Wind power is a source of energy obtained by converting the kinetic energy of the wind into mechanical energy, which is in turn converted into electrical energy. Wind turbines are the generators of wind power and do not need fossil fuels to operate. The generators can be sited on-shore and near-shore, that is, more than 3 km from a coast, and therefore on dry land, or off-shore, at sea or on a lake.
The choice of location depends both on the amount of wind in the various areas and on the funds available, since off-shore installations are more expensive even though they are more productive. A group of generators in the same place is called a wind farm. The problems associated with it are mainly visual pollution, a possible risk to birds and dependence on weather conditions.
