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. How can we find new fuel supplies and develop new sources of energy? Can we use the power of wind, water and sun to meet our energy needs?
This book explains how power can be produced from the natural heat of rocks, and from plants and household waste. It also looks at the energy of volcanoes and geysers.
