About Wind Turbines

an old dutch style windmill


A wind turbine is a rotating machine that seeks to convert the kinetic energy present in the wind into mechanical energy. If particular machinery like a pump or grinding stone uses the mechanical energy in a direct manner then it is called a windmill, however, if this mechanical energy is first converted into electricity and then used, then the machine is commonly called a wind turbine or a wind energy converter amongst other things.

History of Wind Turbines


The first wind machines were used in Persia, as far back as 200 B.C for the purposes of grinding grain. By 250 A.D the Romans began to use the same process for the same purpose. The Dutch started using windmills to drain water from the areas lying in the Rhine River delta.
