Wind turbines have fix for danger to flying animals


Plans to increase renewable power production around the world from wind turbines have met serious environmental challenges from dangers posed to birds, and especially bats.

The airborne mammals die when drawn into areas of low pressure near the turbines, resulting in massive internal hemorrhage. Bats are very important ecologically around the world.

Engineers are finding that they can turn off the turbines during periods of low wind speed, when bats are less likely to be around.

The Washington Times story by Tait Militana is “Wind energy finds fix for exploding bats”, Monday March 23, 2009, link here.

The problem recalls a similar one for the airline industry: birds flying into jet engines.
