How does a wind mill generate electric energy ?
potential energy of wind- rotation of wind mill- electrical energy
kinetic energy of wind- rotation of wind mill- electrical energy
solar energy- rotation of wind mill- electrical energy
heat energy of wind- rotation of wind mill- electrical energy
Kinetic energy of wind is used to rotate the wind mill which rotates the turbine and hence the dynamo generates electricity.
