Energy resources: Wind energy
Wind energy was the fastest growing power source at the start of the 21st century, yet wind-driven mills and pumps, and nautical sails for transport, were, along with waterwheels, the first mechanical devices to power industrial production. The advantages of harnessing wind energy are obvious; it is free, clean and widely available. This free course, Energy resources: Wind energy, explores wind as a potential source of useable energy.Author(s):
