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.

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.

The federal lawsuit filed against Beech Ridge Energy and its parent corporation by Mountain Communities for Responsible Energy and others will culminate with an evidentiary trial starting October 21st in Greenbelt, Maryland. ...Beech Ridge Energy concedes that approximately 135,000 bats could be killed during the twenty-year operation of the project. Despite this staggering figure, Beech Ridge Energy's staff have testified previously that Indiana bats were not likely to be killed by the project because pre-construction surveys did not establish presence of the species on the project site. However, the discovery process leading up to this October trial has exposed evidence to the contrary.

Reporting in The Journal of Wildlife Management, researchers write about a strategy for protecting migratory bats from fatal encounters with wind farms. Study author Robert Barclay discusses the method, which halves bat fatalities without significantly reducing energy production - or profits.

Turbines already are taking a heavy toll in West Virginia and Pennsylvania. The Pennsylvania Game Commission released a report last spring showing the death rate is highest for bats, which additionally face being wiped out by a mysterious phenomenon called "white-nose syndrome." The evidence has mounted since studies in 2004 showed 1,500 to 4,000 bats annually were killed by the 44 turbines on West Virginia's Backbone Mountain.

Wind energy has been touted as cost-effective to produce clean energy as well as jobs. That promise, along with new government subsidies, has helped wind turbines pop up on hills and fields throughout America. But not every environmentalist is happy about that development. Critics charge that wind-energy development can cause habitat fragmentation-a displacement of a species that can eventually reduce its numbers-as well as the deaths of birds and bats (a species that is especially vulnerable due to its low reproductive rates) that collide with the wind turbines' massive rotor blades.

Massive wind turbines seem to be killing more and more migratory bats, prompting research into these neglected creatures and efforts to minimize the toll. ...The deaths have led to a flurry of research on migratory bats and their behavior. "The problem with bats and wind energy has pushed a lot of work that wouldn't have occurred otherwise," says Edward Arnett of the Austin, Texas-based nonprofit Bat Conservation International. Indeed, at a January conference in Berlin on migratory bats, wind farms were a dominant theme. Scientists are racing to figure out what brings the bats in contact with wind turbines, and what can be done to save them.

Wildlife biologists from a Maine environmental firm will share two year's worth of research on Vermont's bat populace to help shed light on "white-nose syndrome," the disease that has killed at least 400,000 bats in the Northeast. Stantec of Topsham, Maine, has installed five of its acoustic bat detectors on Grandpa's Knob in Castleton. The devices detect and log bats that pass by each unit, according to company spokeswoman Alison Smith.

Although the zoning board now has ruled to approve a portion of the proposed wind turbines, recent action by the board of county commissioners would allow a wind power project to start without going before the zoning board. Earlier this month, Commissioners Vincent Zapotosky and Vincent A. Vicites voted to change the zoning ordinance to allow wind turbines as a permitted use in A-1, M-1 light industrial and M-2 heavy industrial zones. Previously, wind turbines were only permitted after obtaining a special exception from the zoning board.

Wind turbines in Oklahoma may be good for producing clean energy, but they are bad news for bats and the lesser prairie chicken. As government officials try to harness the Oklahoma wind as a practical power source, they must also be mindful of the birds and bats most affected by wind farms.Western Oklahoma is home to bat colonies and the lesser prairie chicken, but the area also has some of the best real estate for wind farms.

A proposed wind farm on a forested ridge in eastern Skamania County could harm bats, raptors and other wildlife, a state wildlife biologist says. ... Ritter, a wind mitigation biologist based in Pasco, said the survey data on bats was "extremely interesting and alarming."
