Wind turbine

 

A wind turbine is composed of a tower, 3 blades and a nacelle with all the mechanism. The wind turns the 3 blades and leads an engine wich transforms the wind energy into electricity. This electricity is stocks in batteries or sents to the electricity network of the companies of electricity. A wind turbine is very ecologic because it reject no pollution and it makes renewable energy. On a year, it works 3000 hours and produces 2 or 5 Megawatt. Every wind turbine reduces 20% of the CO2 emissions normally rejected. Wind turbines are placed on big zones without obstacles to get the wind : in the sea(offshore), on big lands, in mountains... You can have your own wind turbine but it's very expansive.

But there are a lots of disadvantages like: the landscape, the place, the aerial traffic, the noise , the conservation of the site...
