Two major companies have formed a joint venture to construct towers for wind turbines in Cheyenne, Gov. Matt Mead announced Tuesday, Feb. 15, 2011.

Company officials say they intend to hire about 150 workers for the plant.(AP Photo/Star-Tribune, Tim Kuspick)
The use of wind energy is nothing new to the world, it has been around for centuries. The rotation of the earth, the irregularities of the earthâ€™s surface, and the uneven heating of the atmosphere by the sun, causes the wind. The motion energy of the wind, or the flow, is created by the earthâ€™s terrain, itâ€™s vegetative cover, and itâ€™s bodies of water.
Wind energy was used to move boats along the Nile as early as 5,000 B.C. Simple windmills were pumping water in China by 200 B.C. while vertical-axis windmills, with sails made from woven reeds, were grinding grain in Persia and the Middle East. Windmills appeared throughout Asia and Europe by the 1100s. Early ones were made of wood and were rotated by hand or oxen to assist the energy from the wind.
