Bird and bat deaths from wind farms have been among the few environmental negatives of this growing source of alternative energy. But a new study offers hope that a solution can be found.
A new study of the interaction between bats and wind turbines at the Casselman Wind Power Project found that turning off the turbines during low wind periods reduced bat mortality by more than 70 percent.
Iberdrola Renewables, owner of the Casselman wind farm in southwestern Pennsylvania, partnered with independent conservation group Bat Conservation International (BCI) to collect the data. From late July to mid-October 2008, Iberdrola Renewables and BCI researchers conducted a controlled experiment in which selected wind turbines at the Casselman project were stopped during relatively low wind-speed nights in the late summer and early fall.
