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 earth’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 earth’s terrain, it’s vegetative cover, and it’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.
