Remember that wind power is all that is obtained from wind and is transformed into other forms useful for activities human.
Wind energy is obtained from wind turbines. These are a few power generators, which are driven by a turbine which in turn is driven by the wind . They use a system similar to its predecessors, the windmills. They are so similar to these General and vulgar terms typically call these windmills.These generators are considered to be a source of clean energy, renewable, since for energy production do not require a combustion which produces polluting waste. Thus we can say that a wind farm does not contaminate the environment, becoming the means of energy production more clean has discovered the man.As we have said before, a wind farm might be the means of energy production more clean that it exists. But we have not made clear they are wind farms. These are a set of wind turbine that transforms wind power into electricity .Wind farms are often built in open spaces, ground surfaces both in the water. Is more common to find on Earth, but it seems that in recent years it has popularized the build in the sea, supposedly because the sea floor will not be as expensive as the of land.To build a wind farm, are very considered dissimilar existing soil and the environment. It is usually take time important to take the necessary measures to make it conducive to build a wind park, takes into account especially the direction and power of the wind.In spite of all this is beginning to have a wind farm in the sea is much more efficient. Here is the link to an interesting article where carefully explains how to build a wind farm in the sea.
If we look at a general level the situation in Europe . The largest investors in wind farms are: Germany, Scotland, Spain and Portugal.
