San Gorgonio Pass, Riverside County, California. Electricity generators powered by wind turbines. Wind turbines are tall and are placed on hills or by the sea so that they receive as much wind as possible. This is because the power which they generate increases with longer blades and higher wind speeds. Most machines are designed to operate in windspeeds between 21 and 60 kilometers per hour.
