Why do people use wind energy?
Ingrained in our world history, people have been using wind energy for thousands of years. As early as 5,000 BC, wind was used to propel boats along the river Nile. In 200 BC, wind-powered water pumps were being integrated in China and windmills were grinding grain in the Middle East.
