The Earth's major sources of energy will not last forever. Coal, oil and natural gas may all run out in the next fifty years. This book explains how the power of the wind is turned into electricity. It shows how wind power may be used to supply almost a quarter of our energy needs. It looks at how we could find new fuel supplies and develop new sources of energy.
