Windmill - Wikipedia

A windmill is a mill that converts the energy of wind into rotational energy by means of vanes called sails or blades. Centuries ago, windmills usually were used to mill grain , pump water , or both. There are windmills that convert the rotational energy directly into heat. The majority of modern windmills take the form of wind turbines used to generate electricity, or windpumps used to pump water, either for land

Why Can't We Generate All Our Energy From Wind Power?

Why not just build lots and lots of them until we produce enough power, thus solving the problems caused by dirty power plants? Sadly, as is often the case, reality is a bit more complex than that. To answer this question, we need to better understand how wind power works, and how a power grid works.
