A windmill is a type of engine. It uses the wind to make energy. Usually, a windmill is a large building. Common types of windmills are post mills, smock mills and tower mills. The energy made by windmills can be used in many ways. These include grinding grain or spices, pumping water and sawing wood. Modern wind power machines are used to create electricity. These are called wind turbines.

A windmill is a mill that converts the energy of wind into rotational energy by means of vanes called sails or blades.[1][2] Centuries ago, windmills usually were used to mill grain, pump water, or both. Thus they often were gristmills, windpumps, or both.[3] The majority of modern windmills take the form of wind turbines used to generate electricity, or windpumps used to pump water, either for land drainage or to extract groundwater.
