More than 600,000 bats were killed by wind energy turbines in 2012, a serious blow to creatures who pollinate crops and help control flying insects, according to a new study from the University of Colorado Denver.
“The development and expansion of wind energy facilities is a key threat to bat populations in North America,” said study author Mark Hayes, PhD, research associate in integrated biology at CU Denver. “Dead bats are being found underneath wind turbines across North America. The estimate of bat fatalities is probably conservative.”
The study, which analyzed data on the number of dead bats found at wind turbine sites, will be published next week in the journal BioScience.
