Wind turbines use blades to collect the wind's kinetic energy. The blades are connected to a drive shaft that turns an electric generator, which produces. . Wind turbines work on a simple principle: instead of using electricity to make wind—like a fan—wind turbines use wind to make electricity. Wind is a form of solar energy caused by a. . Wind energy is the kinetic energy of the motion of a large mass of air on the surface of the Earth, which is produced by the non-uniform heat of the Earth's surface by the Sun. The diagram of the wind turbine above is a side view of a horizontal axis wind turbine with the turbine blades on the left. Clustered in wind farms across large. .
