Wind turbines generate 2.7 billion kWh of electricity annually in California
providing about 1 percent of the state's electricity demands. A single turbine
can produce from 75 to 500 kilowatts of electricity.
The wind turbine generates electricity by the conversion of kinetic energy of the moving air into electrical energy. The movement of air past the blades forces them to rotate, which changes the magnetic feld within a set of coils, this principle is known as electromagnetic induction.
