Illustration 2: Principle behind.horizontal windmill illustration,The Inside of a Wind Turbine | Department of Energy. wind turbines use wind to make electricity. The energy in the wind turns two or three propeller-like blades around a rotor. The rotor is connected to the main shaft, which spins a generator to create electricity. This illustration provides a detailed view of the inside of a wind turbine, its components, and their functionality.

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 (gristmills), pump water (windpumps), or both. The majority of modern windmills take the form of wind turbines used to generate electricity,.

Windmill for Kids - Kiddle

An organ powered by a windwheel was written about in the 1st century AD by the Greek engineer Hero. It could have been the first machine in history that used wind power. Vertical axle windmills were used in eastern Persia (Sistan) by 60 AD. Horizontal axle windmills were invented in Northwestern Europe in the 1180s.
