As the debate goes on, the turbines are going up in record numbers -- a trend that's expected to continue as the clean energy industry moves to take advantage of concerns about global warming and rising fossil fuel costs. ...Rick Webb, a senior scientist in the University of Virginia's Department of Environmental Sciences, isn't so sure wind power, particularly on the mountains of the mid-Atlantic, will help much. Webb participated in a National Academy of Sciences committee that studied wind power and released a report this year that found wind power is growing, but in many places, guidelines for development are lacking. ''I think the potential electrical supply and the potential reduction to other sources of power won't be great enough to compensate for environmental damages on the ridges,'' Webb said, adding he believes offshore development of wind farms would be more useful because there is a more-abundant supply of wind there.

Opposing perspectives rose from residents who gathered Monday to probe the proposed alternative energy development site along Big Sewickley Creek Road in Bell Acres. Many borough residents questioned the potential noise level and electromagnetic presence of the site, which would include a 66-foot wind turbine. Others questioned the potential threat to great blue herons that nest along Big Sewickley Creek. Some questioned the visual impact on the borough's landscape.

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.

A company that plans to build a wind turbine facility in the southern part of Wyoming County says that it wants to be a good corporate citizen. While BP Alternative Energy sponsored two outdoor events this summer, some people are unhappy with the company, including Richard Ide, whose cabin in Mehoopany is near a stretch of land where transmission lines may be placed. "They (BP) have the resources to drive me into the ground, which is what they are trying to do," Ide, of Tunkhannock, said. "I have hired two attorneys."

A Blair County judge has upheld all but two civil charges brought against two wind companies by a Juniata Township couple, who have complained that 40 wind turbines on Blue Knob Mountain are noisy and cause light to flicker in their home. ...Milliron refused to strike a charge of fraudulent misrepresentation against Gamesa and a similar charge, plus others, against Allegheny Ridge.

The Altoona City Authority is asking Logan Township to enlarge its wind turbine zone by 775 acres, more than double the acreage expansion request the township turned down in May. Authority General Manager Mark Perry presented supervisors last week with aerial maps showing the township's wind zone and the authority's land. Perry asked for an expansion beyond the zone's Route 36 northern border to include a portion of the authority's land. Supervisors made no immediate decision, but Chairman Frank Meloy asked if arrangements could be made to visit the site...

Two Fayette County commissioners voted to sign an agreement Thursday that addresses neighbors concerns regarding the location of wind turbines in a $100 million project proposed for Wharton, Georges and Springhill townships. Commissioners Vincent Zapotosky and Vincent A. Vicites voted to sign the agreement between PPM Atlantic Renewable Energy Corp./Iberdrola Renewables, the county and property owners that petitioned the court to be included in the case. Commissioner Angela M. Zimmerlink voted against the action, saying she doesn't believe the commissioners have the authority to approve changes to the proposed project.

A Lycoming Court judge has rejected three court appeals filed in an attempt to stop a proposed wind farm in northern Lycoming County.

A local doctor and his wife have filed a lawsuit against the operator of a nearby wind farm saying they are losing sleep from the the constant ''whooshing'' and ''screeching'' caused by the wind turbines. Blair County Judge Daniel J. Milliron on Friday concluded his initial review of the lawsuit brought by Todd and Jill Stull of Portage RD, Blair County. Milliron kept the lawsuit largely intact although he dismissed several counts of the legal complaint including one that charged Gamesa Energy and its subsidiary, Allegheny Ridge Wind Farm LLC, with creating a public nuisance.

The Juniata Township couple seeking relief from noisy wind turbines has taken their complaint to Blair County Court. Todd and Jill Stull, in a lawsuit filed at the courthouse, accuse Gamesa Energy USA LLC and the Allegheny Ridge Wind Farm LLC of destroying their quality of life and damaging their health. They're seeking an injunction ordering the noise to be reduced. ...The lawsuit also accuses Gamesa and the wind farm of securing permits and approvals to build on the basis that the turbines would cause no noise.

A Blue Knob couple is seeking unspecified monetary compensation and is asking a court to intervene to reduce noise and vibration from energy generating turbines in the Allegheny Ridge Wind Farm. A Pittsburgh attorney representing Todd and Jill Stull of Pine Springs Lane, Portage, filed a 14-page civil lawsuit in Blair County court naming Gamesa Energy USA, developers of the wind farm in Portage Township, Cambria County, and Juniata and Greenfield townships, Blair County. ...At the urging of residents, the Portage Township supervisors say they will hire a sound expert to determine whether the turbines are being operated in violation of the ordinance. Similar action already has been taken by Juniata Township officials.

Blair County Judge Daniel Milliron on Friday dismissed the counts against Gamesa, which made and installed the turbines, but left intact the lawsuit against Allegheny Ridge because he believes the complaints deal with operational problems. Allegheny Ridge operates the wind farm.

The Tioga Preservation Group's land use appeal of the Tioga County Planning Commission's decision to grant conditional approval for a wind farm project has been denied, opening the door for the construction of 124 wind turbines in Tioga and Bradford counties. On Aug. 8, Tioga County Court of Common Pleas President Judge Robert E. Dalton Jr. issued an order denying the appeal of the group, and upheld the planning commission's preliminary conditional approval of the land-use application made by AES Armenia Mountain Wind LLC, according to court documents.

One week after moving in, Loudenslager found out that a swath of the farm where cows graze and alfalfa grows soon could be cleared to make way for a high-voltage power line. "It's like a punch to the gut," Loudenslager said. "This is where I've wanted to be my whole life." Loudenslager's farm north of Boonsboro sits on one of several routes that have been suggested for the Potomac Appalachian Transmission Highline (PATH), which would run from St. Albans, W.Va., through Bedington, W.Va., to Kemptown, Md., in Frederick County.

The company that pursued building wind turbines in Logan Township has a new plan with taller versions that are confined to the township's wind zone. Representatives for Gamesa Energy recently submitted revised plans for a wind farm of 19 turbines in the Chestnut Flats area zoned for that type of land use. The company previously proposed building 25 wind turbines, with 17 inside the zone and eight outside.

An open house Wednesday by Spanish energy producer Gamesa USA is not exactly the kind of forum Tyrone's mayor had in mind when he asked the company to hold a public meeting on its proposed Ice Mountain wind farm. ... As it is set up now, with Gamesa representatives talking to people one-on-one, there's a missed opportunity for more people to hear how the company is addressing its critics.

On Capitol Hill, the Audubon Society is leading the fight to increase production of climate-friendly power. So why are Audubon enthusiasts battling a wind farm that could help meet that goal? For one thing, there are trout in nearby streams, which activists say are at risk from chemical and sediment runoff from construction of 30 turbines, each soaring about 400 feet -- taller than the Statue of Liberty. Then there are the bats and hawks, which might be puréed by the giant blades that would catch the wind gusting along the Allegheny Mountains of Western Pennsylvania. "They're enormous," says Tom Dick, a retired veterinarian who founded the local Audubon chapter. "When you start looking at this, it's like, 'hell, this is not right.'"

Eric Glitzenstein, a Washington, D.C., attorney who is preparing the lawsuit, referred to the Endangered Species Act. "The courts view the unauthorized loss of even a single member of such a species to be an irreparable harm that should be prevented," he wrote in an e-mail. The letter of intent is required by the Endangered Species Act, he said. The groups have yet to decide where the suit would be filed, Glitzenstein added. "Our hope is that Gamesa - which touts itself as an environmentally responsible company - will agree either to do the right thing and abandon this ill-considered project site or, at least, do what is required by federal law and not proceed without applying for an ‘incidental take permit' from the U.S. Fish and Wildlife Service." The Indiana bat has been a protected species since 1967.

Pennsylvania's mountain ridges are on track to teem with industrial wind turbines -- enough that, if placed on the 359-mile Pennsylvania Turnpike, they would stretch seven per mile. The turbines will require clearing a combined 10,000 acres of mountaintops. Each turbine would reach heights that rival Pittsburgh's skyscrapers. They could make their owners more than $300 million in federal subsidies and power more than 1 million homes. But they wouldn't remove a single coal-fired power plant from service.

Borough officials have restricted hunting in a 50- to 60-acre radius around a Gamesa Energy USA wind-monitoring tower on borough-owned land at Adams Run Reservoir on Second Mountain in Pine Grove Township. The Philadelphia-based company is working to build wind turbines on Second and Sharp mountains in the township and is completing an environmental study at the Adams Run Reservoir tower.
