Harnessing energy from the wind dates back to sometime around 5,000 B.C.E. when sails were used to propel boats along the Nile River. Windmills began pumping water in China in 200 B.C.E., and were used to grind grain in Persia.
Windmills have served many purposes as an energy source. In Holland they mainly pumped water from low-lying areas so the area could be farmed.
Wind’s use as a source of electricity is of course much more recent. And its potential to meet energy needs in the U.S. is only beginning to be exploited as a non-polluting, renewable source of energy.
