The Aeolian energy is the energy produced by the wind. The first use of the power capacity of the wind constitutes navigation to candle. In her, the wind force is used to impel a boat. Boats with candles appeared already in the older Egyptian engravings (3000 a.C.). The Egyptians, the Phoenicians and later the Romans had to also use the oars to resist an essential characteristic of the Aeolian energy, their discontinuity. Indeed, the wind changes of intensity and direction of unpredictable way, reason why it was necessary to use the oars in the periods of calm or when it did not blow in the wished direction. Today, in the Aeolian parks, the storage cells are used to produce electricity during a time, when the wind does not blow.

Another characteristic of the energy produced by the wind is its infinite availability in linear function to the surface exposed to its incidence. In the boats, to greater vélica surface greater speed. In the Aeolian parks, whatever more mills have, more power in tips of the power station. In the sailboats, the increase of vélica surface has mechanical limitations (the mast is broken or upsets the boat). In the Aeolian parks the only limitations to the increase of the number of mills are the city-planning ones.
