Wind farms' impact remains unclear
WASHINGTON (AP) -- Wind farms could generate as much as 7 percent of U.S. electricity in 15 years, but scientists want to spend more time studying the threat those spinning blades pose to birds and bats.How do birders concerned about climate change balance the wind farms' potential reduction in the use of fossil fuels against the potential impact on birds and bats?
The towers appear most dangerous to night-migrating songbirds, bats and some hunting birds such as hawks and eagles. The risk is not well enough known to draw conclusions, a panel of the National Research Council said Thursday in a study requested by Congress.
