Iron pyrite was among the risks to water quality that opponents of the Sandy Ridge Wind Farm pointed to during Monday's state Department of Environmental Protection public hearing. "Given the formations, there is a likelihood there's some up there," Michael J. Byle, a civil engineer who is working with Gamesa USA, said after the public meeting and hearing on the proposed wind farm. Core drilling has just begun, and the company is looking for the acid rock.

Anti-windfarm campaigners say that installing turbines at Todd Hill could have a devastating impact on wildlife and tourism. Members of the Put People First (PPF) group have highlighted concerns for birds, bats and other animals if a Novera Energy application for four turbines near Pigdon is approved. They say the area is host to a wide range of species.

Proposals to build Europe's largest onshore windfarm in the Shetland Islands at a cost of £800 million could be scaled back, according to developer Viking Energy, writes Will Nichols. The limited company originally presented plans for the 150 turbine, 540MW project to the Shetland Islands council this summer. However, last week, a spokesman for Viking Energy told NewEnergyFocus.com that the company is to submit an addendum to its plans early in the new year in a response to concerns flagged up during consultation, including over bird life and landscape.

A remote corner of East County is shaping up as a battleground between companies pushing wind farms as clean and cheap power generators and activists who view them as a blight on the landscape. It has put environmentalists in the position of opposing renewable energy because, they say, it's in the wrong place. Drawing the most attention is a plan by the Spanish conglomerate Iberdrola to build about 100 skyscraper-sized towers in and near the McCain Valley, a federal conservation area abutting Anza-Borrego Desert State Park.

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.

Opponents to a proposed electricity-generating turbine project in Champaign County questioned Thursday during state hearings whether the wind-turbines would harm an endangered species of bat, but a researcher who studied the issue said the windmills would not. ...UNU attorneys argued the study did not follow specific guidelines for net placement developed by the department of fish and wildlife. A follow-up study by wildlife officials, however, did find evidence of the Indiana bat in the area. Meinke said she had worked closely with officials from the department of fish and wildlife when she conducted the study, which was deemed adequate at the time.

Wisconsin’s endangered species law (s. 29.604, Wis. Stats.) requires the Department of Natural Resources to notify the public when it proposes to authorize the incidental taking of a state endangered or threatened species.

A proposal to build the first wind farm in Western Washington may stall, and may even be doomed, because of concern that turbine blades would kill members of an endangered bird species, a state lawmaker says. "I'm just not feeling real confident that this is going to grab hold and move forward very fast," Rep. Dean Takko, D-Longview, said last week. "There are key players who aren't very supportive, and I think it's going to hold this up. Is it going to kill it? I don't know."

Bill Evans wants to make it clear he's not against wind turbines. "I'm not anti-wind. I'm a consultant who people call from both sides when there's a concern about the impact on migrating birds," he said. Evans, 50, is an Ithaca-based ornithologist who has studied bird migration in North America for more than 25 years. He helped start the Cornell Laboratory of Ornithology's research into avian night flight calls in the mid-1990s and in 1998 founded the non-profit group Old Bird Inc.

Local governments are beginning to flex their permitting authority to challenge commercial-scale wind farms, a trend some industry observers say could impede broader federal efforts to expand renewable energy production. The latest round in the emerging battle between local governments and wind-energy developers occurred last week in Kansas, where the state Supreme Court upheld a Wabaunsee County zoning ordinance banning industrial-scale wind ...Experts say the Wabaunsee ordinance, unanimously upheld by the Kansas court, is a key test of local governments' power to effectively ban large-scale wind farms, as opposed to blocking a specific project or proposal.

Proponents of small wind systems got a lift this week when the county attorney said a proposed bill designed to streamline the permitting process would not open the county to legal or financial liability should an applicant's windmill kill an endangered seabird. The announcement, delivered by Deputy County Attorney Ian Jung, who specializes in planning issues and advises the Kaua‘i Planning Commission. ...While Jung's statement could go a long way to resolving one issue standing in the way of the bill's passage, there are several other factors that have yet to be addressed.

The US Forest Service is one step closer to issuing a decision on the Deerfield Wind Project. The Manchester Ranger District of the Green Mountain National Forest has reviewed the Public Service Board's approval and the public comments it received regarding last year's Draft Environmental Impact Statement. Now the forest service is ready to release a supplemental report on their latest findings. But despite the new information, some state officials are urging the forest service take extra precautions before they make a final decision.

The dirty little secret about the windmill farm at Altamont Pass is that it slaughters thousands of birds every year while politicians turn a blind eye. Four years ago, environmental groups filed suit after the Alameda County Board of Supervisors effectively allowed the farm's several owners to keep killing birds despite evidence that the deaths could be greatly lessened.

The thousand of birds killed by the wind turbines at Altamont Pass tainted the reputation of the renewable energy source. But according to a recent report by the Ventana Wildlife Society and the Stanford Solar and Wind Energy Project, smaller wind-power projects may be able to harvest energy in some parts of Monterey County without harming the endangered California condor. "The condor is the main thing that's been holding up the development of wind-power projects in Monterey County," said John Roitz.

Attorneys for the developers of a West Virginia wind farm questioned all but their last witness in a trial over whether the project will harm an endangered bat. The defense witnesses said Friday in U.S. District Court in Greenbelt that netting has not captured any Indiana bats and disputed audio recordings that witnesses for the plaintiffs say show the endangered bats are at the site.

The 39-turbine Roaring Brook wind farm project in the town of Martinsburg received little public comment Wednesday. And the four people who did speak at the town Planning Board public hearing on the project expressed mixed opinions. "There is insufficient evidence to suggest that birds won't be displaced by Roaring Brook Wind Farm," said Chris K. Lajewski, the Northern New York land steward for the Nature Conservancy.

Workers atop mountain ridges are putting together 389-foot windmills with massive blades that will turn Appalachian breezes into energy. Retiree David Cowan is fighting to stop them. Because of the bats. ...It is the first court challenge to wind power under the Endangered Species Act, lawyers on both sides say. With President Obama's goal of doubling renewable energy production by 2012, wind and solar farms are rapidly expanding. As they do, battles are being waged to reach the right balance between the benefits of clean energy and the impact on birds, bats and even the water supply.

A proposed West Virginia wind power project will harm a tiny, endangered bat and its developers should be should be required to obtain permits under the Endangered Species Act, attorneys for two environmental groups argued Wednesday in federal court. The developers admit bats will be killed by the turbines, but refuse to acknowledge the endangered Indiana bat will be among them, plaintiffs attorney Eric Glitzenstein argued in his opening statements.

The 124-turbine wind farm being built by Rockville-based Beech Ridge Energy would put the lives of endangered Indiana bats, and other bat species, in danger, according to the plaintiffs -- The Animal Welfare Institute, Mountain Communities for Responsible Energy and David G. Cowan. Plaintiff's witness Michael Gannon, a bat biologist and professor at Pennsylvania State University, said he is "very much in favor" of wind energy, but remains concerned that this project could have a devastating effect on the Indiana bat.
