The Oil Drum | The Energy Return of Nuclear Power (EROI on the Web-Part 4) - 0 views

The seemingly most reliable information on EROI is quite old and is summarized in chapter 12 of Hall et al. (1986). Newer information tends to fall into the wildly optimistic camp (high EROI, e.g. 10:1 or more, sometimes wildly more) or the extremely pessimistic (low or even negative EROI) camp (Tyner et al. 1998, Tyner 2002, Fleay 2006 and Caldicamp 2006). One recent PhD analysis from Sweden undertook an emergy analysis (a kind of comprehensive energy analysis including all environmental inputs and quality corrections as per Howard Odum) and found an emergy return on emergy invested of 11:1 (with a high quality factor for electricity) but it was not possible to undertake an energy analysis from the data presented (Kindburg, 2007). Nevertheless that final number is similar to many of the older analyses when a quality correction is included. Figure 9. EROI for nuclear power plotted vs. year of analysis. (Source Robert Powers). Click to Enlarge. Tyner was the author (or co-author) on the 1988 and 1997 reports which are examples of the lower EROI numbers -- less than 5:1. Tyner’s 1997 paper reported an “optimistic value” of 3.84 and a “less-optimistic” value of 1.86 and may be based on “pessimistic” cost estimates.
Enron settlement goes to Battelle, Mid-Columbia utilities - Business | Tri-City Herald ... - 0 views

It's payback time for Enron's price gouging as millions of dollars from a settlement are being used to help homeowners and businesses, in part through a Battelle program in Richland. More than $9 million has been sent to programs that benefit Washington utility customers who were gouged by the manufactured energy crisis of 2000 to 2001, Washington Attorney General Rob McKenna announced Tuesday. Because of Enron's bankruptcy, not all of the $22.5 million owed to Washington was collected, but the $9 million was more than expected, he said.

US may have seen last new nuclear, coal plant: FERC's Wellinghoff - 0 views
-
He characterized the projected costs of new nuclear plants as prohibitive, citing estimates of roughly $7,000/kW.
-
In remarks focused on the promise of renewable energy and demand-side management, US Federal Energy Regulatory Commission Chairman Jon Wellinghoff on Wednesday suggested that there may never be another new nuclear or coal power plant built in the country. Pointing to upwards of 1,000 GW of potential wind energy in the Midwest and West, new solar power production and storage technologies and emerging hydrokinetic power resources, Wellinghoff asserted that renewables are poised to play a substantial, gap-filling role in the US energy picture.
New NRG nuclear plant to cost $10 billion | Reuters - 0 views
-
The cost to build a new nuclear power plant in Texas has risen to $10 billion, up from early estimates, but much below price tags of other proposed U.S. nuclear projects, an executive with NRG Energy Inc's nuclear development arm said on Tuesday. The "all in" cost to build two 1,350-megawatt nuclear reactors in South Texas has risen 40 percent from 2006 estimates which did not include financing costs, Steve Winn, chief executive of Nuclear Innovation North America (NINA), told the Reuters Global Energy Summit. While higher, NINA's current estimate is more than $10 billion under estimates from other nuclear developers that operate in states where regulators determine how much money utilities can charge customers for new power plants.
US chamber says 'green tape' stops 'thousands' of energy projects - 0 views

The US Chamber of Commerce on Thursday launched a campaign to promote "green projects" it said could proceed if only environmental groups, local governments and others would stop opposing sponsors' efforts to obtain sites and permits for the ventures. At a news conference at the chamber's Washington headquarters, officials said permitting and siting disputes, activist opposition and other "green tape" has killed or delayed "thousands" of coal, ethanol, natural gas, nuclear, transmission and wind projects.
Department of Energy - Locke, Chu Announce Significant Steps in Smart Grid Development - 0 views
-
U.S. Commerce Secretary Gary Locke and U.S. Energy Secretary Steven Chu today announced significant progress that will help expedite development of a nationwide "smart" electric power grid. A Smart Grid would replace the current, outdated system and employ real-time, two-way communication technologies to allow users to connect directly with power suppliers. The development of the grid will create jobs and spur the development of innovative products that can be exported. Once implemented, the Smart Grid is expected to save consumers money and reduce America's dependence on foreign oil by improving efficiency and spurring the use of renewable energy sources. Before it can be constructed, however, there needs to be agreement on standards for the devices that will connect the grid. After chairing a meeting of industry leaders at the White House, Locke and Chu announced the first set of standards that are needed for the interoperability and security of the Smart Grid and $10 million in Recovery Act funds provided by the Energy Department to the National Institute of Standards and Technology to support the development of interoperability standards.
Electricity costs should rise to reflect demand: Chu | Green Business | Reuters - 0 views
-
As the United States' power grid becomes more sophisticated, electricity rates will need to rise to reflect periods of intense energy use and to encourage consumers to change their electricity habits, U.S. Energy Secretary Steven Chu said on Monday. Chu said currently most local electricity rate commissions view themselves as consumer advocates and try to keep electricity prices as low as possible. "Hopefully that will evolve somewhat, so that they begin to fold in some of the real costs of electricity generation and electricity use," Chu said at conference focused on creating a "smart grid."
Letters: Renewables winning the energy race | Environment | The Guardian - 0 views

If I am travelling down an "irrational" road to renewables, as Richard Phillips implies (Letters, 11 September), then I am not alone. Last year, solar PV generation capacity grew by 70% around the world, wind power by 29% and solar hot water increased by 15%. By 2008, renewables represented more than 50% of total added generation capacity in both the US and Europe, ie more new renewables capacity was installed than new capacity for gas, coal, oil, and nuclear combined; with no emissions, no wastes and no security issues to worry about - and no worries about fuel running out, or increasing in price. It's true the energy available from some renewable sources, like wind, varies over time, but we already have to have backup capacity for other plants (including for nuclear plants), which is also used to deal with the daily energy demand peaks. With variable renewables on the grid, these backup plants have to be used a bit more often, adding a small extra cost and, if they are fossil-fuelled, reducing the amount of emissions saved very slightly. But hydro can also be used as backup, and increasingly, so can other types of non-variable renewable source, including biomass and geothermal energy.
The Great Beyond: Holdren meets the Brits - 0 views

John Holdren, science advisor to President Barack Obama, swung by Blighty today for some tea and crumpets with the Brits. But before embarking on a who's who tour of UK science policymakers, he joined the press in the basement of the US embassy for some all-American cookies and black coffee. Most of his hour-long round table was spent discussing climate change. He expressed some disappointment with the climate change legislation winding its way through the US Congress, but sees it as a make-or-break step for getting an effective international accord out of the UN's Copenhagen conference, which will take place in December. Some of the reporters expressed scepticism that a bill could be passed in time, but Holdren was optimistic, noting that the administration only needed around 12-15 additional votes in the Senate to pass the legislation. "I would still bet that it will happen, but I have to admit that it's going to be a challenge," he said.

In this remember-when photograph, a big crowd gathered on Nov. 4, 1963 to witness the shutdown of the historic Graphite Reactor at Oak Ridge. Note the relative dearth of women in the crowd. The Graphite Reactor, of course, was built during World War II as a prototype facilitiy for production of plutonium. It was the world's first continuously operated nuclear reactor and went critical for the first time in the pre-dawn hours of Nov. 4, 1943. The reactor operated for 20 years, contributing greatly to the nation's development of radioisotopes for medicine and other uses and for pioneering work with neutron-scattering experiments, etc.

Exelon plans nuclear unit uprates to add about 1,500 MW by 2017 - 0 views
-
Exelon has begun a series of nuclear power plant uprates that will add between 1,300 MW and 1,500 MW of generating capacity at its existing fleet of nuclear units over the next eight years, the company said Friday. The first of the uprates, totaling about 38 MW, was confirmed last week following upgrades at Exelon's Quad Cities plant near Cordova, Illinois. Uprate projects, some of which require US Nuclear Regulatory Commission approval, improve efficiency and increase electricity output of nuclear units through upgrades to plant equipment, Chicago-based Exelon said. The projects take advantage of new production and measurement technologies, new materials and experience from decades of nuclear power operations, the company said. Uprate efforts are underway at Exelon's Limerick and Peach Bottom nuclear plants in Pennsylvania, and the Dresden, LaSalle and Quad Cities plants in Illinois. Those are expected to produce nearly 25% of the added capacity. The remainder of capacity would come from uprates at nine other plants beginning in 2010 and ending in 2017.
US DOE to integrate nuclear power, waste programs: nominee - 0 views
-
US President Barack Obama's choice to head the Department of Energy's nuclear power programs told a Senate panel Tuesday that he would more closely integrate the development of new nuclear power and solving the problem of nuclear waste. "It is critical to take an integrated approach that considers the entire nuclear fuel cycle," Warren Miller told the Senate Energy and Natural Resources Committee during his confirmation hearing. Miller has been nominated as both assistant secretary of nuclear energy and the director of the Office of Civilian Radioactive Waste Management. During the previous administration, DOE staffed the positions with separate officials. Combining the two offices under one official comes as the administration moves to kill the controversial Yucca Mountain nuclear waste repository, which has long been planned for Nevada.
Report looks at hidden health costs of energy production - Politics AP - MiamiHerald.com - 0 views
-
Generating electricity by burning coal is responsible for about half of an estimated $120 billion in yearly costs from early deaths and health damages to thousands of Americans from the use of fossil fuels, a federal advisory group said Monday. A one-year study by the National Research Council looked at many costs of energy production and the use of fossil fuels that aren't reflected in the price of energy. The $120 billion sum was the cost to human health from U.S. electricity production, transportation and heating in 2005, the latest year with full data. The report also looks at other hidden costs from climate change, hazardous air pollutants such as mercury, harm to ecosystems and risks to national security, but it doesn't put a dollar value on them.

IEA says no emissions deal will double bills - Telegraph - 0 views
-
The independent body said the huge price of tackling climate change will eventually be overtaken by the cost of remaining dependent on fossil fuels, which are becoming more difficult and expensive to extract. It estimates that Europe's annual energy bill will more than double to $500bn (£300bn) by 2030, as the oil price is likely to reach $100 per barrel by 2015 and $190 by 2030. Publishing its annual World Energy Outlook, the IEA was also forced to defend its reputation as the world's leading provider of statistics on fossil fuels, following claims that it exaggerated oil resources under pressure from the US.

Brian Clark Howard: Close Aging Nukes By Installing LEDs - 4 views

"Remy Chevalier is a brilliant and eccentric eco-activist with a "bright plan": he believes a very achievable switchover to green lighting will save enough energy to shut down our aging nuclear power plants -- in particular Indian Point, one of the oldest and most controversial plants, and roughly 30 miles north of Manhattan. Seth Leitman and I found this out while working on our book about green lighting, to be published early this fall by the Green Guru Guide series. "
