Coming to Bats..

March 23, 2018


Wind farms not only generate power but assist in long term environmental benefits.  The Journal of Wildlife Management reported that bats suffer from the benefits of wind turbines, primarily in Canada.  Researchers from Barclay-Baerwald discovered that most of the migratory bats in southern Alberta were killed by a decrease in atmospheric pressure caused by the rotation that occurs near the blades.  The speed of the blades impacts the bats’ lungs.  Biology professors at the University of Calgary reported that bats are more likely to fly when turbine speeds are relatively low. To reduce the fatalities without compromising energy  researchers successfully slowed the blades on 38 energy-producing turbines during low-wind periods. During peak wind periods that reap the most energy, bats don’t fly.
