How can the varying output of the wind be used for generating electricity?
Wind energy is an intermittent resource. When the wind blows between about 7 meters per second (16 miles per hour) and 27 meters per second (60 miles per hour), wind turbines can generate electricity. When the wind doesn’t blow, or blows too hard, the turbines can’t generate electricity. Unfortunately, the wind doesn’t always blow when electricity is needed. Batteries can store only a modest amount of electricity to be used when the wind doesn’t blow.
