Wind energy has been used since hundreds of years. People have been using wind energy to move the sailboat or balloon, besides wind energy is also used to produce mechanical work, thanks to the windmill. The idea of using wind energy to produce electricity form shortly after the invention of electricity and generator. At the beginning of the windmill principle only small change and instead convert the kinetic energy of the wind into mechanical energy, use generators to produce electrical energy. When the flow mechanics department continues to develop, the construction equipment and the shape of the rotor is made more special. Today we call them wind turbines, windmills concept no longer relevant because they no longer have the crushing equipment. Since the oil crisis in the 1970s to study energy production from different sources to be promoted throughout the world, including the development of modern wind turbines.
