Wind speed largely determines the amount of electricity generated by a turbine. Higher wind speeds generate more power because stronger winds allow the blades to rotate faster. Faster rotation translates to more mechanical power and more electrical power from the generator.The relationship between wind speed and power for a typical wind turbine is shown in Figure 2.

Wind power involves converting wind energy into electricity by using wind turbines.A wind turbine usually has three propellers-like blades called rotors. The rotor is attached to a tall tower. On average, wind towers in residential settings are about 20m high. The reason why the tower is so tall is that winds are stronger higher from the ground and there's less of a buffeting effect.
