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.

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.

US Fish and Wildlife Service, Wet Virginia field office, issued these comments regarding the Pinnacle wind power project proposed for ridgelines in Mineral County, WV. The comments pertain to the Habitat Characterization and Assessment of Rare, Threatened, and Endangered Species for the Pinnacle Wind Farm (BHE Environmental 2009a); the Avian Risk Assessment for the Pinnacle Wind Power Project (Kerlinger 2009); and the Bat Risk Assessment: Pinnacle Wind Farm (BHE Environmental 2009b). Excerpts of the letter are provided below. The full report can be accessed by clicking on the link at the bottom of the page.

It's clear that global warming threatens ecosystems and that we need to take action to reduce carbon emissions if we hope to maintain the planet's biodiversity. But one potential solution carries threats of its own that need to be mitigated. ...Although wind development is far less destructive than many types of energy production, such as mountaintop-removal coal mining, wind power's threats to wildlife are not inconsequential. Regions with sustained high winds frequently overlap prime bird habitat, including the sagebrush and grasslands that sustain declining populations of sage grouse and prairie chickens. In addition to habitat issues, bird collisions with wind turbines are mounting.

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 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.

Bird experts have welcomed the Scottish Government's decision to refuse permission for a wind farm they said would have posed a risk to golden eagles. WPR Wind Ltd hoped to build a 14-turbine wind farm near Inveraray in Argyll. However, RSPB Scotland objected to the proposal on the grounds that the site was one of the most productive areas in the country for golden eagles.

Lane Johnson said the great blue herons that perch on and near his property in Bell Acres are like an annoying little brother that you wish would go away, but you also feel obligated to protect. ...he spoke during a public hearing Monday night against the proposed erection of a 60-foot wind turbine that would go up about a half-mile away from the herons' nesting spot -- or rookery -- because it might endanger the birds.

Two of California's highest priority environmental causes, promoting renewable energy and saving the California condor, are on a collision course. The proliferation of prop wind turbines and their well documented history of killing birds of prey have put the future of California condor at great risk. The fact is, in recent years many missing Condors have most likely perished at wind farms in California. Many of the captive bed condors, released into the wild since 1992 have turned up missing. Nearly 1/3 of all the captive bred condors released, perish for unknown reasons. If one looks into the scientific literature, collision is nearly always listed as a major cause of death to Condors.

So why are wind companies not being prosecuted for killing birds? Rob Lee, now retired, was one of the Fish and Wildlife Service's lead law-enforcement investigators on the problem of bird kills in Western oil fields. Lee said that he doesn't expect to see any prosecutions because the wind industry is politically correct. This suggests a double standard. In protecting America's wildlife, federal law-enforcement officials are turning their backs on the harm done by "green" energy.

Wind farms can reduce bird numbers by up to half, according to a new study by the Royal Society for the Protection of Birds, that raises questions about the charity's support of the new technology. ...It suggested that the most likely cause of the decline is the fact that birds are less likely to live near wind farms because of the noise and development.

The RSPB Scotland study looked at 12 operating upland wind farms in the UK and found that numbers of several birds of high conservation concern are reduced close to the turbines. Affected birds include the hen harrier and golden plover, which are protected under European law, and the curlew, which is a high-priority species under the UK Biodiversity Action Plan.

The slaughter at Altamont Pass is being raised by avian scientists who say the drive among environmentalists to rapidly boost U.S. wind farm power 20 times could lead to massive bird losses and even extinctions. New wind projects "have the potential of killing a lot of migratory birds," said Michael Fry, director of conservation advocacy at the American Bird Conservancy in Washington. ...Officials in the wind energy industry say migratory birds and birds of prey, including eagles, are killed each year at some of the nation's biggest wind farms, but they say the concerns are overstated.

Scotland's ospreys are once again starting their epic annual winter migration to West Africa. Forestry Commission Scotland (FCS), the biggest land manager in the country, has been keeping a close watch on the success of the fish-eating birds of prey. One of the birds monitored using satellite tracking technology is known as Red 8T.

A new study indicates that winds turbines could be contributing to the local extinction of an endangered vulture in southern Spain. ...The results suggest that if the number of wind turbines stays the same as it is today, the population will go extinct 10 years sooner than if there were no wind farms.

Over the past two decades, federal officials have brought hundreds of similar cases against energy companies. In July, for example, the Oregon-based electric utility PacifiCorp paid $1.4 million in fines and restitution for killing 232 eagles in Wyoming over the past two years. The birds were electrocuted by poorly-designed power lines. Yet there is one group of energy producers that are not being prosecuted for killing birds: wind-power companies. And wind-powered turbines are killing a vast number of birds every year.
