Wind turbines are rotating machines made for the sole purpose of turning kinetic energy generated by wind into a renewable source of mechanical energy; which in turn can be used for other purposes, such as converting into electricity. Direct use of that mechanical energy makes the machine a wind mill, while conversion to electricity renders it a machine called by any of the following names: wind generators, wind turbines, wind power units (WPU), or wind energy converters (WEC). The basic technology have been in use for many centuries now, but the main focus for this seemingly-ancient technology
