel oil for heating. I brought up the AGA’s funding for enviros and said I was rejecting it. I was crazy, I admit, for I was starting a new career with almost no savings and no guarantees. So I was not surprised when my main contact at AGA called me up and snarled, “Jan, are you on acid?!
  • Here is a quote from his July 10, 2011 post titled Nuclear Roulette: new book puts a nail in coffin of nukesCulture Change went beyond studying the problem soon after its founding in 1988: action and advocacy must get to the root of the crises to assure a livable future. Also, information overload and a diet of bad news kills much activism. So it’s hard to find reading material to strongly recommend. But the new book Nuclear Roulette: The Case Against the “Nuclear Renaissance” is must-have if one is fighting nukes today.
  • He goes to say the following:The uneconomic nature of nuclear power, and the lack of energy gain compared to cheap oil, are two huge reasons for society to quit flirting with more nuclear power, never mind the catastrophic record and certainty of more to come. Somehow the evidence and true track record of dozens of accidents and perhaps 300,000 to nearly 1,000,000 deaths from just Chernobyl, are brushed aside by corporate media and most governments. So, imaginative means of helping to end nuclear proliferation are crucial, the most careful and reasonable-sounding ones being included in summary form in Nuclear Roulette.

The Intermittency of Fossil Fuels & Nuclear [19Aug11] - 0 views

  • You’ve likely heard this argument before: “The wind doesn’t always blow and the sun doesn’t always shine, so we can’t rely on renewable energy.” However, a series of recent events undermine the false dichotomy that renewable energies are unreliable and that coal, nuclear and natural gas are reliable.
  • There are too many reasons to list in a single blogpost why depending on fossil and nuclear energies is dangerous, but one emerging trend is that coal, natural gas and even nuclear energy are not as reliable as they are touted to be. Take for instance the nuclear disaster still unfolding in Japan. On March 11, that country experienced a massive earthquake and the resulting tsunami knocked out several nuclear reactors on the coast. Three days later, an operator of a nearby wind farm in Japan restarted its turbines - turbines that were intentionally turned off  immediately after the earthquake. Several countries, including France and Germany, are now considering complete phase-outs of nuclear energy in favor of offshore wind energy in the aftermath of the Japanese disaster. Even China has suspended its nuclear reactor plans while more offshore wind farms are being planned off that country’s coast.
  • In another example much closer to home, here in the Southeast, some of TVA’s nuclear fleet is operating at lower levels due to extreme temperatures. When the water temperatures in the Tennessee River reach more than 90 degrees, the TVA Browns Ferry nuclear reactors cannot discharge the already-heated power plant water into the river. If water temperatures become too high in a natural body of water, like a river, the ecosystem can be damaged and fish kills may occur. This problem isn’t limited to nuclear power plants either.
  • ...5 more annotations...
  • Texas has been experiencing a terrible heat wave this summer - along with much of the rest of the country. According to the Dallas Morning News, this heat wave has caused more than 20 power plants to shut down, including coal and natural gas plants. On the other hand, Texan wind farms have been providing a steady, significant supply of electricity during the heat wave, in part because wind farms require no water to generate electricity. The American Wind Energy Association (AWEA) noted on their blog: “Wind plants are keeping the lights on and the air conditioners running for hundreds of thousands of homes in Texas.”
  • This near-threat of a blackout is not a one-time or seasonal ordeal for Texans. Earlier this year, when winter storms were hammering the Lone Star State, rolling blackouts occurred due to faltering fossil fuel plants. In February, 50 power plants failed and wind energy helped pick up the slack.
  • Although far from the steady winds of the Great Plains, Cape Wind Associates noted that if their offshore wind farm was already operational, the turbines would have been able to harness the power of the heat wave oppressing the Northeast, mostly at full capacity. Cape Wind, vying to be the nation’s first offshore wind farm, has a meteorological tower stationed off Nantucket Sound in Massachusetts. If Cape Wind had been built, it could have been using these oppressive heat waves to operate New England’s cooling air conditioners. These three examples would suggest that the reliability of fossil fuels and nuclear reactors has been overstated, as has the variability of wind.
  • So just how much electricity can wind energy realistically supply as a portion of the nation’s energy? A very thorough report completed by the U.S. Department of Energy in 2008 (completed during President George W. Bush’s tenure) presents one scenario where wind energy could provide 20% of the U.S.’s electrical power by 2030. To achieve this level, the U.S. Department of Energy estimates energy costs would increase only 50 cents per month per household. A more recent study, the Eastern Wind Integration and Transmission Study (EWITS), shows that wind could supply 30% of the Eastern Interconnect’s service area (all of the Eastern U.S. from Nebraska eastward) with the proper transmission upgrades. As wind farms become more spread out across the country, and are better connected to each other via transmission lines, the variability of wind energy further decreases. If the wind isn’t blowing in Nebraska, it may be blowing in North Carolina, or off the coast of Georgia and the electricity generated in any state can then be transported across the continent. A plan has been hatched in the European Union to acquire 50% of those member states’ electricity from wind energy by 2050 - mostly from offshore wind farms, spread around the continent and heavily connected with transmission lines.
  • With a significant amount of wind energy providing electricity in the U.S., what would happen if the wind ever stops blowing? Nothing really - the lights will stay on, refrigerators will keep running and air conditions will keep working. As it so happens, wind energy has made the U.S. electrical supply more diversified and protects us against periodic shut downs from those pesky, sometimes-unreliable fossil fuel power plants and nuclear reactors.
  •  
    a series of recent events undermine the false dichotomy that renewable energies are unreliable and that coal, nuclear and natural gas are reliable.

Battling for nuclear energy by exposing opposition motives [19Jul11] - 0 views

  • In the money-driven battle over our future energy supply choices, the people who fight nuclear energy have imagination on their side. They can, and often do, invent numerous scary tales about what might happen without the need to actually prove anything.
  • One of the most powerful weapons in their arsenal is the embedded fantasy that a nuclear reactor accident can lead to catastrophic consequences that cannot be accepted. This myth is doubly hard to dislodge because a large fraction of the nuclear energy professionals have been trained to believe it. When you want to train large numbers of slightly above average people to do their job with great care and attention to detail, it can be useful to exaggerate the potential consequences of a failure to perform. It is also a difficult myth to dislodge because the explanation of why it is impossible requires careful and often lengthy explanations of occasionally complex concepts.
  • The bottom lines of both Chernobyl and Fukushima tell me that the very worst that can realistically happen to nuclear fission reactors results in acceptable physical consequences when compared to the risk of insufficient power or the risk of using any other reliable source of power. The most negative consequences of both accidents resulted from the way that government leaders responded, both during the crisis stage and during the subsequent recoveries.

  • Instead of trying to explain the basis for those statements more fully, I’ll try to encourage people to consider the motives of people on various sides of the discussion. I also want to encourage nuclear energy supporters to look beyond the financial implications to the broader implications of a less reliable and dirtier electrical power system. When the focus is just on the finances, the opposition has an advantage – the potential gains from opposing nuclear energy often are concentrated in the hands of extremely interested parties while the costs are distributed widely enough to be less visible. That imbalance often leads to great passion in the opposition and too much apathy among the supporters. Over at Idaho Samizdat, Dan Yurman has written about the epic battle of political titans who are on opposing sides of the controversy regarding the relicensing and continued operation of the Indian Point Nuclear Power Station. Dan pointed out that there is a large sum of money at stake, but he put it in a way that does not sound too terrible to many people because it spreads out the pain.
  • In round numbers, if Indian Point is closed, wholesale electricity prices could rise by 12%.
  • A recent study quoted in a New York Times article put the initial additional cost of electricity without Indian Point at about $1.5 billion per year, which is a substantial sum of money if concentrated into the hands of a few thousand victors who tap the monthly bills of a few million people. Here is a comment that I added to Dan’s post:Dan – thank you for pointing out that the battle is not really a partisan one determined by political party affiliation. By my analysis, the real issue is the desire of natural gas suppliers to sell more gas at ever higher prices driven by a shift in the balance between supply and demand.
  • They never quite explain what is going to happen as we get closer and closer to the day when even fracking will not squeeze any more hydrocarbons out of the drying sponge that is the readily accessible part of the earth’s crust.The often touted “100 – year” supply of natural gas in the US has a lot of optimistic assumptions built in. First of all, it is only rounded up to 100 years – 2170 trillion cubic feet at the end of 2010 divided by 23 trillion cubic feet per year leaves just 94 years.
  • Secondly, the 2170 number provided by the Potential Gas Committee report includes all proven, probable, possible and speculative resources, without any analysis of the cost of extraction or moving them to a market. Many of the basins counted have no current pipelines and many of the basins are not large enough for economic recovery of the investment to build the infrastructure without far higher prices.Finally, all bets are off with regard to longevity if we increase the rate of burning up the precious raw materia
  • BTW – In case your readers are interested in the motives of a group like Riverkeepers, founded and led by Robert F. Kennedy, Jr., here is a link to a video clip of him explaining his support for natural gas.http://atomicinsights.com/2010/11/power-politics-rfk-jr-explains-how-pressure-from-activists-to-enforce-restrictions-on-coal-benefits-natural-gas.html
  • The organized opposition to the intelligent use of nuclear energy has often painted support for the technology as coming from faceless, money-hungry corporations. That caricature of the support purposely ignores the fact that there are large numbers of intelligent, well educated, responsible, and caring people who know a great deal about the technology and believe that it is the best available solution for many intransigent problems. There are efforts underway today, like the Nuclear Literacy Project and Go Nuclear, that are focused on showcasing the admirable people who like nuclear energy and want it to grow rapidly to serve society’s never ended thirst for reliable power at an affordable price with acceptable environmental impact.
  • The exaggerated, fanciful accident scenarios painted by the opposition are challenging to disprove.
  • I just read an excellent post on Yes Vermont Yankee about a coming decision that might help to illuminate the risk to society of continuing to let greedy antinuclear activists and their political friends dominate the discussion. According to Meredith’s post, Entergy must make a decision within just a week or so about whether or not to refuel Vermont Yankee in October. Since the sitting governor is dead set against the plant operating past its current license expiration in the summer of 2012, the $100 million dollar expense of refueling would only result in about 6 months of operation instead of the usual 18 months.Meredith has a novel solution to the dilemma – conserve the fuel currently in the plant by immediately cutting the power output to 25%.

The Death of Nuclear Power: The Five Global Energy Moves to Make Now [07Jun11] - 0 views

  • out
  • Nuclear power was gaining a lot of momentum prior to the terrible disaster at Japan's Fukushima powerplant in March.
  • But since then, atomic energy has come under increased scrutiny and once again drawn the ire of environmentalists who were just warming up to its carbon-free emissions.
  • ...16 more annotations...
  • The German government's decision to close all of its existing nuclear reactors by 2022 shows that this shift in sentiment is gaining traction. And it increases the likelihood that the nuclear-powerplant building boom that had seemed at hand will be set back. Without a doubt, this new reality will lead to global energy shortages and much-higher energy costs.But for us as investors, the real issue is this: Which sectors will step up to alleviate the shortfall resulting from the inevitable disappearance of nuclear power?
  • As the recent development in Germany so clearly illustrates, one key difficulty about major energy decisions is that far too many are political in nature.
  • Too often, rational scientific analysis and cost-benefit analyses are ignored as hard-line environmentalists push their own agendas. Many of the environmentalists' objections are valid - at least as far as they go. But more and more, those objections seem to include every source of energy that actually works.
  • Windmills are objectionable because they look ugly and kill birds. Geothermal energy is objectionable because it causes earthquakes. Even solar energy is objectionable because of the vast acreages of land required to house the solar panels
  • Replacing Nuclear Power Figuring out which energy sources will offset the decline in nuclear power output requires three calculations:
  • First, a calculation of the cost of an energy source - as it now exists - in its economically most practicable uses. However, much as we may like solar power, we are not about to get solar-powered automobiles; likewise, oil-fueled power stations are inefficient on many grounds.
  • Second, a calculation that demonstrates whether the cost of that energy source is likely to increase or decline. With oil and hydro-electric power, for instance, the cost is likely to increase: The richest oil wells have been tapped and the best rivers have been dammed. With solar, on the other hand, the cost could decline, given how quickly the technology is advancing.
  • And third, an estimate that includes our best guess as to whether hard-line environmentalists will win or lose in their attempt to prevent its use.
  • On nuclear energy, the environmentalists appear to have won - at least for the time being. Their victory probably extends to fusion power, if that ever becomes economical. Conversely, their battles against wind and solar power are futile, as there are no scary disaster scenarios involved.
  • I regard the German decision to abandon nuclear power as foolish, and it should make us very cautious when investing in large-scale German manufacturers, which may be made uncompetitive by excessive power costs. But as an investor, I think it opens up a number of profit opportunities.
  • Actions To Take: Environmental concerns have chased investment away from nuclear energy - at least for the time being. For that reason the nuclear build-out that was just starting to gain momentum now is likely to stumble. As investors, we must look for energy sources that will most likely replace lost nuclear power output. They include:
  • Shale Gas: Potential damage to the environment caused by "fracking," which is the process by which shale gas is extracted, has not impeded this industry's growth. Natural gas has grown increasingly popular, as it is relatively cheap and clean, and readily abundant in the United States. A recent study by the Massachusetts Institute of Technology (MIT) suggests that natural gas will provide 40% of U.S. energy needs in the future, up from 20% today. You might look at Chesapeake Energy Corp. (NYSE:CHK), the largest leaseholder in Pennsylvania's Marcellus Shale, which is trading at a reasonable 9.5 times projected 2012 earnings.
  • Shale gas. Tar sands. And solar energy. Let's look at each of the three - and identify the best ways to play them
  • Tar Sands: The Athabasca tar sands in Canada contain more oil than the Middle East. And at an oil price of $100 per barrel, it is highly profitable to extract. Of course, extraction makes a huge mess of the local environment, but environmentalists seem to have lost that battle - reasonably enough, in view of the "energy security" implications of dependence on the Middle East. A play I like here is Cenovus Energy Inc. (NYSE: CVE). It's a purer Athabasca play than Suncor Energy Inc. (NYSE: SU), but it's currently pricey at 16.5 times projected 2012 earnings. Suncor's cheaper at only 11 times projected 2012 earnings - so take your pick
  • Solar Energy: Of the many new energy sources that have received so much taxpayer money in the last five years, solar is the one with real potential. Unlike with wind farms, where there is almost no opportunity for massive technological improvement or cost reduction, there is great potential upside with solar power: The technology and economics of solar panels and their manufacture is improving steadily. Indeed, solar power seems likely to be competitive as a source of electricity without subsidy sometime around 2016-2020, if energy prices stay high.
  • There are a number of ways to play this. You can select a solar-panel manufacturer like the Chinese JA Solar Holdings Co. Ltd. (Nasdaq ADR: JASO), or a rectifier producer like Power-One Inc. (Nasdaq: PWER). JA Solar is trading at a startling forward Price/Earnings (P/E) ratio of less than 5.0, mostly likely because of the Chinese accounting scandals, whereas Power-One is also cheap at less than seven times forward earnings and is U.S.-domiciled. Again, take your pick, depending on which risks you are comfortable with.

Mexico Scrapping Plans to Build as Many as 10 Nuclear Plants [04Nov11] - 0 views

  • Nov. 3 (Bloomberg) -- Mexico, one of three Latin American nations that uses nuclear power, is abandoning plans to build as many as 10 new reactors and will focus on natural gas-fired electricity plants after boosting discoveries of the fuel.
  • The country, which found evidence of trillions of cubic feet of gas in the past year, is “changing all its decisions, amid the very abundant existence of natural-gas deposits,” Energy Minister Jordy Herrera said in a Nov. 1 interview. Mexico will seek private investment of about $10 billion during five years to expand its natural gas pipeline network, he said.
  • “This is a very good decision by the Mexican government,” said James Williams, an economist at WTRG Economics, an energy research firm in London, Arkansas. With a power generation project based on gas “you can build multiple plants at a much lower cost and much faster pace than a nuclear facility.”

If Indian Point Nuclear Closes, Plenty of Profits (for natural gas suppliers) [13Jul11] - 0 views

  •  
    (Diigo won't highlight this correctly, putting it in description!) "Matt Wald of the New York Times has finally figured out why there is such a strong push from well connected political types to close the Indian Point Nuclear Power Station. Unfortunately, he and his editor have chosen to put that answer at the very bottom of his recent article titled If Indian Point Closes, Plenty of Challenges . When the demand for natural gas increases, the balance between supply and demand shifts in favor of the sellers, so price inexorably increases. Here is the closing paragraph of that article. It should raise alarm bells for anyone who is a power purchaser instead of a power seller. That description applies to the vast majority of us; part of the challenge is that it only costs each of us a little while concentrating the spoils in the hands of a few victors. Closing the Indian Point reactors would, however, hardly be gloom and doom for everyone. Any company that runs a generator in downstate New York ends up selling its output at a higher price, and would share in the $1.4 billion a year that Con Edison says its customers will pay if the nuclear plant closes."

Fracking Radiation Targeted By DOE, GE [03Aug11] - 0 views

  • The Department of Energy and General Electric will spend $2 million over the next two years to remove naturally occurring radioactive materials from the fracking fluids produced by America’s booming shale-gas industry. The New York State Department of Health has identified Radium-226 as a radionuclide of particular concern in the Marcellus Shale formation deep beneath the Appalachian Mountains. In hydraulic fracturing operations, drillers force water and a mixture of chemicals into wells to shatter the shale and free natural gas. The brine that returns to the surface has been found to contain up to 16,000 picoCuries per liter of radium-226 (pdf). The discharge limit in effluent for Radium 226 is 60 pCi/L, and the EPA’s drinking water standard is 5 pCi/L.
  • Uranium and Radon-222 have also been found in water returning to the surface from deep shale wells. In Pennsylvania, produced water has been discharged into streams and rivers from the state’s 71,000 wells after conventional wastewater treatment but without radiation testing, according to the Pittsburgh Post-Gazette and The New York Times, which drew attention to the radioactive contamination earlier this year after studying internal EPA documents: The documents reveal that the wastewater, which is sometimes hauled to sewage plants not designed to treat it and then discharged into rivers that supply drinking water, contains radioactivity at levels higher than previously known, and far higher than the level that federal regulators say is safe for these treatment plants to handle. via The New York Times
  • GE’s Global Research lab in Niskayuna, NY has proposed removing radioactive elements from produced waters and brine using a membrane distillation system similar to conventional reverse osmosis, but designed specifically to capture these radioactive materials. GE will spend $400,000 on the project and DOE will supply $1.6 million. The Energy Department announced the project Monday. The process will produce concentrated radioactive waste, which will be disposed of through conventional means, which usually means storage in sealed containers for deep geological disposal. The government is seeking to address environmental concerns without stemming a boom in cheap gas unleashed by hydraulic fracturing, or fracking, in shale formations.

The Thorium Reactor, A Nuclear Energy Alternative [19Sep11] - 0 views

  • After Fukushima a great deal of awareness on the dangers of nuclear energy has ignited a series of reactions in society, mainly a generalized rejection to nuclear energy and a call to develop cleaner and safer sources of energy. When thinking about nuclear energy mainly 2 sources come to peoples minds, solar and wind power condemning any sort of nuclear power.  Nuclear power has been associated with Weapons of Mass Destruction, radiation sickness and disease.  However, this is not due to the nuclear power itself but due to the nuclear fuel used to generate this nuclear power.
  • In today’s world the main fuel for nuclear power is a naturally occurring radioactive mineral, Uranium.  This mineral is one of the most dense metals in the periodic table which allows it to reach a chain reaction that can yield huge amounts of energy that can be exploited for an extended period of time.  Unfortunately the nuclear fuel cycle of Uranium produced extremely dangerous byproducts, commonly known as nuclear waste.  These are produced in liquid, solid and gaseous form in a wide variety of deadly substances, such as: Iodine 131 Strontium 90 Cesium 137 Euricium 155 Krypton 85 Cadmium 113 Tin 121 Samarium 151 Technetium-99
  • The above are just some of the most common byproducts, (better known as nuclear waste) of a nuclear fuel cycle, all of these substances are extremely poisonous, causing a variety of diseases, cancers and genetic mutations to the victim.  The worst part is that most of them remain in the environment of decades or even thousands of years, so if accidentally released to the environment they become a problem that future generations have to deal with.  Therefore, in nuclear energy the problem is in the fuel not in the engine. Lets start with the Thorium Reactors.  Thorium is a naturally occurring radioactive chemical element, found in abundance throughout the world.  It is estimated that every cubic meter of earth’s crust contains about 12 grams of this mineral, enough quantity to power 1 person’s electricity consumption for 12-25 years.  Energy is produced from thorium in a process known as the Thorium Fuel Cycle, were a nuclear fuel cycle is derived from the natural abundant isotope of thorium.
  • ...2 more annotations...
  • Thorium can be used as fuel in a nuclear reactor, and it is a fertile material, which allows it to be used to produce nuclear fuel in a breeder reactor.  These are some of the benefits of Thorium reactors compared to Uranium. Weapons-grade fissionable material is harder to retrieve safely and clandestinely from a thorium reactor; Thorium produces 10 to 10,000 times less long-lived radioactive waste; Thorium comes out of the ground as a 100% pure, usable isotope, which does not require enrichment, whereas natural uranium contains only 0.7% fissionable U-235; Thorium cannot sustain a nuclear chain reaction without priming,[22] so fission stops by default. The following conference by Kirk Sorensen explains a Liquid-Fuoride Thorium Reactor a next generation nuclear reactor.

The Environmental Case for Nuclear Energy - Korea [26Sep11] - 0 views

  • Six months after the Fukushima disaster, the repercussions of history’s second-largest nuclear meltdown are still being felt, not only in Japan but around the world. Predictably, people are rethinking the wisdom of relying on nuclear power. The German and Swiss governments have pledged to phase out the use of nuclear power, and Italy has shelved plans to build new reactors. Public debate on future nuclear energy use continues in the United Kingdom, Japan, Finland, and other countries.So far, it is unclear what the reaction of the Korean government will be. Certainly, the public backlash to nuclear energy that has occurred elsewhere in the world is also evident in Korea; according to one study, opposition to nuclear energy in Korea has tripled since the Fukushima disaster. However, there are countervailing considerations here as well, which have caused policy-makers to move cautiously. Korea’s economy is often seen as particularly reliant on the use of nuclear power due to its lack of fossil fuel resources, while Korean companies are some of the world’s most important builders (and exporters) of nuclear power stations.
  • There are three primary reasons why nuclear power is safer and greener than power generated using conventional fossil fuels. First ― and most importantly ― nuclear power does not directly result in the emission of greenhouse gases. Even when you take a life-cycle approach and factor in the greenhouse gas emissions from the construction of the plant, there is no contest. Fossil fuels ― whether coal, oil, or natural gas ― create far more global warming.
  • The negative effects of climate change will vastly outweigh the human and environmental consequences of even a thousand Fukushimas. This is not the place to survey all the dire warnings that have been coming out of the scientific community; suffice it to quote U.N. Secretary General Ban Ki-moon’s concise statement that climate change is the world’s “only one truly existential threat … the great moral imperative of our era.” A warming earth will not only lead to death and displacement in far-off locales, either. Typhoons are already hitting the peninsula with greater intensity due to the warming air, and a recent study warns that global warming will cause Korea to see greatly increased rates of contagious diseases such as cholera and bacillary dysentery.

  • As the world’s ninth largest emitter of greenhouse gases, it should be (and is) a major priority for Korea to reduce emissions, and realistically that can only be accomplished by increasing the use of nuclear power. As Barack Obama noted with regard to the United States’ energy consumption, “Nuclear energy remains our largest source of fuel that produces no carbon emissions. It’s that simple. (One plant) will cut carbon pollution by 16 million tons each year when compared to a similar coal plant. That’s like taking 3.5 million cars off the road.” Environmentalists have traditionally disdained nuclear power, but even green activists cannot argue with that logic, and increasing numbers of them ― Patrick Moore, James Lovelock, Stewart Brand and the late Bishop Hugh Montefiore being prominent examples ― have become supporters of the smart use of nuclear power.
  • Second, the immediate dangers to human health of conventional air pollution outweigh the dangers of nuclear radiation. In 2009, the Seoul Metropolitan Government measured an average PM10 (particulate) concentration in the city of 53.8 g/m3, a figure that is roughly twice the level in other developed nations. According to the Gyeonggi Research Institute, PM10 pollution leads to 10,000 premature deaths per year in and around Seoul, while the Korea Economic Institute has estimated its social cost at 10 trillion won. While sulfur dioxide levels in the region have decreased significantly since the 1980s, the concentration of nitrogen dioxide in the air has not decreased, and ground-level ozone levels remain high. Unlike fossil fuels, nuclear power does not result in the release of any of these dangerous pollutants that fill the skies around Seoul, creating health hazards that are no less serious for often going unnoticed.
  • And third, the environmental and safety consequences of extracting and transporting fossil fuels are far greater than those involved with the production of nuclear power. Korea is one of the largest importers of Indonesian coal for use in power plants, for example. This coal is not always mined with a high level of environmental and safety protections, with a predictable result of air, water, and land pollution in one of Asia’s most biologically sensitive ecosystems. Coal mining is also one of the world’s more dangerous occupations, as evidenced by the many tragic disasters involving poorly managed Chinese mines. While natural gas is certainly a better option than coal, its distribution too can be problematic, whether by ship or through the recently proposed pipeline that would slice down through Siberia and North Korea to provide direct access to Russian gas.
  • What about truly green renewable energy, some might ask ― solar, wind, geothermal, hydroelectric, and tidal energy? Of course, Korea would be a safer and more sustainable place if these clean renewable resources were able to cover the country’s energy needs. However, the country is not particularly well suited for hydroelectric projects, while the other forms of renewable energy production are expensive, and are unfortunately likely to remain so for the foreseeable future. The fact is that most Koreans will not want to pay the significantly higher energy prices that would result from the widespread use of clean renewables, and in a democratic society, the government is unlikely to force them to do so. Thus, we are left with two realistic options: fossil fuels or nuclear. From an environmental perspective, it would truly be a disaster to abandon the latter.

The nuclear power plans that have survived Fukushima [28Sep11] - 0 views

  • SciDev.Net reporters from around the world tell us which countries are set on developing nuclear energy despite the Fukushima accident. The quest for energy independence, rising power needs and a desire for political weight all mean that few developing countries with nuclear ambitions have abandoned them in the light of the Fukushima accident. Jordan's planned nuclear plant is part of a strategy to deal with acute water and energy shortages.
  • The Jordan Atomic Energy Commission (JAEC) wants Jordan to get 60 per cent of its energy from nuclear by 2035. Currently, obtaining energy from neighbouring Arab countries costs Jordan about a fifth of its gross domestic product. The country is also one of the world's most water-poor nations. Jordan plans to desalinate sea water from the Gulf of Aqaba to the south, then pump it to population centres in Amman, Irbid, and Zarqa, using its nuclear-derived energy. After the Fukushima disaster, Jordan started re-evaluating safety procedures for its nuclear reactor, scheduled to begin construction in 2013. The country also considered more safety procedures for construction and in ongoing geological and environmental investigations.
  • The government would not reverse its decision to build nuclear reactors in Jordan because of the Fukushima disaster," says Abdel-Halim Wreikat, vice Chairman of the JAEC. "Our plant type is a third-generation pressurised water reactor, and it is safer than the Fukushima boiling water reactor." Wreikat argues that "the nuclear option for Jordan at the moment is better than renewable energy options such as solar and wind, as they are still of high cost." But some Jordanian researchers disagree. "The cost of electricity generated from solar plants comes down each year by about five per cent, while the cost of producing electricity from nuclear power is rising year after year," says Ahmed Al-Salaymeh, director of the Energy Centre at the University of Jordan. He called for more economic feasibility studies of the nuclear option.
  • ...20 more annotations...
  • And Ahmad Al-Malabeh, a professor in the Earth and Environmental Sciences department of Hashemite University, adds: "Jordan is rich not only in solar and wind resources, but also in oil shale rock, from which we can extract oil that can cover Jordan's energy needs in the coming years, starting between 2016 and 2017 ... this could give us more time to have more economically feasible renewable energy."
  • Finance, rather than Fukushima, may delay South Africa's nuclear plans, which were approved just five days after the Japanese disaster. South Africa remains resolute in its plans to build six new nuclear reactors by 2030. Katse Maphoto, the director of Nuclear Safety, Liabilities and Emergency Management at the Department of Energy, says that the government conducted a safety review of its two nuclear reactors in Cape Town, following the Fukushima event.
  • Vietnam's nuclear energy targets remain ambitious despite scientists' warning of a tsunami risk. Vietnam's plan to power 10 per cent of its electricity grid with nuclear energy within 20 years is the most ambitious nuclear energy plan in South-East Asia. The country's first nuclear plant, Ninh Thuan, is to be built with support from a state-owned Russian energy company and completed by 2020. Le Huy Minh, director of the Earthquake and Tsunami Warning Centre at Vietnam's Institute of Geophysics, has warned that Vietnam's coast would be affected by tsunamis in the adjacent South China Sea.
  • Larkin says nuclear energy is the only alternative to coal for generating adequate electricity. "What other alternative do we have? Renewables are barely going to do anything," he said. He argues that nuclear is capable of supplying 85 per cent of the base load, or constantly needed, power supply, while solar energy can only produce between 17 and 25 per cent. But, despite government confidence, Larkin says that a shortage of money may delay the country's nuclear plans.
  • The government has said yes but hasn't said how it will pay for it. This is going to end up delaying by 15 years any plans to build a nuclear station."
  • The Ninh Thuan nuclear plant would sit 80 to 100 kilometres from a fault line on the Vietnamese coast, potentially exposing it to tsunamis, according to state media. But Vuong Huu Tan, president of the state-owned Vietnam Atomic Energy Commission, told state media in March, however, that lessons from the Fukushima accident will help Vietnam develop safe technologies. And John Morris, an Australia-based energy consultant who has worked as a geologist in Vietnam, says the seismic risk for nuclear power plants in the country would not be "a major issue" as long as the plants were built properly. Japan's nuclear plants are "a lot more earthquake prone" than Vietnam's would be, he adds.
  • Undeterred by Fukushima, Nigeria is forging ahead with nuclear collaborations. There is no need to panic because of the Fukushima accident, says Shamsideen Elegba, chair of the Forum of Nuclear Regulatory Bodies in Africa. Nigeria has the necessary regulatory system to keep nuclear activities safe. "The Nigerian Nuclear Regulatory Authority [NNRA] has established itself as a credible organisation for regulatory oversight on all uses of ionising radiation, nuclear materials and radioactive sources," says Elegba who was, until recently, the NNRA's director general.
  • Vietnam is unlikely to experience much in the way of anti-nuclear protests, unlike neighbouring Indonesia and the Philippines, where civil society groups have had more influence, says Kevin Punzalan, an energy expert at De La Salle University in the Philippines. Warnings from the Vietnamese scientific community may force the country's ruling communist party to choose alternative locations for nuclear reactors, or to modify reactor designs, but probably will not cause extreme shifts in the one-party state's nuclear energy strategy, Punzalan tells SciDev.Net.
  • Will the Philippines' plans to rehabilitate a never-used nuclear power plant survive the Fukushima accident? The Philippines is under a 25-year moratorium on the use of nuclear energy which expires in 2022. The government says it remains open to harnessing nuclear energy as a long-term solution to growing electricity demand, and its Department of Science and Technology has been making public pronouncements in favour of pursuing nuclear energy since the Fukushima accident. Privately, however, DOST officials acknowledge that the accident has put back their job of winning the public over to nuclear by four or five years.
  • In the meantime, the government is trying to build capacity. The country lacks, for example, the technical expertise. Carmencita Bariso, assistant director of the Department of Energy's planning bureau, says that, despite the Fukushima accident, her organisation has continued with a study on the viability, safety and social acceptability of nuclear energy. Bariso says the study would include a proposal for "a way forward" for the Bataan Nuclear Power Plant, the first nuclear reactor in South East Asia at the time of its completion in 1985. The $2.3-billion Westinghouse light water reactor, about 60 miles north of the capital, Manila, was never used, though it has the potential to generate 621 megawatts of power. President Benigno Aquino III, whose mother, President Corazon Aquino, halted work on the facility in 1986 because of corruption and safety issues, has said it will never be used as a nuclear reactor but could be privatised and redeveloped as a conventional power plant.
  • But Mark Cojuangco, former lawmaker, authored a bill in 2008 seeking to start commercial nuclear operations at the Bataan reactor. His bill was not passed before Congress adjourned last year and he acknowledges that the Fukushima accident has made his struggle more difficult. "To go nuclear is still the right thing to do," he says. "But this requires a societal decision. We are going to spark public debates with a vengeance as soon as the reports from Fukushima are out." Amended bills seeking both to restart the reactor, and to close the issue by allowing either conversion or permanent closure, are pending in both the House and the Senate. Greenpeace, which campaigns against nuclear power, believes the Fukushima accident has dimmed the chances of commissioning the Bataan plant because of "increased awareness of what radioactivity can do to a place". Many parts of the country are prone to earthquakes and other natural disasters, which critics say makes it unsuitable both for the siting of nuclear power stations and the disposal of radioactive waste.
  • In Kenya, nuclear proponents argue for a geothermal – nuclear mix In the same month as the Fukushima accident, inspectors from the International Atomic Energy Agency approved Kenya's application for its first nuclear power station (31 March), a 35,000 megawatt facility to be built at a cost of Sh950 billion (US$9.8 billion) on a 200-acre plot on the Athi Plains, about 50km from Nairobi
  • The plant, with construction driven by Kenya's Nuclear Electricity Project Committee, should be commissioned in 2022. The government claims it could satisfy all of Kenya's energy needs until 2040. The demand for electricity is overwhelming in Kenya. Less than half of residents in the capital, Nairobi, have grid electricity, while the rural rate is two per cent. James Rege, Chairman of the Parliamentary Committee on Energy, Communication and Information, takes a broader view than the official government line, saying that geothermal energy, from the Rift Valley project is the most promising option. It has a high production cost but remains the country's "best hope". Nuclear should be included as "backup". "We are viewing nuclear energy as an alternative source of power. The cost of fossil fuel keeps escalating and ordinary Kenyans can't afford it," Rege tells SciDev.Net.
  • Hydropower is limited by rivers running dry, he says. And switching the country's arable land to biofuel production would threaten food supplies. David Otwoma, secretary to the Energy Ministry's Nuclear Electricity Development Project, agrees that Kenya will not be able to industrialise without diversifying its energy mix to include more geothermal, nuclear and coal. Otwoma believes the expense of generating nuclear energy could one day be met through shared regional projects but, until then, Kenya has to move forward on its own. According to Rege, much as the nuclear energy alternative is promising, it is extremely important to take into consideration the Fukushima accident. "Data is available and it must be one step at a time without rushing things," he says. Otwoma says the new nuclear Kenya can develop a good nuclear safety culture from the outset, "but to do this we need to be willing to learn all the lessons and embrace them, not forget them and assume that won't happen to us".
  • But the government adopted its Integrated Resource Plan (IRP) for 2010-2030 five days after the Fukushima accident. Elliot Mulane, communications manager for the South African Nuclear Energy Corporation, (NECSA) a public company established under the 1999 Nuclear Energy Act that promotes nuclear research, said the timing of the decision indicated "the confidence that the government has in nuclear technologies". And Dipuo Peters, energy minister, reiterated the commitment in her budget announcement earlier this year (26 May), saying: "We are still convinced that nuclear power is a necessary part of our strategy that seeks to reduce our greenhouse gas emissions through a diversified portfolio, comprising some fossil-based, renewable and energy efficiency technologies". James Larkin, director of the Radiation and Health Physics Unit at the University of the Witwatersrand, believes South Africa is likely to go for the relatively cheap, South Korean generation three reactor.
  • It is not only that we say so: an international audit came here in 2006 to assess our procedure and processes and confirmed the same. Elegba is firmly of the view that blame for the Fukushima accident should be allocated to nature rather than human error. "Japan is one of the leaders not only in that industry, but in terms of regulatory oversight. They have a very rigorous system of licensing. We have to make a distinction between a natural event, or series of natural events and engineering infrastructure, regulatory infrastructure, and safety oversight." Erepamo Osaisai, Director General of the Nigeria Atomic Energy Commission (NAEC), has said there is "no going back" on Nigeria's nuclear energy project after Fukushima.
  • Nigeria is likely to recruit the Russian State Corporation for Atomic Energy, ROSATOM, to build its first proposed nuclear plant. A delegation visited Nigeria (26- 28 July) and a bilateral document is to be finalised before December. Nikolay Spassy, director general of the corporation, said during the visit: "The peaceful use of nuclear power is the bedrock of development, and achieving [Nigeria's] goal of being one of the twenty most developed countries by the year 2020 would depend heavily on developing nuclear power plants." ROSATOM points out that the International Atomic Energy Agency monitors and regulates power plant construction in previously non-nuclear countries. But Nnimmo Bassey, executive director of the Environmental Rights Action/Friends of the Earth Nigeria (ERA/FoEN), said "We cannot see the logic behind the government's support for a technology that former promoters in Europe, and other technologically advanced nations, are now applying brakes to. "What Nigeria needs now is investment in safe alternatives that will not harm the environment and the people. We cannot accept the nuclear option."
  • Thirsty for electricity, and desirous of political clout, Egypt is determined that neither Fukushima ― nor revolution ― will derail its nuclear plans. Egypt was the first country in the Middle East and North Africa to own a nuclear programme, launching a research reactor in 1961. In 2007 Egypt 'unfroze' a nuclear programme that had stalled in the aftermath of the Chernobyl disaster. After the Egyptian uprising in early 2011, and the Fukushima accident, the government postponed an international tender for the construction of its first plant.
  • Yassin Ibrahim, chairman of the Nuclear Power Plants Authority, told SciDev.Net: "We put additional procedures in place to avoid any states of emergency but, because of the uprising, the tender will be postponed until we have political stability after the presidential and parliamentary election at the end of 2011". Ibrahim denies the nuclear programme could be cancelled, saying: "The design specifications for the Egyptian nuclear plant take into account resistance to earthquakes and tsunamis, including those greater in magnitude than any that have happened in the region for the last four thousand years. "The reactor type is of the third generation of pressurised water reactors, which have not resulted in any adverse effects to the environment since they began operation in the early sixties."
  • Ibrahim El-Osery, a consultant in nuclear affairs and energy at the country's Nuclear Power Plants Authority, points out that Egypt's limited resources of oil and natural gas will run out in 20 years. "Then we will have to import electricity, and we can't rely on renewable energy as it is still not economic yet — Egypt in 2010 produced only two per cent of its needs through it." But there are other motives for going nuclear, says Nadia Sharara, professor of mineralogy at Assiut University. "Owning nuclear plants is a political decision in the first place, especially in our region. And any state that has acquired nuclear technology has political weight in the international community," she says. "Egypt has the potential to own this power as Egypt's Nuclear Materials Authority estimates there are 15,000 tons of untapped uranium in Egypt." And she points out it is about staying ahead with technology too. "If Egypt freezes its programme now because of the Fukushima nuclear disaster it will fall behind in many science research fields for at least the next 50 years," she warned.

How To Remove Radioactive Iodine-131 From Drinking Water [07Apr11] - 0 views

  • The Environmental Protection Agency recommends reverse osmosis water treatment to remove radioactive isotopes that emit beta-particle radiation. But iodine-131, a beta emitter, is typically present in water as a dissolved gas, and reverse osmosis is known to be ineffective at capturing gases. A combination of technologies, however, may remove most or all of the iodine-131 that finds its way into tap water, all available in consumer products for home water treatment.
  • When it found iodine-131 in drinking water samples from Boise, Idaho and Richland, Washington this weekend, the EPA declared: An infant would have to drink almost 7,000 liters of this water to receive a radiation dose equivalent to a day’s worth of the natural background radiation exposure we experience continuously from natural sources of radioactivity in our environment.” But not everyone accepts the government’s reassurances. Notably, Physicians for Social Responsibility has insisted there is no safe level of exposure to radionuclides, regardless of the fact that we encounter them naturally:
  • There is no safe level of radionuclide exposure, whether from food, water or other sources. Period,” said Jeff Patterson, DO, immediate past president of Physicians for Social Responsibility. “Exposure to radionuclides, such as iodine-131 and cesium-137, increases the incidence of cancer. For this reason, every effort must be taken to minimize the radionuclide content in food and water.” via Physicians for Social Responsibility, psr.org No matter where you stand on that debate, you might be someone who simply prefers not to ingest anything that escaped from a damaged nuclear reactor. If so, here’s what we know: Reverse Osmosis The EPA recommends reverse osmosis water treatment for most kinds of radioactive particles. Iodine-131 emits a small amount of gamma radiation but much larger amounts of beta radiation, and so is considered a beta emitter:
  • ...6 more annotations...
  • Reverse osmosis has been identified by EPA as a “best available technology” (BAT) and Small System Compliance Technology (SSCT) for uranium, radium, gross alpha, and beta particles and photon emitters. It can remove up to 99 percent of these radionuclides, as well as many other contaminants (e.g., arsenic, nitrate, and microbial contaminants). Reverse osmosis units can be automated and compact making them appropriate for small systems. via EPA, Radionuclides in Drinking Water
  • However, EPA designed its recommendations for the contaminants typically found in municipal water systems, so it doesn’t specify Iodine-131 by name. The same document goes on to say, “Reverse osmosis does not remove gaseous contaminants such as carbon dioxide and radon.” Iodine-131 escapes from damaged nuclear plants as a gas, and this is why it disperses so quickly through the atmosphere. It is captured as a gas in atmospheric water, falls to the earth in rain and enters the water supply.
  • Dissolved gases and materials that readily turn into gases also can easily pass through most reverse osmosis membranes,” according to the University of Nevada Cooperative Extension. For this reason, “many reverse osmosis units have an activated carbon unit to remove or reduce the concentration of most organic compounds.” Activated Carbon
  • That raises the next question: does activated carbon remove iodine-131? There is some evidence that it does. Scientists have used activated carbon to remove iodine-131 from the liquid fuel for nuclear solution reactors. And Carbon air filtration is used by employees of Perkin Elmer, a leading environmental monitoring and health safety firm, when they work with iodine-131 in closed quarters. At least one university has adopted Perkin Elmer’s procedures. Activated carbon works by absorbing contaminants, and fixing them, as water passes through it. It has a disadvantage, however: it eventually reaches a load capacity and ceases to absorb new contaminants.
  • Ion Exchange The EPA also recommends ion exchange for removing radioactive compounds from drinking water. The process used in water softeners, ion exchange removes contaminants when water passes through resins that contain sodium ions. The sodium ions readily exchange with contaminants.
  • Ion exchange is particularly recommended for removing Cesium-137, which has been found in rain samples in the U.S., but not yet in drinking water here. Some resins have been specifically designed for capturing Cesium-137, and ion exchange was used to clean up legacy nuclear waste from an old reactor at the Department of Energy’s Savannah River Site (pdf).

CPS must die [24Oct07} - 0 views

  • Collectively, Texas eats more energy than any other state, according to the U.S. Department of Energy. We’re fifth in the country when it comes to our per-capita energy intake — about 532 million British Thermal Units per year. A British Thermal Unit, or Btu, is like a little “bite” of energy. Imagine a wooden match burning and you’ve got a Btu on a stick. Of course, the consumption is with reason. Texas, home to a quarter of the U.S. domestic oil reserves, is also bulging with the second-highest population and a serious petrochemical industry. In recent years, we managed to turn ourselves into the country’s top producer of wind energy. Despite all the chest-thumping that goes on in these parts about those West Texas wind farms (hoist that foam finger!), we are still among the worst in how we use that energy. Though not technically “Southern,” Texans guzzle energy like true rednecks. Each of our homes use, on average, about 14,400 kilowatt hours per year, according to the U.S. Energy Information Administration. It doesn’t all have to do with the A/C, either. Arizonans, generally agreed to be sharing the heat, typically use about 12,000 kWh a year; New Mexicans cruise in at an annual 7,200 kWh. Don’t even get me started on California’s mere 6,000 kWh/year figure.
  • Let’s break down that kilowatt-hour thing. A watt is the energy of one candle burning down. (You didn’t put those matches away, did you?) A kilowatt is a thousand burnin’ candles. And a kilowatt hour? I think you can take it from there. We’re wide about the middle in Bexar, too. The average CPS customer used 1,538 kilowatt hours this June when the state average was 1,149 kWh, according to ERCOT. Compare that with Austin residents’ 1,175 kWh and San Marcos residents’ 1,130 kWh, and you start to see something is wrong. So, we’re wasteful. So what? For one, we can’t afford to be. Maybe back when James Dean was lusting under a fountain of crude we had if not reason, an excuse. But in the 1990s Texas became a net importer of energy for the first time. It’s become a habit, putting us behind the curve when it comes to preparing for that tightening energy crush. We all know what happens when growing demand meets an increasingly scarce resource … costs go up. As the pressure drop hits San Anto, there are exactly two ways forward. One is to build another massively expensive power plant. The other is to transform the whole frickin’ city into a de-facto power plant, where energy is used as efficiently as possible and blackouts simply don’t occur.
  • CPS has opted for the Super Honkin’ Utility model. Not only that — quivering on the brink of what could be a substantial efficiency program, CPS took a leap into our unflattering past when it announced it hopes to double our nuclear “portfolio” by building two new nuke plants in Matagorda County. The utility joined New Jersey-based NRG Energy in a permit application that could fracture an almost 30-year moratorium on nuclear power plant creation in the U.S.
  • ...17 more annotations...
  • CPS didn’t just pull nukes out of a hat when it went looking for energy options. CEO Milton Lee may be intellectually lazy, but he’s not stupid. Seeking to fulfill the cheap power mandate in San Antonio and beyond (CPS territory covers 1,566 square miles, reaching past Bexar County into Atascosa, Bandera, Comal, Guadalupe, Kendall, Medina, and Wilson counties), staff laid natural gas, coal, renewables and conservation, and nuclear side-by-side and proclaimed nukes triumphant. Coal is cheap upfront, but it’s helplessly foul; natural gas, approaching the price of whiskey, is out; and green solutions just aren’t ready, we’re told. The 42-member Nuclear Expansion Analysis Team, or NEAT, proclaimed “nuclear is the lowest overall risk considering possible costs and risks associated with it as compared to the alternatives.” Hear those crickets chirping?
  • NEAT members would hold more than a half-dozen closed-door meetings before the San Antonio City Council got a private briefing in September. When the CPS board assembled October 1 to vote the NRG partnership up or down, CPS executives had already joined the application pending with the U.S. Nuclear Regulatory Commission. A Supplemental Participation Agreement allowed NRG to move quickly in hopes of cashing in on federal incentives while giving San Antonio time to gather its thoughts. That proved not too difficult. Staff spoke of “overwhelming support” from the Citizen’s Advisory Board and easy relations with City staff. “So far, we haven’t seen any fatal flaws in our analysis,” said Mike Kotera, executive vice president of energy development for CPS. With boardmember and Mayor Phil Hardberger still in China inspecting things presumably Chinese, the vote was reset for October 29.
  • No one at the meeting asked about cost, though the board did request a month-by-month analysis of the fiasco that has been the South Texas Project 1&2 to be delivered at Monday’s meeting. When asked privately about cost, several CPS officers said they did not know what the plants would run, and the figure — if it were known — would not be public since it is the subject of contract negotiations. “We don’t know yet,” said Bob McCullough, director of CPS’s corporate communications. “We are not making the commitment to build the plant. We’re not sure at this point we really understand what it’s going to cost.” The $206 million outlay the board will consider on Monday is not to build the pair of 1,300-megawatt, Westinghouse Advanced Boiling Water Reactors. It is also not a contract to purchase power, McCullough said. It is merely to hold a place in line for that power.
  • It’s likely that we would come on a recurring basis back to the board to keep them apprised of where we are and also the decision of whether or not we think it makes sense for us to go forward,” said Larry Blaylock, director of CPS’s Nuclear Oversight & Development. So, at what point will the total cost of the new plants become transparent to taxpayers? CPS doesn’t have that answer. “At this point, it looks like in order to meet our load growth, nuclear looks like our lowest-risk choice and we think it’s worth spending some money to make sure we hold that place in line,” said Mark Werner, director of Energy Market Operations.
  • Another $10 million request for “other new nuclear project opportunities” will also come to the board Monday. That request summons to mind a March meeting between CPS officials and Exelon Energy reps, followed by a Spurs playoff game. Chicago-based Exelon, currently being sued in Illinois for allegedly releasing millions of gallons of radioactive wastewater beneath an Illinois plant, has its own nuclear ambitions for Texas. South Texas Project The White House champions nuclear, and strong tax breaks and subsidies await those early applicants. Whether CPS qualifies for those millions remains to be seen. We can only hope.
  • Consider, South Texas Project Plants 1&2, which send us almost 40 percent of our power, were supposed to cost $974 million. The final cost on that pair ended up at $5.5 billion. If the planned STP expansion follows the same inflationary trajectory, the price tag would wind up over $30 billion. Applications for the Matagorda County plants were first filed with the Atomic Energy Commission in 1974. Building began two years later. However, in 1983 there was still no plant, and Austin, a minority partner in the project, sued Houston Power & Lighting for mismanagement in an attempt to get out of the deal. (Though they tried to sell their share several years ago, the city of Austin remains a 16-percent partner, though they have chosen not to commit to current expansion plans).
  • After Unit 1 came online in 1988, it had to be shut down after water-pump shaft seared off in May, showering debris “all over the place,” according to Nucleonics Week. The next month two breakers failed during a test of backup power, leading to an explosion that sheared off a steam-generator pump and shot the shaft into the station yard. After the second unit went online the next year, there were a series of fires and failures leading to a half-million-dollar federal fine in 1993 against Houston Power. Then the plant went offline for 14 months. Not the glorious launch the partnership had hoped for. Today, CPS officials still do not know how much STP has cost the city, though they insist overall it has been a boon worth billions. “It’s not a cut-and-dried analysis. We’re doing what we can to try to put that in terms that someone could share and that’s a chore,” said spokesman McCollough. CPS has appealed numerous Open Records requests by the Current to the state Attorney General. The utility argues that despite being owned by the City they are not required to reveal, for instance, how much it may cost to build a plant or even how much pollution a plant generates, since the electricity market is a competitive field.
  • Even without good financial data, the Citizen’s Advisory Board has gone along with the plan for expansion. The board would be “pennywise and pound foolish” not to, since the city is already tied to STP 1&2, said at-large member Jeannie O’Sullivan. “Yes, in the past the board of CPS had been a little bit not as for taking on a [greater] percentage of nuclear power. I don’t know what their reasons were, I think probably they didn’t have a dialogue with a lot of different people,” O’Sullivan said.
  • A 2003 study at the Massachusetts Institute of Technology estimates the cost of nuclear power to exceed that of both coal and natural gas. A U.S. Energy Information Administration report last year found that will still be the case when and if new plants come online in the next decade. If ratepayers don’t pay going in with nuclear, they can bet on paying on the way out, when virtually the entire power plant must be disposed of as costly radioactive waste. The federal government’s inability to develop a repository for the tens of thousands of tons of nuclear waste means reactors across the country are storing spent fuel in onsite holding ponds. It is unclear if the waste’s lethality and tens of thousands of years of radioactivity were factored into NEAT’s glowing analysis.
  • The federal dump choice, Nevada’s Yucca Mountain, is expected to cost taxpayers more than $60 billion. If it opens, Yucca will be full by the time STP 3&4 are finished, requiring another federal dump and another trainload of greenbacks. Just the cost of Yucca’s fence would set you back. Add the price of replacing a chain-link fence around, let’s say, a 100-acre waste site. Now figure you’re gonna do that every 50 years for 10,000 years or more. Security guards cost extra. That is not to say that the city should skip back to the coal mine. Thankfully, we don’t need nukes or coal, according to the American Council for an Energy-Efficient Economy, a D.C.-based non-profit that champions energy efficiency. A collection of reports released this year argue that a combination of ramped-up efficiency programs, construction of numerous “combined heat and power” facilities, and installation of on-site renewable energy resources would allow the state to avoid building new power plants. Texas could save $73 billion in electric generation costs by spending $50 billion between now and 2023 on such programs, according to the research group. The group also claims the efficiency revolution would even be good for the economy, creating 38,300 jobs. If ACEEE is even mostly right, plans to start siphoning millions into a nuclear reservoir look none too inspired.
  • To jump tracks will take a major conversion experience inside CPS and City Hall, a turning from the traditional model of towering plants, reels of transmission line, and jillions of dependent consumers. CPS must “decentralize” itself, as cities as close as Austin and as far away as Seattle are doing. It’s not only economically responsible and environmentally sound, but it is the best way to protect our communities entering what is sure to be a harrowing century. Greening CPS CPS is grudgingly going greener. In 2004, a team of consultants, including Wisconsin-based KEMA Inc., hired to review CPS operations pegged the utility as a “a company in transition.” Executives interviewed didn’t understand efficiency as a business model. Even some managers tapped to implement conservation programs said such programs were about “appearing” concerned, according to KEMA’s findings.
  • While the review exposed some philosophical shortcomings, it also revealed for the first time how efficiency could transform San Antonio. It was technically possible, for instance, for CPS to cut electricity demand by 1,935 megawatts in 10 years through efficiency alone. While that would be accompanied with significant economic strain, a less-stressful scenario could still cut 1,220 megawatts in that period — eliminating 36 percent of 2014’s projected energy use. CPS’s current plans call for investing $96 million to achieve a 225-megawatt reduction by 2016. The utility plans to spend more than four times that much by 2012 upgrading pollution controls at the coal-fired J.T. Deely power plant.
  • In hopes of avoiding the construction of Spruce 2 (now being built, a marvel of cleanliness, we are assured), Citizen Oversight Committee members asked KEMA if it were possible to eliminate 500 megawatts from future demand through energy efficiency alone. KEMA reported back that, yes, indeed it was possible, but would represent an “extreme” operation and may have “unintended consequences.” Such an effort would require $620 million and include covering 90 percent of the cost of efficiency products for customers. But an interesting thing happens under such a model — the savings don’t end in 2012. They stretch on into the future. The 504 megawatts that never had to be generated in 2012 end up saving 62 new megawatts of generation in 2013 and another 53 megawatts in 2014. With a few tweaks on the efficiency model, not only can we avoid new plants, but a metaphorical flip of the switch can turn the entire city into one great big decentralized power generator.
  • How do we usher in this new utopia of decentralized power? First, we have to kill CPS and bury it — or the model it is run on, anyway. What we resurrect in its place must have sustainability as its cornerstone, meaning that the efficiency standards the City and the utility have been reaching for must be rapidly eclipsed. Not only are new plants not the solution, they actively misdirect needed dollars away from the answer. Whether we commit $500 million to build a new-fangled “clean-coal” power plant or choose to feed multiple billions into a nuclear quagmire, we’re eliminating the most plausible option we have: rapid decentralization.
  • For this, having a City-owned utility offers an amazing opportunity and gives us the flexibility to make most of the needed changes without state or federal backing. “Really, when you start looking, there is a lot more you can do at the local level,” said Neil Elliott of the ACEEE, “because you control building codes. You control zoning. You can control siting. You can make stuff happen at the local level that the state really doesn’t have that much control of.” One of the most empowering options for homeowners is homemade energy provided by a technology like solar. While CPS has expanded into the solar incentives field this year, making it only the second utility in the state to offer rebates on solar water heaters and rooftop panels, the incentives for those programs are limited. Likewise, the $400,000 CPS is investing at the Pearl Brewery in a joint solar “project” is nice as a white tiger at a truck stop, but what is truly needed is to heavily subsidize solar across the city to help kickstart a viable solar industry in the state. The tools of energy generation, as well as the efficient use of that energy, must be spread among the home and business owners.
  • Joel Serface, with bulb-polished pate and heavy gaze, refers to himself as a “product of the oil shock” who first discovered renewables at Texas Tech’s summer “geek camp.” The possibilities stayed with him through his days as a venture capitalist in Silicon Valley and eventually led him to Austin to head the nation’s first clean-energy incubation center. Serface made his pitch at a recent Solar San Antonio breakfast by contrasting Texas with those sun-worshipping Californians. Energy prices, he says, are “going up. They’re not going down again.” That fact makes alternative energies like solar, just starting to crack the 10-cent-per-killowatt barrier, financially viable. “The question we have to solve as an economy is, ‘Do we want to be a leader in that, or do we want to allow other countries [to outpace us] and buy this back from them?’” he asked.
  • To remain an energy leader, Texas must rapidly exploit solar. Already, we are fourth down the list when it comes not only to solar generation, but also patents issued and federal research awards. Not surprisingly, California is kicking silicon dust in our face.

Louisiana sinkhole, bubbles, 1000s quakes link to oil, gas ENMOD - National Human Right... - 0 views

  • On Monday, as officials warned an explosion is possible from gas in Louisiana’s sinkhole area where radioactive waste has been pumped into a cavern and the Department of Natural Resources (DNR) authorized drilling a new well in the danger sinkhole zone, a seismologist told the Examiner that seismic activity exists in that zone and that fossil fuel industries’ environmental modifications (ENMODs) causing the gas bubbles, giant sinkhole and thousands of quakes resulting in the State of Emergency, is a “real possibility.”
  • Seismic activity is being detected from Louisiana’s giant sinkhole area, according to Horton, whose work at University of Memphis involves monitoring the New Madrid fault line for the United States Geological Survey (USGS) as well as the Louisiana disaster.
