How a Small Wind Electric System Works. Wind is created by the unequal heating of the Earth's surface by the sun. Wind turbines convert the kinetic energy in wind into clean electricity. When the wind spins the wind turbine's blades, a rotor captures the kinetic energy of the wind and converts it into rotary motion to drive the generator.

May 26, 2020· The wind turbines utilize the speed (kinetic energy) of the wind to make energy. The kinetic energy from the wind turns two or three propellers like blades around the rotor. The rotor has a connection with the main shaft of the turbine. This shaft then spins a generator to eventually produce electricity.

$begingroup$ If a windmill were capable of drawing power from the grid when spun backwards, then the grid would drive the blades backwards all the time! Also, the wind direction cannot spin the blades backwards. That would be a pretty poor windmill design. $endgroup$ – Colin K Jul 25 '11 at 14:43
