Wind turbines a breeze for migrating birds (http://www.newscientist.com/channel/earth/mg18625045.500)

MIGRATING birds seldom dice with death among the spinning blades of wind turbines. Instead, they give them a wide berth, according to a study of a Danish offshore wind farm.

I see the word seldom.  The question is "how many".  Also becsuse the study is by the wind farm, my confidence to the report has dropped.

The HK Electric has announced building 3 wind turbine generators in Lamma.  We have a chance to see it ourselves.

Yes,  we should see evidence from both sides.

ALAMEDA COUNTY Wind farms to spare the birds 2,500 turbines in Altamont Pass to stop for winter migration

Jim Herron Zamora,
San Fransciso Chronicle Staff Writer

Friday, September 23, 2005

Half of the 5,000 windmills in the Altamont Pass will be closed for three months this winter to protect migratory birds under a plan that Alameda County supervisors adopted Thursday, over protests from environmentalists who said all the turbines should be closed for the season.

The move marked the first time during a 24-year dispute at the world's largest wind farm that the county board and windmill owners have agreed to shut down some of the wind turbines to protect birds. The board had approved an earlier version of the plan in July.

On Thursday, supervisors voted 4-1, with Supervisor Gail Steele opposed, to renew the operating permits for the wind farms, but only under new restrictions designed to reduce the number of birds that turbines kill each year, which is about 4,700.

The new plan is a compromise that will close half the turbines every year during the winter migratory season, when more birds are traveling through the Altamont Pass. The winter months are also when the least wind is generated, operators said.

"These are creative and meaningful conditions," said Supervisor Scott Haggerty, whose southeast county district includes the Altamont Pass. "These new conditions go further than anyone would have thought. This is fair place to start coming up with a balance."

Under the plan, half the turbines will not be spinning from Nov. 1 through the end of February. About 2,500 windmills will be shut down in November and December, then turned back on while the other 2,500 will be closed down in January and February. Between 100 and 200 older turbines that are considered the worst offenders will be turned off permanently.

The county and the wind power companies also agreed to conduct a series of studies to see which turbines kill the most birds and see how they can reduce deaths.

The Altamont wind turbines, first erected in the 1970s, provide enough energy to power about 120,000 homes. But the turbines also sit along the Pacific Flyway -- the main route for the winter migration of birds.

More birds are killed at Altamont Pass than any other wind-power area in the nation. These include about 500 raptors such as golden eagles, red-tailed hawks and burrowing owls, according to studies by the California Energy Commission. The hills and mountains near the pass are one of the world's largest nesting grounds for golden eagles, a federally protected species.

Wind turbine operators said they are willing to live with the new restrictions even though it will cut their revenue by 10 percent, said Rick Koebbe, president of Altamont Winds Inc., one of the larger producers.

"This will affect our business, but we are happy to work to reduce bird deaths," Koebbe said.

But environmentalists and state Attorney General Bill Lockyer wanted the board to go further and shut down all the wind turbines from November to February until they can be replaced by newer models that are less likely to kill bald eagles and other birds.

"After 20 years of doing nothing, we needed the board to hit a home run. Instead, they hit a bloop single," said Jeff Miller of the Center for Biological Diversity. "It's great that the board is finally doing something. But the question is: Is this enough? We don't think it is."

Miller's group is one of several environmental organizations that have a lawsuit against the wind farm operators that is pending in Alameda County Superior Court. Lockyer agreed to review the underlying legal issues at the request of Judge Ronald Sabraw, who is presiding over the lawsuit.

In July, Lockyer's office wrote a letter urging the board to go further and adopt many recommendations to reduce bird deaths proposed by the Center for Biological Diversity and the Audubon Society. No representative from his office attended Thursday's board meeting, and no one was available for comment afterward.

Environmentalists said they may sue the county over the new regulations, which they said are in violation of state laws governing planning and wildlife.

"Altamont Pass never would have been built if we had known how critical that site is," said Elizabeth Murdock, executive director of the Golden Gate Audubon Society. "That project never would have gotten through the approval process."
