Awindmill converts the mechanical energy of wind into energy produced by a generator

A windmill converts the mechanical energy of wind into  electrical energy produced by a  generator

Explanation:

The wind that hits the windmill has kinetic energy, that is a form of energy related to the motion of the wind. This type of energy is also classified as part of the mechanical energy of the wind (mechanical energy is the sum of potential energy and kinetic energy of an object).

The windmill is put in rotation by the wind, and this makes a loop of wire rotating inside a permanent magnetic field: as a result, an electrical current is induced in the generator of the windmill. This electrical current carries electrical energy, therefore we can say that the initial mechanical energy of the windmill has been converted into electrical energy.
