What is it?
Wind energy results from the use of the kinetic energy of the wind to produce mechanical energy, which is later transformed into electrical energy by a generator. Wind has been used for thousands of years to meet the energy needs of human activities, namely to propel means of transportation (sail boats and ships), pump water or allow industrial activities to take place.
Wind energy is a way of obtaining electricity using 100% clean sources, which keeps any type of pollutant from being produced. Wind energy is a renewable energy source obtained through solar energy – in other words, it has its origin in the heating of the atmosphere by the Sun, which puts air masses in movement. The Earth’s rotation, and the form and cover of the Earth’s surface and bodies of water, influence the speed, direction and variability of the wind in any given spot.
Wind energy has increasingly come to be used to produce electricity, both for local, decentralized use in isolated places and in large wind farms made up of a number of wind turbines connected to the electricity grid.
