You probably have already seen the plastic wind mills that some homeowners use for their yard decorations. However, the wind mill is far more than just a decoration hundreds of years ago.

There are also some that use wind mills to convert mechanical energy into electricity.

Apart from being used as yard and garden decorations, wind mills can be used to generate free electricity. Modern homeowners can set up windmill outside of their house, or roof in some instances.
