Dead Bats and the Downside of Wind Power
By Jerry A. Kane
Pennsylvania’s 420 wind turbines have killed more than 10,000 bats last year alone, and the Ruler’s push to solve America’s energy woes with green technologies by 2030 will add another 2,480 killing machines to afflict the creatures and blight the state’s landscape.
“Dead bats are turning up beneath wind turbines all over the world. Bat fatalities have now been documented at nearly every wind facility in North America … and several of these sites are estimated to cause the deaths of thousands of bats per year.”
Bats are nature’s pest controllers. They eat millions of crop destroying insects every year, which saved Pennsylvania farmers about $74 an acre last year or about $278 million. Fewer bats mean more insects, and that leads to more pesticides and higher food prices.
“A colony of just 100 little brown bats may consume a quarter of a million mosquitoes and other small insects in a night. That benefits neighbors and reduces the insect problem with crops.”—Miguel Saviroff, Penn State Cooperative Extension agricultural financial manager
Bats are not the only causalities of wind turbines; 1,680 birds were also killed last year. Both bats and birds die from flying into the turbines’ blades; however, most bats die when their lungs explode from the rapid drop in air pressure around the turning blades.
Wind companies are developing high-pitched sound technology generators to keep the bats from coming too close to the turbines. But then there’s the adverse effect of high-pitched noises on the environment.
Oh well, that’s a future collaboration effort to be worked on by wind industry executives and the Pennsylvania Game Commission once the generators have been installed.
It looks like harnessing natural energy may not be a panacea for America’s energy woes after all.
