Wind Energy
From CopperWiki
Though wind energy has been harnessed since ancient times, its demand as an alternative energy source has been going since the initial oil shortages of the 1970s. Wind power plants, or wind farms as they are sometimes called, are clusters of wind machines used to produce electricity.
The kinetic energy of the wind can be changed into other forms of energy, either mechanical energy or electrical energy. Wind energy doesn’t use fuel, is pollution free and a sustainable form of energy.
