Energy Resource:Wind Power

We've used the wind as an energy source for a long time.

The Babylonians and Chinese were using wind power to pump water for irrigating crops 4,000 years ago, and sailing boats were around long before that.

Wind power was used in the Middle Ages, in Europe, to grind corn, which is where the term "windmill" comes from.
