THE HISTORY OF WIND ENERGY The first wind mill Wind power has been used as long as humans have put sails into the wind. Wind-powered machines was used to ground grain and pump water. Wind-powered pumps drained the polders of the Netherlands, and in arid regions such as the American mid-west or the Australian outback, wind pumps provided water for live stock and steam engines. A wind turbine is as loud as 105% lawn mover, 90% blender, 80% vacuum, 50% micro wave and 40% refrigerator Wind power doubled from 2006-2011 but non- reusable power only increased by 12% https://www.youtube.com/watch?v=niZ_cvu 9Fts
