what are windmills used for

Windmills are used to harness wind power for useful work, most commonly grinding grain, pumping water, and generating electricity.

Quick Scoop

Historically, windmills were agricultural tools that helped communities process food and move water. Today, many modern windmills are really wind turbines, and their main job is producing renewable electricity for homes, farms, businesses, and even large power grids.

Common Uses

• Grinding grain into flour.

• Pumping water for irrigation or drainage.

• Generating electricity with a generator connected to the spinning blades.

• Supporting off-grid or rural power needs where regular electricity is limited.

Modern View

A simple way to think about it is: old windmills did mechanical work, while modern windmills mostly make power. The basic idea is the same in both cases: wind turns blades, and that motion is turned into something useful.
