The Altamont is the world's oldest wind farm with some 5,000 power-generating turbines covering 50 square miles on the Alameda County border. While generating good green power for the state, it has a bad reputation for killing birds. The wind turbines on the gusty Altamont Pass were installed after the energy crisis in the 1970s. Today, the world's oldest wind farm powers an average of 100,000 homes with clean green energy. But environmentalists say it comes at a steep price.

Six California renewable energy facilities proposed by AES Corp. (AES), FPL Group Inc. (FPL), BrightSource Energy Inc. and Germany's Solar Millennium (S2M.XE) are being fast-tracked for government permits needed to start construction, a federal official said Thursday. Together, the renewable power plants would generate nearly 2,500 megawatts of electricity, and occupy more than 28,000 acres of land, said U.S. Interior Secretary Ken Salazar. ...To be eligible for federal stimulus funds renewable energy developers must begin construction by December 2010.

Texas cares little for environmental niceties. Its governor, Rick Perry, bashes the Environmental Protection Agency at every opportunity, and recently branded the climate bill that passed the House of Representatives a "legislative monstrosity." Yet the oil-and-gas state has nonetheless emerged as the nation's top producer of a commodity prized by environmentalists: wind power. Eager developers are covering its desolate western mesas with giant turbines. The world's largest wind farm began operations in Texas this month, and the state now has close to three times as much wind capacity as Iowa, the second-ranked state.

The announcement ended a long-running dispute between backers of renewable energy and environmentalists ...The acrimony even triggered a nasty public squabble between Robert Kennedy Jr., a senior adviser at VantagePoint Venture Partners, which raised $160 million for BrightSource, and David Myers, executive director of the Wildlands Conservancy, which raised $40 million to buy the railroad lands and protect them from development.

Despite the hoopla over renewable energy - media chatter, government rebates, neighbors who "go green" - the nuts and bolts of installing more Earth-friendly power sources often get stuck. San Diego County, for example, is wrestling with how to handle applications for using residential wind turbines. Critics say the approval process is confusing and drawn-out enough to discourage investment in green power, just as companies are moving to fill the home-windmill niche.

The intent to prevent California's utilities from using out-of-state wind and solar generation to meet the new 33% RPS requirement is not obvious from the provisions of the bills. The exclusion results from a change in the requirements concerning the "delivery" of generation to California. Under California's current RPS legislation, in order to qualify as an eligible renewable energy resource such that California's utilities can count that generation against their RPS requirements, out-of-state generators are required to deliver the electricity to California simultaneous with its generation.

While President Obama has made development of cleaner energy sources a priority, an effort is underway to close off a large swath of the Southern California desert to solar and wind energy projects. In a move that could pit environmentalists and alternative energy industries against each other, the senator wants hundreds of thousands of acres in California designated as a national monument.

To his chagrin, some of Mr. Myers's fellow environmentalists are helping power companies pinpoint the best sites for solar-power technology. The goal of his former allies is to combat climate change by harnessing the desert's solar-rich terrain, reducing the region's reliance on carbon-emitting fuels. Mr. Myers is indignant. "How can you say you're going to blade off hundreds of thousands of acres of earth to preserve the Earth?" he said. As the Obama administration puts development of geothermal, wind and solar power on a fast track, the environmental movement finds itself torn between fighting climate change and a passion for saving special places.

As wind power becomes more common, its unpredictability becomes more of a problem. Sudden drops in wind speed can send grid operators scrambling to cover the shortfall and even cause blackouts; unexpected surges can leave conventional power plants idling, incurring costs and spewing pollution to no purpose. ...When wind farms were less common, grid controllers could essentially ignore their varying output, as it was all but indistinguishable from natural fluctuations in consumer use.

Looking east into Gilliam County and north into Washington, turbines are strung over ridgelines as far as the eye can see. And there are nowhere near enough of them. ...West Coast utilities and independent power producers are locked in a land rush to secure the best wind sites and the power they produce. Coupled with a worldwide shortage of turbines and a falling dollar, the resulting scarcity is driving up the cost of wind power, a burden electricity ratepayers will shoulder.

Like any industry worth its lobbyists, Silicon Valley pushes hard for the legislation it wants. And this year, it wants a new federal energy law. A climate change law, too.

A San Rafael wind turbine maker has secured financial backing to establish manufacturing operations with the help of a "significant" investment from Goldman Sachs & Co., one of the world's largest investment banks, the company announced Monday. Formed about three years ago, Nordic Windpower Inc. is preparing to start domestic production of its two-bladed, utility-scale wind turbines for sale to small and large energy producers.

The United States is expected to be home to an anticipated 49,000 MW of installed wind-power capacity by 2015, making it the world's largest wind-power producer, according to a recent report. Developers are expected to invest more than $65 billion between 2007 and 2015 in wind-power facilities, researchers say.

WASHINGTON - The House rejected a resolution Wednesday that would block government plans to spur construction of major new power lines in many states regardless of local opposition. The issue has been contentious in parts of the East Coast and in the Southwest, where two high priority transmission corridors for power lines were proposed. Rep. Frank Wolf, R-Va., warned colleagues that unwanted power lines could come to their district.

MELISSA, Texas - An orange flag marks where Gary Lisle planned to put up a 33-foot windmill behind his house. But that's about as far as his green idea got in this Dallas suburb. Denied a building permit in March, Lisle joined the growing ranks of frustrated homeowners across the U.S. whose hopes of harvesting wind energy in their backyards have been dashed. Some communities have outlawed residential turbines. Others entangle applicants in so much red tape that they simply give up.

A scientific panel has concluded that new wind farms could generate up to 7 percent of U.S. electricity in 15 years. That's the positive side. The negative side is not good news for our fine feathered friends.

Ducks in the Dakotas, tanagers in Texas and grosbeaks along the Gulf of Mexico could all be hit by the rapid growth of wind power unless the renewable electricity farms are carefully sited, experts said. "The first three rules of avoiding impacts with wind turbines are always going to be location, location, location," Mike Daulton, a spokesman with the National Audubon Society, said in a telephone interview. Clean-energy wind farms are cropping up rapidly in the United States on rising concerns about greenhouse gas carbon dioxide emissions and flat output of natural gas, which fires most of the power plants built since the 1990s. U.S. wind power is expected to increase by 26 percent in installed generation this year, after similar growth last year. A study by the National Academy of Sciences released late this week found that wind energy could reduce the energy sector's carbon dioxide emissions by 4.5 percent by 2020. But federal and state governments should take environmental impacts of wind energy more seriously as part of the planning, locating and regulating turbines, it said.

A continued rapid pace of wind power development in Texas has firmed up its claim to the title as the state with the most wind power capacity.

In a precedent-setting move that could have national implications, the California Independent System Operator Corporation (California ISO) filed today with its regulator, the Federal Energy Regulatory Commission (FERC), to approve in concept a financing plan for transmission trunklines to remote locations in order to get green power from multiple users onto the grid. If the new payment mechanism is approved and implemented, it would be a first-of-its-kind means of removing financial barriers that can hinder development of wind, solar, geothermal and other renewable energy resources. Fostering these resources can help California achieve its Renewable Portfolio Standard (RPS), which requires most utilities in the state to obtain 20 percent of the electricity they deliver from environmentally-friendly resources by 2010. Unlike natural gas-fired power plants that can usually be built relatively close to existing high-voltage facilities, renewable generation is often built in remote areas. “Wind turbines, large solar power plants and geothermal resources all need to be built close to their natural fuel sources,” said California ISO President and CEO Yakout Mansour. “The California ISO is committed to removing barriers to these types of green resources and doing everything we can to help meet the State’s renewable standards and climate change policies in a timely and reliable manner.”
