... a coalition of local utilities is grappling with one of the thorniest challenges in the field of renewable power: how to store the excess energy windmills create when demand is low so it can be used later, when the need is greater. The group is building a system that will steer surplus electricity generated by a nearby wind farm to a big air compressor. Connected to a deep well, the compressor pumps air into layers of sandstone. Some 3,000 feet down and sealed from above by dense shale, the porous sandstone acts like a giant balloon. Later, when demand for power rises, this flow is reversed.

U.S. Rep. Randy Neugebauer, representing Young County and part of Archer County, is seeking the feasibility study as wind energy development moves forward in Texas. "The basic point behind this is let's look at it from every single angle to make sure that we're doing this right and there aren't any mistakes," Neugebauer spokesman Michael Frohlich said.

WASHINGTON, DC, United States (UPI) -- Multiple reports and studies, especially those published in the last year, suggest the United States, specifically the East Coast, has great potential for offshore wind. The politicized debate over whether to develop wind power offshore has dragged on since the late 1990s, when the first project was proposed in Cape Cod, Mass., off the Nantucket Sound. Since then there have been several other proposals, none of which has been completely approved.

The Energy Department announced Monday it will provide $4 million to two projects in Texas and Massachusetts for research into designing and building the next generation of large wind turbine blades.

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.

Meanwhile, as the nation considers options for future energy development, environmental questions have emerged as important considerations, the NRC report states. Proponents point out that wind-energy facilities emit no atmospheric pollutants and are driven by a renewable source, addressing multiple environmental concerns such as air quality and climate change. However, the NRC report also points out that the expansion of such facilities can carry adverse environmental impacts.

Wind turbines produce none of the pollution that contributes to climate change, a top priority among many environmentalists. But wind turbine projects in Texas have run into opposition from birding groups, who say the giant windmills kill birds, and from some ranchers, who worry that they could hamper hunting and tourism activities. Although the report found "no evidence of significant impacts on bird populations," it suggests that policymakers consider aesthetic, cultural, human health and environmental impacts before approving wind power projects.

WASHINGTON - An unusual coalition of conservationists and coal advocates told Congress on Tuesday that before the nation continues its rapid expansion of wind power, an assessment is needed of how many bats and birds are maimed and killed by wind turbines' blades. That study should be followed up with regulations to protect those species, witnesses told a House Natural Resources subcommittee.

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.

According to Friday's Nuclear Market Review (NMR), many market participants were left stunned by the recent record jump in the weekly spot uranium price. The market has increasingly diverged between those who have U3O8 and those without. Utilities with existing supply contracts "are heaving a sigh of relief," NMR editor Treva Klingbiel wrote. And those trying to find uranium in today's climate "are forced to face the reality of a seller's market," she said.

Some call it a carbon-free alternative to fossil fuels, but others point to significant environmental costs. In Kansas, where winds blow strong, the push for clean energy includes not only new wind turbines but also new nuclear-power plants as part of a "carbon-free" solution to climate change. It's an idea that may be catching on. At least 11 new nuclear plants are in the design stage in nine states, including Virginia, Texas, and Florida, according to the Nuclear Energy Institute website. But that carbon-free pitch has researchers asking anew: How carbon-free is nuclear power? And how cost-effective is it in the fight to slow global warming? "Saying nuclear is carbon-free is not true," says Uwe Fritsche, a researcher at the Öko Institut in Darmstadt, Germany, who has conducted a life-cycle analysis of the plants. "It's less carbon-intensive than fossil fuel. But if you are honest, scientifically speaking, the truth is: There is no carbon-free energy. There's no free lunch."

TXU, if its buyout agreement is approved, will double the amount of money it spends on wind power purchases. The deal between the Texas utility giant and a group of investors led by Kohlberg, Kravis, Roberts & Co. is the largest private investment merger in U.S. business history at $45 billion. The buyout comes to $32 after TXU’s $13 billion in debt is paid off. Included in the group of investors are Texas Pacific Group, Goldman Sachs & Co., GS Capital Partners, Lehman Brothers and Morgan Stanley. Goldman Sachs, Lehman Brothers and Morgan Stanley are already investors in the wind market. Under the agreement, shareholders would receive $69.25 per share, 25 percent more than the closing price Friday when the deal was being finalized.

Texas is in a nationwide race for a giant new U.S. Department of Energy-backed wind turbine research and development center.

Greenblatt noted that while wind power could produce impressive amounts of peak energy during strong gusts, the biggest problem was wind power’s intermittency. The problem could be addressed by a process called compressed air energy storage, where excess energy could be used to pump compressed air into underground storage facilities that could include abandoned mines. When the wind was not blowing, he said, the compressed air could be tapped and combined with the burning of natural gas to create high-efficiency electrical generators approximating the efficiency levels of coal-fueled power plants.

The Texas project, announced in June with plants scheduled to begin operations in 2014, is expected to be the first in a new wave of economical and emissions-free nuclear power plants.

In June, Austin-based Green Mountain Energy Company – self-described as "one of the nation's largest retail providers of cleaner electricity products," generated from sources such as wind, solar, water, biomass, and natural gas – announced the crosstown relocation of its headquarters from aquifer-sensitive west Austin to an award-winning green office tower downtown, in anticipation of growth and expansion. By the time the move was complete, however, the energy provider had discontinued servicing about 480,000 customers in Ohio and Pennsylvania, laid off 15% of its workforce, and found itself facing suit in federal court. Green Mountain blames regulatory and market obstacles for its woes, but its critics cite an over-reliance on natural gas and a lack of investment in the very clean energy sources the company has made its trademark.
