Wind turbines have three main parts: Tower: Built on a sturdy foundation, a wind turbine’s tower may stand well above 100 feet tall. At that height the wind is likely stronger and more consistent, since it is not being deflected by trees and buildings. Also, the height prevents the blades from being a danger to livestock or other animals.
