Using of wind energy is not a new idea design. It was being using from long past but for the other different purposes than producing electricity. Wind power has been used since humans have put sails into the wind. For more than two millennia wind-powered machines have ground grain and pumped water. Wind power was widely usable and not confined. Wind-powered pumps drained the polders of the Netherlands, and in arid regions such as the American mid-west. With the development of electric power, wind power found new applications in lighting buildings remote from centrally-generated power. Throughout the 20th century parallel with the development of small wind plants suitable for farms or residences, and larger utility-scale wind generators that could be connected to electricity grids for remote use of power. Today wind powered generators operate in every size range between tiny plants for battery charging at isolated residences, up to near-gig watt sized of offshore wind farms that provide electricity to national electrical networks.
