उत्तर
It works on the principle of conversion of the kinetic energy of blowing wind into electrical energy. When the blowing wind strikes across the blades of a windmill it exerts a force that rotates its blade. The turning of the blades would simultaneously cause the shaft to turn, which is connected to a generator. This makes the generator produce electricity.
