What is wind energy?

    Wind energy is an energy source that depends on the wind. The sun heats the Earth unevenly, creating zones of different temperatures and atmospheric pressure around the globe. These pressure differences arise from the movement of air, called wind. This energy is used to produce electricity in wind turbines, thanks to the strength of the wind.

A wind turbine is composed of 4 parts:                                             

1. the mast
2. The propeller
3. The nacelle containing the electricity generator alternator
4. Electric lines that evacuate and transport electrical energy (when connected to the network)

Down the windmill Middle Ages, the first wind turbine was commissioned in Franch at Dunkerque in 1990.
