More than a half-million bats were killed by flying into high-speed wind energy turbines last year, according to new research scheduled for publication next week in the journal BioScience.Previous estimates had said that the clean-energy producing mechanisms were responsible from between 33,000 to 880,000, but a new analysis of dead bats found at wind turbine sites conducted by University of Colorado-Denver researchers places that figure at over 600,000.In a statement, the university calls the discovery “a serious blow to creatures who pollinate crops and help control flying insects,” while study author Dr. Mark Hayes, a research associate in
