Windmills are able to convert mechanical energy into electric energy. Mechanical energy is created when wind blows against the blades of the windmill which then begins to rotate because of the difference in air pressure. Each windmill will have many huge blades that generate a lot of power when rotated.

Inside the windmill, there is a shaft that is connected to the blades and the generator. The generator is the device that converts the mechanical energy created by the blades into electrical energy for use in the home.
