Wind Power and Bat Lungs

Not only do wind turbines kill birds, which crash into the blades, but bats as well. This stands out because bats navigate by echolocation, which should alert them to the presence of the blades. Ed Yong reports on research into this at the University of Calgary. Examination of the bats’ bodies indicates that it is another mechanism responsible: bats entering the low-pressure zones created about the turbines have their lungs burst (“pulmonary barotrauma” is the technical term) due to the sudden pressure change.
