What energy is used in wind farms?

When wind, a natural form of energy, is able to create electricity or mechanical force, it is wind force. According to windmills, wind turbines (also called wind turbines) use wind energy, which they convert into electricity. The wind speed turns the rotor blades (10 to 25 rpm). The rotor then turns a generator, which converts mechanical energy into electricity. Each turbine consists of a mast from 20 to 100 m, depending on the power of the machines. The mast supports a rotor, usually equipped with three blades, and a nacelle that contains a generator and an electrical and mechanical backup system.
