 Wind is a form of solar energy. Winds are caused by the uneven heating of the atmosphere by the sun. Wind 
 flow patterns are changed by the earth’s terrain, bodies of water, and vegetative cover. This wind flow, or 
 motion energy, when “harvested” by modern wind turbines, can be used to generate electricity. 
 Wind turbines are available in a variety of sizes, and therefore power ratings. The largest machine has blades 
 that span more than the length of a football field, stands 20 building stories high, and produces enough 
 electricity to power 1,400 homes. A small home-sized wind machine has rotors between 8 and 25 feet in 
 diameter and stands upwards of 30 feet and can supply the power needs of an all-electric home or small 
 business, utility scale turbines range in size from 50 to 750 kilowatts. Single small turbines, below 50 
 kilowatts, are used for homes, telecommunications dishes, or water pumping.
