Though bats have excellent hearing and eyesight, bats primarily use echolocation when navigating their surroundings and foraging for food. By changing how wind turbines are managed and developing acoustic deterrents to discourage bats venturing near the spinning blades, BCI has high hopes that the wind industry can be sustainable not only for our climate, but the future of our bat species as well.
