Bats and Wind Energy Issue Brief

Hatchet Ridge, Pattern Energy

This four-page brief covers bat species that occur in the U.S. and Canada (including two species that feed on nectar, not insects); bat interactions with wind turbines (three species of migratory tree-roosting bats, which forage for insects at altitudes that put them in the vicinity of rotating turbine blades, make up approximately 80% of all wind turbine-related fatalities); legislation protecting bats; what we know about reducing bat fatalities from collisions with wind turbines; and what the future holds, particularly as wind expands in the Southeastern U.S. and turbines operate at lower wind speeds. The brief also includes an at-a-glance table of bat species characteristics.
