Wind power is a wind-dependent energy source. The sun heats the Earth unevenly, creating zones of different temperatures and atmospheric pressure around the globe. These differences in pressure give rise to air movements, called wind. This energy makes it possible to generate electricity in wind turbines, also called wind turbines, thanks to the force of the wind.
A wind turbine consists of 4 parts:
- The mast;
- The propeller;
- The nacelle that contains the electricity generator;
- The power lines that discharge and carry electrical energy (when connected to the grid).
It is an energy that emits no greenhouse gases and its raw material, the wind, is available all over the world and totally free.
