Ummm . . . windmills use the wind to keep them turning. No biofuels are involved.
Use as gas
source:(http://en.wikipedia.org/wiki/Biofuel)we use biofuels because they do not make as much pollution as normal fuels.
err....yea.... windmills use wind, clue is in the title
Windmills use wind energy.
Biofuels
If they are diesel powered they can.
In order to grow the crops required to produce biofuels more forests need to be knocked down to make the necessary fields.

The steady increase in carbon dioxide concentrations in the atmosphere come from our use of fossil fuels. If we were able to stop using fossil fuels, the amount of carbon dioxide in the atmosphere would stop rising. Biofuels are a partial answer, because by using biofuels you are reducing our use of fossil fuels.
Biofuels are fuel made from any plant or animal based products. Two traditional biofuels are wood and corn. Biofuels are renewable sources of energy.
Windmills transform the kinetic energy of the moving air mass into other energy forms.
No. Windmills use the wind for various puposes such as grinding grain, pumping water, and generating electricity.
