We have used the power from the wind to propel vessels for almost 7,500 years. The Chinese were using turbines to draw water from the ground around the year 200 B.C., while windmills became a useful tool for the grinding of grain in the Middle East. By the time we reached the Middle Ages, this technology was extensively used for food production.

Wind Energy

Wind energy is unique in how easily it can share land with other uses. In the U.S., around 90% of wind turbines are built on cropland or rangeland for grazing animals, most of it actively used. 9 In this sense, wind energy "takes up" hardly any land at all. Wind turbines can also be built offshore, sharing space with fishing and shipping.
