The Danger to Bats

“Wind turbine deaths could severely affect bat populations”

While some bats are killed by direct contact with industrial wind turbine blades, about 90% of dead bats found under turbines have internal hemorrhaging, according to a 2008 University of Calgary. The research showed the injuries were consistent with changes in air pressure close to the wind turbines. When the bats experienced this radical change of air pressure, their lungs exploded and the bats died.

The researchers said wind turbine deaths could severely affect bat populations.Because their rate of reproduction is low, bat populations could find it difficult to recover from the deaths caused by industrial wind turbines.

There is no way to lower the pressure around the rotating turbine blades without limiting the effectiveness of the turbines.
