IEA - December:- Coal's share of global energy mix to continue rising, with coal closin... - 0 views

  • Although the growth rate of coal slows from the breakneck pace of the last decade, global coal consumption by 2017 stands at 4.32 billion tonnes of oil equivalent (btoe), versus around 4.40 btoe for oil, based on IEA medium-term projections. The IEA expects that coal demand will increase in every region of the world except in the United States, where coal is being pushed out by natural gas.
  • “This report sees that trend continuing. In fact, the world will burn around 1.2 billion more tonnes of coal per year by 2017 compared to today – equivalent to the current coal consumption of Russia and the United States combined. Coal’s share of the global energy mix continues to grow each year, and if no changes are made to current policies, coal will catch oil within a decade.” 
  • The report notes that in the absence of a high carbon price, only fierce competition from low-priced gas can effectively reduce coal demand. “The US experience suggests that a more efficient gas market, marked by flexible pricing and fueled by indigenous unconventional resources that are produced sustainably, can reduce coal use, CO

  • As US coal demand declines, more US coal is going to Europe, where low CO2 prices and high gas prices are increasing the competitiveness of coal in the power generation system.

Coming Full Circle in Energy, to Nuclear - NYTimes.com - 0 views

  • In a typical day, Mr. Durgin tells me, 21 trains depart the mine, pulling 135 cars each. Each car bears 120 tons of coal. At this pace, he says, there is more than 20 years’ worth of coal ready to mine under my feet.
  • North Antelope Rochelle is among the biggest coal mines in the world. It produced 108 million tons last year — about 10 percent of all the coal burned by the nation’s power plants.
  • North Antelope Rochelle and the other vast strip mines cutting through the plains of Wyoming’s Powder River Basin — whose low-sulfur carbon met standards imposed by the Clean Air Act — were the result

  • Today renewable energy supplies only about 6 percent of American demand. And most of that comes from water flowing through dams. Solar energy contributes next to nothing.
  • The arithmetic is merciless. To make it likely that the world’s temperature will rise no more than 2 degrees Celsius above the average of the preindustrial era — a target agreed to by the world’s governments in 2010 — humanity must spew no more than 900 billion more tons of carbon dioxide into the air from now through 2050 and only 75 billion tons after that, according to an authoritative new study in Britain.
  • The United States Energy Information Administration forecasts that global energy consumption will grow 56 percent between now and 2040.
  • “We have trillions of tons of coal resources in the world,” Vic Svec, spokesman for Peabody Energy, told me. “You can expect the world to use them all.”
  • The only way around this is to put something in coal’s place, at a reasonably competitive price. Neither the warm glow of the sun nor the restless power of the wind is going to do the trick, at least not soon enough to make a difference in the battle to prevent climate change.

Tennessee Valley Authority to close 8 coal-fired power units - The Washington Post - 0 views

  • The Tennessee Valley Authority, one of the nation’s five biggest users of coal for electricity generation, said Thursday it would close down eight coal-fired power units with 3,300 megawatts of capacity.
  • Many of the plants were more than 50 years old, and under a consent decree between the TVA, four state governments and the Sierra Club, the authority was required to install additional pollution control equipment known as scrubbers or shut down the plants
  • Johnson said that electricity demand has dropped nearly 10 percent over the past five years., half of that because one company, USEC, which produced and sold enriched uranium for commercial nuclear power plants, ceased its energy-intensive operations.

What If We Never Run Out of Oil? - Charles C. Mann - The Atlantic - 0 views

  • In most cases, mining tar sands involves drilling two horizontal wells, one above the other, into the bitumen layer; injecting massive gouts of high-pressure steam and solvents into the top well, liquefying the bitumen; sucking up the melted bitumen as it drips into the sand around the lower well; and then refining the bitumen into “synthetic crude oil.”
  • Economists sometimes describe a fuel in terms of its energy return on energy invested (EROEI), a measure of how much energy must be used up to acquire, process, and deliver the fuel in a useful form. OPEC oil, for example, is typically estimated to have an EROEI of 12 to 18, which means that 12 to 18 barrels of oil are produced at the wellhead for every barrel of oil consumed during their production. In this calculation, tar sands look awful: they have an EROEI of 4 to 7. (Steaming out the bitumen also requires a lot of water. Environmentalists ask, with some justification, where it all is going to come from.)
  • To obtain shale gas, companies first dig wells that reach down thousands of feet. Then, with the absurd agility of anime characters, the drills wriggle sideways to bore thousands of feet more through methane-bearing shale. Once in place, the well injects high-pressure water into the stone, creating hairline cracks. The water is mixed with chemicals and “proppant,” particles of sand or ceramic that help keep the cracks open once they have formed. Gas trapped between layers of shale seeps past the proppant and rises through the well to be collected.

  • Water-assisted fracturing has been in use since the late 1940s, but it became “fracking” only recently, when it was married with horizontal drilling and the advanced sensing techniques that let it be used deep underground. Energy costs are surprisingly small; a Swiss-American research team calculated in 2011 that the average EROEI for fracked gas in a representative Pennsylvania county was about 87—about six times better than for Persian Gulf oil and 16 times better than for tar sands. (Fracking uses a lot of water, though, and activists charge that the chemicals contaminate underground water supplies.)
  • Today, a fifth of U.S. energy consumption is fueled by coal, mainly from Appalachia and the West, a long-term energy source that has provided jobs for millions, a century-old way of life
  • and pollution that kills more than 10,000 Americans a year (that estimate is from a 2010 National Research Council study).
  • Roughly speaking, burning coal produces twice as much carbon dioxide as burning the equivalent amount of natural gas. Almost all domestic coal is used to generate electricity—it produces 38 percent of the U.S. power supply. Fracking is swiftly changing this: in 2011, utilities reported plans to shut down 57 of the nation’s 1,287 coal-fired generators the following year. Largely in consequence, U.S. energy-related carbon-dioxide emissions have dropped to figures last seen in 1995. Since 2006, they have fallen more than those from any other nation in the world.
  • In the sort of development that irresistibly attracts descriptors like ironic, Germany, often touted as an environmental model for its commitment to solar and wind power, has expanded its use of coal, and as a result is steadily increasing its carbon-dioxide output. Unlike Americans, Europeans can’t readily switch to natural gas; Continental nations, which import most of their natural gas, agreed to long-term contracts that tie its price to the price of oil, now quite high.
  • Several researchers told me that the current towel-snapping between Beijing and Tokyo over islands in the East China Sea is due less to nationalistic posturing than to nearby petroleum deposits.)
  • In mid-March, Japan’s Chikyu test ended a week early, after sand got in the well mechanism. But by then the researchers had already retrieved about 4 million cubic feet of natural gas from methane hydrate, at double the expected rate.
  • What is known, says Timothy Collett, the energy-research director for the USGS program, is that some of the gulf’s more than 3,500 oil and gas wells are in gas-hydrate areas.
  • In Dutch-disease scenarios, oil weakens all the pillars but one—the petroleum industry, which bloats steroidally.
  • Because the national petroleum company, with its gush of oil revenues, is the center of national economic power, “the ruler typically puts a loyalist in charge,” says Michael Ross, a UCLA political scientist and the author of The Oil Curse (2012). “The possibilities for corruption are endless.” Governments dip into the oil kitty to reward friends and buy off enemies. Sometimes the money goes to simple bribes; in the early 1990s, hundreds of millions of euros from France’s state oil company, Elf Aquitaine, lined the pockets of businessmen and politicians at home and abroad.
  • How much of Venezuela’s oil wealth Hugo Chávez hijacked for his own political purposes is unknown, because his government stopped publishing the relevant income and expenditure figures. Similarly, Ross points out, Saddam Hussein allocated more than half the government’s funds to the Iraq National Oil Company; nobody has any idea what happened to the stash, though, because INOC never released a budget. (Saddam personally directed the nationalization of Iraqi oil in 1972, then leveraged his control of petroleum revenues to seize power from his rivals.)
  • “How will the royal family contain both the mullahs and the unemployed youth without a slush fund?”

Fear of Fracking by Jeffrey Frankel - Project Syndicate - 0 views

  • CAMBRIDGE – Against all expectations, US emissions of carbon dioxide into the atmosphere, since peaking in 2007, have fallen by 12% as of 2012, back to 1995 levels. The primary reason, in a word, is “fracking.”
  • Just ten years ago, the natural-gas industry was so sure that domestic production was reaching its limit that it made large investments in terminals to import liquefied natural gas (LNG). Yet fracking has increased supply so rapidly that these facilities are now being converted to export LNG.
  • Natural gas emits only half as much CO2 as coal, and occupies a rapidly increasing share of electricity generation – up 37% since 2007, while coal’s share has plummeted by 25%.

  • Meanwhile, the share of coal – the dirtiest fuel – has been rising, not falling, in the rest of the world’s energy mix.
  • Moving beyond economics, America’s reduction in net energy imports – which have already fallen by one-half since 2007 – means that its foreign policy will be less constrained by events in the Middle East. In Europe, the new technology could similarly break Russia’s politically troublesome stranglehold on natural-gas supplies.
  • Put differently, if the world continues to build coal-fired power plants at the current rate, those plants will still be around in 2050, regardless of what other technologies become viable in the meantime.
  • Even a serious fracking mishap would be unlikely to cause as much damage as the Deepwater Horizon oil spill in 2010, the Fukushima nuclear catastrophe in 2011, or coal-mining tragedies that play out dramatically in frequent explosions and collapses (and more insidiously in the form of lung disease, water pollution, and soil erosion).

What If We Never Run Out of Oil? - Charles C. Mann - The Atlantic - 1 views

  • Walking around town, my friend and I had noticed that almost every home had a pile of coal outside, soft dark chunks that people shoveled into stoves for cooking and heating. Thousands upon thousands of coal fires were loading the air with tiny dots of soot. Scientists have taken to calling these dots “black carbon,” and have steadily ratcheted up their assessments of its harm. In March, for instance, a research team led by a Mumbai environmental group estimated that black carbon and other particulate matter from India’s coal-fired power plants cause about 100,000 deaths a year.
  • A 31-scientist team from nine nations released a comprehensive, four-year assessment in January arguing that planetary black-carbon output is the second-biggest driver of anthropogenic (human-caused) climate change; the little black specks I found on my glasses and clothes have roughly two-thirds the impact of carbon dioxide.

  • Worse still, the aging natural-gas infrastructure is riddled with holes and seeps; early this year, a survey of gas mains along Boston’s 785 miles of road, the first-ever such examination, found 3,356 leaks.
  • What we can’t do, or at least not readily, is overcome the laws of economics.
  • To ask utilities to take in large amounts of solar power
  • One recent estimate put the EROEI of Spain’s extensive solar-power network at less than 3.
  • When renewables supply 20 to 30 percent of all electricity, many utility-energy engineers predict, the system will no longer be able to balance supply and demand. Brownouts will ripple across the landscape
  • As an example, typical solar cells today have an EROEI of about 10—better than tar sands but worse than most oil and gas.
  • is like asking a shipping firm to replace its huge, professionally staffed container ships with squadrons of canoes paddled by random adolescents.
  • But even if such techniques work in the way researchers hope, the infrastructure transformation ahead is daunting in scale and scope. It’s like setting up a second Industrial Revolution, only all over the world and in one-third the time.

  • It has also delayed new energy investments and is planning to close almost a quarter of its fossil fuel power plants,
  • European energy companies, struggling to respond to weak demand in a flatlining economy, say they need guaranteed pricing to keep open unprofitable plants or to invest in new ones.
  • Their revenue is being hit by dwindling demand for electricity and by new wind and solar projects that undercut the price of the energy produced from many fossil fuel plants.
  • At the same time, record-low prices on carbon emissions trading markets, which were introduced to encourage clean and efficient energy production and use, have perversely become a disincentive to investment.
  • Many of the Continent’s aging power stations, particularly those that burn highly polluting coal, are earmarked for closure by 2020 to meet stringent local environment regulations.
  • Without these investments, industrial companies in Europe may face higher energy prices when local economies eventually recover,
  • “Energy utilities are facing a perfect storm,”
  • In a bid to generate 20 percent of the European Union’s electricity from renewable sources by 2020, Germany, Spain and other E.U. countries have provided hefty subsidies to wind and solar farms, which now constitute a sizable minority of daily electricity generation, often surpassing the 20 percent target.

      In effect, a cheaper overall form of energy (non-renewables) had to compete with heavy subsidies to renewables, which, once built, had low operating costs.  They cannot compete and do not invest, and there are major problems w/investing more in renewables (they are overall more expensive, and they have built-in faults, producing electricity erratically, or during the wrong times.)  The high costs of energy also lie with government, who cemented long-term deals with the ex-USSR linking other energy prices to the price of oil.  In short, they shot themselves in the foot.  Several times.
  • Despite the upfront costs associated with green energy projects, they are inexpensive to run. In contrast, Europe’s gas and coal plants, which also provide backup power when renewables cannot operate, need constant spending on fossil fuels.
  • European utilities like E.On of Germany have announced plans to shut down less-polluting natural gas-fired plants that have been undercut by dirtier coal-burning generators benefiting from a flood of low-cost coal imports and low carbon emissions prices.
  • Policy makers are debating a system of support payments to keep uneconomic power plants open,
  • “Without long-term signals of energy prices, investment won’t happen.”

As Drilling Practice Takes Off in U.S., Europe Proves Hesitant - NYTimes.com - 0 views

  • Germany’s decision to eliminate its nuclear plants led it to bring coal-fired power plants out of mothballs to make up the difference. Doing so was a viable option because coal demand in the United States has dropped sharply as American power plants have turned to less expensive gas, driving down the cost of American coal for export to global markets.
  • As a result, carbon dioxide emissions in Germany went up last year, not down
  • “Without shale gas, this would be a world where Russia would have very, very strong market power and there would be very strong dependency on gas supply from geopolitically risky regions in the Middle East, Iran and North Africa,” said Laszlo Varro, the director of the Gas, Coal and Power Markets Division of the International Energy Agency.

  • Gazprom, the huge Russian gas company, finds its traditional business model in trouble. Under the pressure of a market in which gas is being supplied from more places, Gazprom has had to renegotiate gas contracts with European countries, costing it $6 billion, Mr. Varro said.
  • “Gazprom is not against shale gas,” Mr. Stevens said, “it’s just against everyone else having it.”

A Fracking Good Story by Bjørn Lomborg - Project Syndicate - 0 views

  • Carbon-dioxide emissions in the United States have dropped to their lowest level in 20 years.
  • this year’s expected CO2 emissions have declined by more than 800 million tons, or 14%, from their peak in 2007.
  • The cause is an unprecedented switch to natural gas, which emits 45% less carbon per energy unit. The US used to generate about half its electricity from coal, and roughly 20% from gas. Over the past five years, those numbers have changed, first slowly and now dramatically: in April of this year, coal’s share in power generation plummeted to just 32%, on par with gas.
  • ...6 more annotations...
  • For starters, fracking has caused gas prices to drop dramatically.
  • Indeed, US carbon emissions have dropped some 20% per capita, and are now at their lowest level since Dwight D. Eisenhower left the White House in 1961.
  • the shift from coal to natural gas has reduced US emissions by 400-500 megatonnes (Mt) of CO2 per year. To put that number in perspective, it is about twice the total effect of the Kyoto Protocol on carbon emissions in the rest of the world, including the European Union.
  • America’s 30,000 wind turbines reduce emissions by just one-tenth the amount that natural gas does. Biofuels reduce emissions by only ten Mt, and solar panels by a paltry three Mt.
  • Since 1990, the EU has heavily subsidized solar and wind energy at a cost of more than $20 billion annually. Yet its per capita CO2 emissions have fallen by less than half of the reduction achieved in the US – even in percentage terms, the US is now doing better.
  • Along with the closure of German nuclear power stations, this has led, ironically, to a resurgence of coal.
