4. Field Trip to a Power Plant

   

2006

28 December 2006. It's Free, Plentiful and Fickle. By MATTHEW L. WALD, NY Times. Excerpt: Wind, almost everybody's best hope for big supplies of clean, affordable electricity, is turning out to have complications. Engineers have cut the price of electricity derived from wind by about 80 percent in the last 20 years, setting up this renewable technology for a major share of the electricity market. But ...wind also ...is unpredictable and often fails to blow when electricity is most needed, ....power plants that run on coal or gas must "be built along with every megawatt of wind capacity," said William Bojorquez, director of system planning at the Electric Reliability Council of Texas. ... in Texas, and most of the United States, the hottest days are the least windy. ...A wind machine is a bit like a bicycle that a commuter keeps in the garage for sunny days. It saves gasoline, but the commuter has to own a car anyway.
...Frank P. Prager, managing director of environmental policy at [Xcel Energy], said ...that in one of the states the company serves, Colorado, if ...wind machines reach 20 percent of total generating capacity, the cost of standby generators will reach $8 a megawatt-hour of wind. That is on top of a generating cost of $50 or $60 a megawatt-hour, after including a federal tax credit of $18 a megawatt-hour. By contrast, electricity from a new coal plant currently costs in the range of $33 to $41 a megawatt-hour, according to experts. That price, however, would rise if the carbon dioxide produced in burning coal were taxed, a distinct possibility over the life of a new coal plant. (A megawatt-hour is the amount of power that a large hospital or a Super Wal-Mart would use in an hour.) Without major advances in ways to store large quantities of electricity ..., wind may run up against its practical limits sooner than expected. ...In May, Xcel and the Energy Department announced a research program to use surplus, off-peak electricity from wind to split water molecules into hydrogen and oxygen. ...But storage imposes a high cost: about half the energy put into the system is lost. The Electric Power Research Institute said that existing hydroelectric dams could be used as storage; they can increase and decrease their generation quickly, and each watt generated in a wind machine means water need not be run through the dam's turbines; it can be kept in storage, ready for use later, when it is most needed.
...the amount of energy that the average wind turbine produces over 12 months is equal to just 30 to 40 percent of the amount that would result from year-round operation at capacity. That number runs closer to 90 percent at a nuclear or coal plant. Thus a 1,000-megawatt nuclear plant will produce nearly three times as much electricity as 1,000 megawatts of wind turbines. But operating costs at the wind farm are lower, and the fuel is, of course, free.

[Comment from Alan Gould: the article does not explore possibility "distributed storage" i.e. each home (or neighborhood) having enough battery storage to get through cloudy/rainy/non-windy days. Distributed storage is the perfect match for distributed photovoltaic systems. Also, the article's figures about relative costs of wind and coal energy may have the classic flaw of not factoring in environmental costs for the coal energy.]

13 December 2006. Uranium Is a Hot Commodity, and Claims Have Soared. By FELICITY BARRINGER, NY Times. Excerpt: WASHINGTON, A fourfold increase in the price of uranium in the past three years has led to a rush of new claims by uranium companies, according to a new survey by an environmental group that wants to inform the public of potentially harmful consequences. Mining claim data compiled by the Environmental Working Group, Washington-based environmental research specialists, shows that, in Colorado, Utah, Wyoming and New Mexico, the total claims rose from just over 2,000 in 2001 to about 18,000 in 2005. ..."There's a renaissance of people's attitudes toward nuclear energy as a viable green, clean, clean-air type of energy sources," said Paul Matysek, president of the Vancouver-based firm Energy Metals Corporation. And, Mr. Matysek added, the increase in oil and natural-gas prices, even though they have eased in recent months, has spurred a mini-boom in the price of the metal.
"Three years ago it was $12 or $14" a pound, he said. "Today it's $65.50." ...Environmental groups said that ... the consequences could be severe. ...In Nevada, for instance, the environmental group's research found more than 166,000 new claims, covering more than 3.5 million acres of public land. ...only a tiny fraction of all claims - usually less than a tenth of one percent - are ever mined. But the scars of open-pit mining are visible in many places on the Environmental Working Group's Web site [http://www.ewg.org/], .... Still, said Mark Kuchta, an associate professor of mining engineering at the Colorado School of Mines, uranium mining in the future will have far less impact than the mines and the associated mills in the past. Increased cancer deaths have occurred near at least one old uranium mining sites. "The environmental laws have changed," Mr. Kuchta said. "In order to build the mine, there's a plethora of permits" needed. He added, "You can't just leave them on the surface and walk away the way you used to do."

12 December 2006. Buffalo: State Sues Over Nuclear Waste Site. By TIMOTHY WILLIAMS, NY Times. Excerpt: In a lawsuit filed yesterday against the federal government, the state is seeking payment for the cleanup of a former nuclear fuel reprocessing plant in western New York, state officials said. The lawsuit... asks the court to order the federal Department of Energy to pay for the disposal of what was originally 600,000 gallons of highly radioactive nuclear waste, said David Munro, an assistant attorney general. State officials estimate that the cost of disposing of the material at a planned federal waste depository will be $228 million....

7 November 2006. Committed to Coal, and in a Hurry, Too. By MATTHEW L. WALD. NY Times. Excerpt: FAIRFIELD, Tex. -
The TXU Corporation is embarking on its next monumental task: the nation's single largest coal-oriented construction campaign, with a plan to add more than 9,000 megawatts of new capacity, the equivalent of 3.5 percent of the nation's current coal-fired capacity. That is enough to power millions of homes. For people who want to limit global warming gases, the moves by TXU, which is based in Dallas, are a reminder that outside the laboratories and hearing rooms where scientists and policy makers talk about limiting carbon emissions, some power companies are racing to build infrastructure that will put carbon into the atmosphere into the middle of this century or longer. Whatever the cost to the ecosystem, it could be an immensely profitable bet. Company executives say the plants will provide cheap electricity for Texas, make lots of money for shareholders, conserve more valuable natural gas and reduce the pollutants that make smog. Texas has no goals for cutting carbon emissions. Nationally, the [energy] industry expects 19 percent growth over the next decade; in Texas, it is 25 percent. The state's peak electric demand grew 5 percent last summer, compared with the summer before.

15 September 2006 Clamping Down on Mercury Emissions BY DAN KROTZ, Lawrence Berkeley National Lab News.
Someday, those mercury warning labels posted near the fish section of supermarkets may join lead paint and asbestos as relics of a bygone era. Berkeley Lab scientists led by Shih-Ger (Ted) Chang have developed a potentially cheap and efficient way of removing mercury from coal-fired power plant emissions. ...As envisioned, his technique involves injecting a specially formulated gas into the mercury-laden flue gas of a coal-fired power plant, where it can convert elemental mercury into oxidized mercury, a form more easily captured by existing pollution control devices.
...The problem is also global. China's booming coal combustion industry emits more than 200 tons of mercury per year into the atmosphere, some of which drifts to the U.S.
Over time, some of the mercury released into the environment by power plants changes to methylmercury, which is a potent neurotoxin that is known to be detrimental to developing fetuses and young children. It is passed from prey to predator along the food chain, building up in certain types of fish and shellfish that people love to eat. In fact, methylmercury can accumulate in fish and marine mammals in concentrations hundreds of thousands times higher than the levels in surrounding waters, which is why state environmental regulatory agencies often issue fish consumption advisories....

9 September 2006. Interior Department Rejects Interim Plan for Nuclear Waste. By MARTIN STOLZ and MATTHEW L. WALD. NY Times. Excerpt: SKULL VALLEY, Utah, Sept. 8 - The Interior Department has moved to block a huge "interim" nuclear waste storage plant on an Indian reservation here, citing a lack of confidence that it would truly be temporary because there is so much doubt about completion of a permanent repository, at Yucca Mountain, Nev. ...The decision was hailed by many elected officials in Utah, which has no reactors, and where many non-Indians oppose the plan. But John D. Parkyn, the chairman of the board of Private Fuel Storage, the consortium, said in a telephone interview on Friday that the opinion about Yucca Mountain was contrary to federal policy and that there were various errors in the decision. One, Mr. Parkyn said, is that the decision said development on the reservation would require a tribal police force. But in fact, he said, the plant would have only about 20 employees, and most of those would be guards. If tribal police were somehow required, he said, the project would pay for them. ...The tribe is divided over the project. A proponent, Garth Jerry Bear, said Friday at his home on the reservation that the plant would provide hope for the desperately poor members, good-paying jobs and money for schools. ...Sammy Blackbear, an opponent of the storage plan, said he was elated by the decision.
"It should have come a long time ago,'' Mr. Blackbear said, "but this is better late than never."

September 2006. Winds of Change. Catalyst Magazine, Union of Concerned Scientists. By Jeff Deyette. Excerpt: ...The United States reached a wind energy milestone earlier this year: 10,000 megawatts (MW) of total generating capacity, or enough to power more than 2.5 million homes. ...Though the U.S. wind industry continues to expand at a rapid pace, the cost of developing a wind power project has actually increased over the past 18 months, in some cases significantly. The uncertainty of federal production incentives has deterred manufacturers from building assembly plants in the United States, requiring most turbines to be imported, and foreign-made turbines have become more expensive as the value of the U.S. dollar has fallen. At the same time, high global demand has caused most turbine manufacturers to sell out through 2008, and the cost of steel and other materials has risen sharply due mostly to higher fossil fuel prices. Other factors include the difficulties associated with using more sophisticated electronic components and increased profit margins by manufacturers.
Fortunately, none of these obstacles are insurmountable. Higher fossil fuel prices have driven up the cost of conventional power generation, enabling wind power to remain cost-competitive.
...Two exciting new technologies hold out the promise of consistent growth for the wind industry in the coming decades: turbines that can be set in deep offshore waters, and land-based turbines that can operate cost-effectively at lower wind speeds....

6 August 2006. Physics Today - LETTERS - Tough questions about wind energy Excerpts: Kenneth Perry - Boulder, Wyoming: In suggesting that the US should turn to wind-generated electric power (see PHYSICS TODAY, July 2005, page 34), Cristina Archer and Mark Jacobson fail to discuss the visual impact of wind farms.... Terry Goldman, Los Alamos, New Mexico:
As a free-standing, reliable, and stable source of energy, wind power is totally inadequate; even as a secondary, supportive source, it has serious limitations. Due to the character of wind, power is not produced in a steady stream over a long period but in a succession of spikes between zero and full power. The fluctuation makes reliable management of the power grid very risky. Moreover, wind power generation delivers only a modest fraction (20% to 25%) of the installed power capacity....
Archer and Jacobson comment: Kenneth Perry suggests that wind turbines interfere with nature's beauty. We believe, though, that the correct comparison is not with nature's beauty but with the visual, health, and climate impacts of coal, natural gas, and nuclear power plants (see, for example, http://www.fotosearch.com/photos-images/coal-burning-plant.html), which is what wind turbines would be replacing. ...Frits de Wette contends that the intermittency of wind makes power management of a wind-energy-dominated grid risky. This is true when wind farms are not linked together in an organized manner through the transmission grid, but not true if they are. We have shown in a new study that interconnecting up to 19 wind farms several hundred kilometers apart converts an intermittent wind resource to one that produces about one-third of its electric power at the same reliability as the average US coal-fired power plant-which has a 12.5% outage rate. Remaining electricity can be firmed with hydroelectric, geothermal, solar, or other power. The website for Red Elˇctrica, which operates Spain's electric power system (http://www.ree.es/ingles/i-index_de.html), further shows, as an example, that linking most of Spain's wind farms through a common grid would eliminate minute-by-minute fluctuations that occur at a single wind farm.
...Terry Goldman suggests that large-scale wind farming will cause significant bird loss. Statistics suggest otherwise. According to the Bird Conservancy, the 15 000 existing US wind turbines kill 10 000 to 40 000 birds per year, which compares with 50 million US bird deaths per year due to transmission towers and 200 million worldwide due to avian flu in 2005. Extrapolating to 5 million 5-MW turbines needed to satisfy all electric power and energy needs worldwide gives 3 million to 13 million bird deaths per year, much less than transmission towers in the US alone. -Cristina Archer

9 August 2006. Nevada Loses Decision on Atomic Waste
By THE ASSOCIATED PRESS. Excerpt: Nevada was set back in its effort to avoid housing a radioactive waste dump as a federal appeals court rejected arguments against transportation plans. Nevada had said that the Energy Department overstepped its authority and violated environmental rules in deciding to rely mostly on trains to carry 77,000 tons of spent nuclear fuel from around the country to Yucca Mountain. "We conclude that some of Nevada's claims are unripe for review, and the remaining claims are without merit," said a decision written by Judge Karen LeCraft Henderson for a three-judge panel of the United States Court of Appeals for the District of Columbia Circuit.

1 August 2006. LEBANESE OIL SLICK - UN Warns of Environmental Disaster - Spiegel Online - Excerpt: While the war rages on, a huge environmental disaster is threatening Lebanon's coast. Up to 35,000 tons of oil have spilled into the Mediterranean following Israeli air strikes -- now it is a race against time to prevent long-term damage and the destruction of a fragile ecosystem. The Lebanese government is calling it the biggest ecological catastrophe in the country's history. Between July 13 and 15, Israeli jets bombed the Jiyyeh power station, located 30 kilometers south of Beirut, and caused up to 35,000 tons of fuel oil to gush into the sea. The oil slick has now spread along 80 kilometers of Lebanon's 225 kilometer coastline and has already reached Syria. A clean up operation is badly needed, but continuing hostilities between the Israeli army and Hezbollah have made this virtually impossible. Now, the catastrophe is threatening to damage the environment across many parts of the Mediterranean. ...As bad as the Exxon Valdez?
In an interview with the BBC, the ministry's director general, Berj Hatjian, compared the oil slick to that caused by the Exxon Valdez tanker, "with 20,000 to 30,000 tons reaching the shoreline." When the tanker sank off the coast of Alaska in 1989, 40,000 tons of oil were released into the sea. The result was the worst ever maritime environmental disaster. Hundreds of thousands of animals died, and because the oil spill could not be completely cleaned up animals are still being poisoned today. The environmental impact of the current oil slick is not confined to Lebanon and risks spreading through the Mediterranean. The Regional Marine Pollution Emergency Response Center (Rempec), based in Malta, has already recorded the first traces of oil on the Syrian coast -- confirming reports of contamination made by the port authority at Syria's coastal town of Tartus....

16 July 2006. Atomic Balm? A Nuclear Renaissance? By JON GERTNER. NY Times. Excerpt: ... the Alvin W. Vogtle nuclear-power generating station... (pronounced VOH-gull) was being built in the 1970's and 80's, it ... was one of the largest construction projects in the history of Georgia. ...its total cost, $8.87 billion, was so far overbudget that Vogtle became yet another notorious example of the evils of nuclear energy. In the public mind, the issue was safety. For the industry, the larger concern was economics. ...Vogtle was intended to generate a total of around 4,500 megawatts of electricity, enough power to serve the needs of several million homes. The grand plan was to have four reactors. Instead, it was scaled back to two, .... Today these reactors together produce about 2,400 megawatts, satisfying about 15 percent of the state's power needs.

June 2006. (from the ASEE International Engineering Education Digest). Nuclear power revival - Political interest in nuclear power is reviving across the world, thanks in part to concerns about global warming and energy security. Currently some 441 commercial reactors operate in 31 countries and provide 17% of the planet's electricity, according to a US Department of Energy report cited in the June 3rd The Economist. Until recently the talk was of how to retire these reactors gracefully, but now it is of how to extend their lives. And in addition another 32 reactors are being built, mostly in India, China and their neighbors. The new 'third generation' reactors are considered by their creators to be safer than their predecessors. Further into the future, engineers are developing designs for so-called 'fourth generation' plants that could be built between 2030 and 2040. Work on these designs is being undertaken by a ten-nation research program whose members include the US, Britain, China, France, Japan, South Africa and South Korea. (See http://www.economist.com)

20 June 2006. THE ENERGY CHALLENGE. Europe's Image Clashes With Reliance on Coal. By MARK LANDLER - NY Times. Excerpt: SCHWARZE PUMPE, Germany - In the shadow of two hulking boilers, which spew 10 million tons of carbon dioxide a year into the air, the Swedish owners of this coal-fired power station recently broke ground on what is to be the world's first carbon-free plant fueled by coal. The German chancellor, Angela Merkel, presided over the ceremony. ..."We accept the problem of climate change," said Reinhardt Hassa, a senior executive at Vattenfall, which operates the plant. "If we want a future for coal, we have to adopt new technologies. It is not enough just to make incremental improvements." But the new plant, which will be just a demonstration model, pales next to the eight coal-fired power stations Germany plans to build for commercial use between from now to 2011 - none of them carbon-free. "That is really a disappointing track record," said Stephan Singer, the director of climate and energy policy at the World Wide Fund for Nature in Brussels. "Just replacing old coal plants with new coal plants won't enable Germany to meet stricter carbon emission targets." ...The recent spike in the price of oil has thrown the spotlight back on coal, even in places like Britain, where the industry had been in a death spiral for decades. Richard Budge, a longtime British coal executive, ...noted [...coal] is not a hostage to politics. When Russia abruptly switched off its natural gas pipeline to Ukraine in January over a pricing dispute, gas supplies dwindled all over Western Europe. ..."Fifty-eight percent of the world's gas is owned by Russia, Iran and Qatar," Mr. Budge said. "Coal is on every continent." ... in eastern Germany, ...So great is the demand that the government allows companies to forcibly resettle villages that lie in the path of their excavators. The process is costly and litigious and can take more than a decade....

14 June 2006. Ontario Revives Nuclear Power Plan By IAN AUSTEN. NY Times. Excerpt: OTTAWA, June 13 - In an effort to revive a nuclear energy program that has been marred by billions of dollars in debt, cost overruns and disappointing performance, the province of Ontario on Tuesday announced a plan to spend about 20 billion Canadian dollars ($18 billion [US]) to build reactors and refurbish some current units.
The plan also includes about 20 billion Canadian dollars for renewable energy projects and 6 billion Canadian dollars ($5.3 billion) for power conservation. ...Vaughan Gilbert, a spokesman for Westinghouse Nuclear, which is based in Monroeville, Pa., and owned by BNFL of Britain, said, "We've been gearing up for this even though the market for new plants in North America had dried up." If completed as envisioned, the plan will maintain the current level of nuclear-generated power, which provides about half of Ontario's electricity. The other half is provided mainly by hydro-electric dams and coal. ...3 of Ontario's 19 reactors are not in use.
A Conservative government that preceded Mr. Duncan and the Liberals restructured the province's government-owned electrical system as a prelude to privatization. But a variety of problems, including a political scandal tied to utility executives' salaries, meant that the province never saw a major influx of privately owned power-generating companies.
Those issues recently forced Mr. Duncan to back away from a campaign pledge to close by 2009 the coal-fired generating stations. ...The project will initially involve at least two units at a cost of about 2 billion Canadian dollars each. ...Mark Winfield, the director of environmental governance at the Pembina Institute for Appropriate Development, predicted that the province would only experience further financial grief by recommitting to nuclear generation. "It's a very strange approach and a very high-risk one as well," he said. Mr. Winfield said he was skeptical that nuclear power generation would succeed financially this time around, and said the government was underestimating the full potential of energy conservation.

11 June 2006. THE ENERGY CHALLENGE. Pollution From Chinese Coal Casts a Global Shadow. By KEITH BRADSHER and DAVID BARBOZA. NY Times. Excerpt: HANJING, China - One of China's lesser-known exports is a dangerous brew of soot, toxic chemicals and climate-changing gases from the smokestacks of coal-burning power plants. In early April, a dense cloud of pollutants over Northern China sailed to nearby Seoul, sweeping along dust and desert sand before wafting across the Pacific. An American satellite spotted the cloud as it crossed the West Coast. Researchers in California, Oregon and Washington noticed specks of sulfur compounds, carbon and other byproducts of coal combustion coating the silvery surfaces of their mountaintop detectors. These microscopic particles can work their way deep into the lungs, contributing to respiratory damage, heart disease and cancer. Filters near Lake Tahoe in the mountains of eastern California "are the darkest that we've seen" outside smoggy urban areas, said Steven S. Cliff, an atmospheric scientist at the University of California at Davis.
Unless China finds a way to clean up its coal plants and the thousands of factories that burn coal, pollution will soar both at home and abroad. The increase in global-warming gases from China's coal use will probably exceed that for all industrialized countries combined over the next 25 years, surpassing by five times the reduction in such emissions that the Kyoto Protocol seeks.... Coal is indeed China's double-edged sword - the new economy's black gold and the fragile environment's dark cloud. Already, China uses more coal than the United States, the European Union and Japan combined. ...Every week to 10 days, another coal-fired power plant opens somewhere in China that is big enough to serve all the households in Dallas or San Diego. To make matters worse, India is right behind China in stepping up its construction of coal-fired power plants - and has a population expected to outstrip China's by 2030. ...Two years ago, Datong, long the nation's coal capital, was branded one of the world's most-polluted cities. Since then, the air quality has only grown worse. Datong is so bad that last winter the city's air quality monitors went on red alert. Desert dust and particulate matter in the city had been known to force the pollution index into warning territory, above 300, which means people should stay indoors.
On Dec. 28, the index hit 350. ...The Chinese are still far from achieving what has become the basic standard in the West. Urban elites who can afford condominiums are still a tiny fraction of China's population. But these urban elites are role models with a lifestyle sought by hundreds of millions of Chinese. Plush condos on sale in Shanghai are just a step toward an Americanized lifestyle that is becoming possible in the nation's showcase city....

 

28 May 2006. Industry Leaders Bet on Coal but Split on Cleaner Approach. By SIMON ROMERO. NY Times. Excerpt: WRIGHT, Wyo. - More than a century ago a blustery Wyoming politician named Fenimore Chatterton boasted that his state alone had enough coal to "weld every tie that binds, drive every wheel, change the North Pole into a tropical region, or smelt all hell!"...His words seem prophetic. The future for American energy users is playing out in coal-rich areas like northeastern Wyoming, where dump trucks and bulldozers swarm around 80-foot-thick seams at a Peabody Energy strip mine here, one of the largest in the world. Coal, the nation's favorite fuel in much of the 19th century and early 20th century, could become so again in the 21st. The United States has enough to last at least two centuries at current use rates - reserves far greater than those of oil or natural gas. ... The decisions being made right now in industry and government on how quickly to adopt any new but more costly technologies will be monumental. "Coal isn't going away, so you have to think ahead," said Gavin A. Schmidt, a climate modeler at the Goddard Institute for Space Studies, part of NASA. "Many of these power stations are built to last 50 years." ...Gregory Boyce... was chairman of an advisory panel for the Energy Department, organized by the National Coal Council, that produced a controversial report in March calling for exemptions to the Clean Air Act to encourage greater consumption of coal through 2025. The thrust of the report, which Mr. Boyce outlined in an interview, is that improvements in technology to limit carbon dioxide emissions should be left to the market instead of government regulation. ...Led by Peabody, dozens of energy companies have embarked on the most ambitious construction of coal-fired electricity plants since the 1950's. ...While Peabody supports some coal gasification projects, it remains skeptical about departing from traditional coal-burning methods to produce electricity. The pulverized coal plants it wants to build, which grind coal into a dust before burning it to make electricity, currently cost about $2 billion each, or 15 percent to 20 percent less to build than the cleaner "integrated gasification combined cycle," or I.G.C.C., plants, which convert coal into a gas. ...Engineers have known how to make gas from coal for more than a century, using this method in the gaslights that first illuminated many American cities. A handful of coal gasification plants are already in operation in the United States, Spain and the Netherlands, ...As they proceed with plans to build pulverized coal plants, Peabody and other companies often point to their support of the alternative technology through their participation in Futuregen, a $1 billion project started three years ago by the Bush administration to build a showcase 275-megawatt power station that could sequester carbon dioxide and reduce other pollutants....

13 May 2006. U.N. Finds New Uranium Traces in Iran. By WILLIAM J. BROAD. NYTimes. Exceprt: Atomic inspectors have found traces of highly enriched uranium on equipment linked to an Iranian military base, raising new questions about whether Iran harbors a clandestine program to make nuclear bombs, diplomats said yesterday. It is the second such discovery in three years of United Nations inspections in Iran. As the Security Council debates how to handle the atomic impasse with Tehran, the finding is likely to deepen skepticism about Iran's claims that its program is entirely peaceful...."There are still lots of questions," a senior European diplomat said. "So it's not a smoking gun." ...Highly enriched uranium contains 20 percent or more of a rare form of uranium, known as its 235 isotope. Bomb-grade uranium is usually defined as 80 percent or more, and can be fashioned into the core of a nuclear weapon. The bomb dropped on Hiroshima contained 140 pounds of highly enriched uranium. The senior European diplomat said the samples from Iran indicated the presence of highly enriched, but not necessarily bomb-grade, uranium. Iran says its atomic program is meant to enrich uranium to the relatively low grades needed for the production of electrical power in nuclear reactors, about 3 or 4 percent, a level that the inspectors recently confirmed. ...

May 2006. Energy Secretary Sends Yucca Legislation to Congress. Physics Today, page 25. Jim Dawson. Yucca Mountain, Nevada. Excerpt: Some 20 years and $8.6 billion after Yucca Mountain in Nevada was first rated by the US Department of Energy as the best site in the country to permanently store tens of thousands of tons of high-level nuclear waste, the Bush administration is beginning a new push to get the languishing project moving. But the new initiative, a legislative proposal DOE Secretary Samuel Bodman sent to Congress in early April, faces a difficult time on Capitol Hill. ...In a letter to the Senate and House that accompanied the legislative proposal, Bodman said the "existence of a repository at Yucca Mountain is critical to the expanded use of nuclear power." Even with the administration's new proposal for a global nuclear energy partnership, which focuses on recycling nuclear waste instead of storing it, Bodman said the Yucca repository "will continue to be necessary to deal with the spent nuclear fuel and high-level radioactive waste that will be generated by those [recycling] technologies." Currently about 55 000 metric tons of spent nuclear fuel and high-level radioactive waste are stored at more than 100 sites in 39 states, according to DOE officials. An additional 2000 metric tons of high-level nuclear waste is being generated each year. The proposed legislation calls for several specific actions by Congress to make the development of the Yucca site possible. DOE asks that 147 000 acres of land surrounding Yucca Mountain, which is located about 90 miles northwest of Las Vegas, be withdrawn from public use. Possession of the land by DOE is one of the NRC requirements for granting a license to build the facility. The legislation would also repeal the 70 000-metric-ton capacity limitation for waste storage at the facility and allow the limit to "be determined by the actual physical capacity of the mountain." ... the US Environmental Protection Agency is expected to announce in the next several months a new standard for limiting radiation exposure at the Yucca repository for a one-million-year period. The revised standard is needed since the previous standard, based on the repository's being safe for 10 000 years, was thrown out in 2004 by the US Court of Appeals in the District of Columbia because it was not "based on and consistent with" an earlier National Academy of Sciences radiation peak-dose safety recommendation....

27 April 2006. G.E., Betting on the Future, Finances a Solar Farm in Portugal. By CLAUDIA H. DEUTSCH , NY Times. Excerpt: Next month the PowerLight Corporation, using $75 million of the General Electric Company's money, will begin installing the first of what will be 52,000 solar panels, capable of generating 11 megawatts of electricity - enough to light and heat 8,000 homes. ..."It takes a huge amount of work to develop these projects, to get the permits, to find the modules, and solar energy still costs more than fossil fuels or wind," Mr. Marsden said. "So we are only going to invest in countries with supportive regimes." That list does not yet include the United States. Richard King, a team leader in the Energy Department's photovoltaic research group, said that many homeowners, particularly in California, had installed rooftop panels, as had some Wal-Mart stores and other businesses. But Mr. King conceded that American economics did not yet favor solar energy. He said that people in Portugal and many other parts of Europe were already accustomed to paying 25 cents to 30 cents a kilowatt hour for electricity. In the United States, the cost still averages 10 cents to 14 cents, "and utilities are just not going to buy 25-cent solar electricity," he said.

January 2006. Rush to Bury High-Level Nuclear Waste Ignores Flaws of Yucca Mountain Site. PSR Reports - Physicians for Social Responsibility http://www.psr.org. In its annual budget for fiscal year (FY) 2007, the Department of Energy (DOE) requested $544.5 million in new spending for the proposed high-level nuclear waste storage facility in the Yucca Mountain range near Las Vegas, Nevada. This request reflects an almost $100 million increase in spending on Yucca mountain from the $450 million that Congress appropriated for FY 2006. ...U.S. nuclear power plants have already generated more than 40,000 tons of high-level waste (a small portion of this is a byproduct of U.S. nuclear weapons production activities). This highly lethal stockpile is currently stored around the country at commercial and government facilities, and it continues to grow rapidly, as current nuclear power production adds 2,000 tons of waste to the existing pile every year. Industry pressure for a solution is mounting; the federal government was scheduled to assume responsibility for this waste nearly a decade ago. If DOE fails to move the waste to a federal repository, power plants that run out of on-site storage space will be forced to shut down. ...in April 2005, Energy Secretary Samuel Bodman publicly acknowledged that water flow and quality assurance data for the Yucca Mountain site could have been falsified. DOE's own investigation and Congressional inquiries into United States Geological Service computer modeling of climate and water infiltration at the site uncovered numerous e-mail exchanges, dating back to 1998 and 2000, in which government scientists discussed fabricating documentation for a key scientific study about ground water penetration into the repository and admitted they made up data.

January 2006. Last year, the state of Colorado implemented incentives for promoting alternative, sustainable sources for electrical power to Colorado customers. The Xcel Energy company is electricity provider that makes the Windsource program (accredited by the Green-e Renewable Energy Program) available to customers who chose to pay slightly more for electricity in order to encourage wind powered electricity. The following text appeared on a web page for Xcel Energy:
"Based on the electric rates effective January 1, 2006, and monthly average usage of 625 kilowatt-hours (kWh), the following table shows what typical Xcel Energy Colorado residential customers would pay for monthly electricity service to purchase 500 kWh per month of Windsource.... The Windsource Adjustment may be slightly higher for commercial & industrial customers.

  Residential rates effective January 1, 2006
 Monthly electricity cost  $59.35
 Windsource Adjustment (five 100 kWh blocks @ $0.072 credit/block)  ($0.36)
 Total  $58.99

Note that the "Adjustment" is in parentheses, indicating negative quantity, meaning that the cost of wind energy is now LESS than the cost of other energy sources, in particular, fossil fuel sources. There is now a waiting list for the Windsource program in Colorado. We could view this as a watershed moment in the history of electrical energy production: as fossil fuel costs continue to increase in ever accelerating fashion, costs of alternative electrical energy production does not increase nearly fast. We knew that inevitably, alternative sustainable energy sources would be cheaper than fossil fuel sources. We just did not know how soon that would happen. But as the Colorado situation shows, it's happening sooner than some people expected. Next milestone to look for: when cost of photovoltaic (solar) electricity undercuts cost of fossil fuel electricity cost... ---Alan Gould
