Can Bats and Wind Power Get Along?

New research finds that an adjustment to wind turbines could allow bats and wind power generation to better co-exist. Writing in in the Journal of Wildlife Management, biologists report that that slowing turbine blades to near motionless in low-wind periods significantly reduces the number of bat deaths. The researchers said that since few bats fly during the higher wind-speed periods of most interest to energy producers, the blades could be slowed during low wind-speed times when more bats are aloft at relatively low cost to power production. We'll talk about the report and the challenge of integrating wind power into the environment.
