Combining energy efficiency with renewable energy resources constitutes a key strategy for a sustainable future.
Many countries, especially Europeans, have invested significantly in this type of energy because it is clean, does not cause air pollution, does not produce or use radioactive material and is inexhaustible. Portugal is one of those countries. At the end of 2007, it was the tenth world producer of wind energy.
Wind power is the conversion of wind energy into a useful form, such as electricity, using wind turbines.
At present, wind energy is used to move aerogenerators - large turbines placed in windy zones. These turbines have the form of a windmill. This movement, through a generator, produces electricity.

They need to be grouped in wind farms, concentrations of aerogenerators, necessary for the production of energy becomes profitable. But it can be used alone to feed and remote locations away from transmission network.
When it comes to size, bigger is better – the bigger the wind turbine, the more wind it reaches and the more electricity it produces.
Wind power is a very good option in which countries must rely more and more. It is an excellent alternative to fossil fuels as well as other energy that we will talk.

I believe that we may have a better world if we rely a lot in wind power, because it's not very expensive and it's "green".
