What is wind energy?
Wind energy is the most mature and developed renewable energy. It generates electricity by way of the strength of the wind using the kinetic energy produced by air currents. It is a clean, inexhaustible source of energy which reduces the emission of greenhouse gases and preserve the environment.
Wind energy has been used since antiquity to move sail-powered boats or drive windmill machinery by moving their blades. Since the early 20th century energy has been produced by way of wind generators. Wind energy moves a propeller and, by way of a mechanical system, it turns the rotor of a generator which produces electrical energy.
Wind generators are usually grouped into facilities called wind farms with a view to achieving a better use of the energy which reduces their environmental impact. The machines have a working life of twenty years.
