Wind energy

Wind energy has been used since antiquity to move the boats driven by candles or to operate the machinery of mills, to move their blades. In windmills in the wind energy was converted into mechanical energy is used in the milling of grain or to pump water. The windmills were used for the production of flour and also for drainage channels, in the Netherlands.
In actuality, is used in wind power to move aerogenerators - large turbines placed in positions of much wind. These turbines is in the form of a weathervane or a windmill. This movement, through a generator, producing electricity. They need to be grouped in wind farms, concentrations of aerogenerators, necessary for the production of energy becomes profitable, but can be used alone to feed remote locations and distant transmission system. You can still aerogenerators the use of low-voltage requirements in the case of limited electric power. 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 electrical networks in places such as isolated.
