Wind energy is today considered one of the most promising natural sources of energy, mainly because it is renewable, ie not be exhausted. Moreover, the wind turbines can be used both in connection with electricity networks and in isolated places.


Portugal is one of the best places to set up wind mills capable of generating electricity due to the weather situation that we submitted. The windmills can be applied to the generation or production of electricity. In this case, the structure is only composed of a hollow rod or a metal frame, on top of which is a turbine. The blades are large, modern appliances in reaching between 40 to 90 meters in length and run slowly. The equivalent to the mast of the windmill hitherto described is directly connected to a generator element capable of converting the kinetic energy of rotation into electrical energy that is adjusted or corrected and then channeled to the common network for the supply of electricity.
This is a very efficient and clean way to generate electricity. Especially when the power plants are a major source of production of toxic waste and air pollution. Today it is clear that this form of energy production is increasingly common especially in our area where we see many windmills.
