Long known as a potential power source, geothermal energy - heated water from within the Earth - is now being tapped. This book outlines those efforts and looks to the future.
We currently rely on nonrenewable sources, such as oil, for most of our fuel. Scientists are working on new fuels from crops and other materials to help ease future dependence on nonrenewable resources.
Many little-known facts about electric power - and the grid that controls much of it - are explained in this fascinating book.
The country's "addiction" to oil is described and alternative energy potential from hydrogen is discussed.
Recent advances in harnessing energy from the wind, sun, and tides are explored. People are encouraged to seek resources beyond fossil fuels.
For years, people have used water power to provide electricity. This study recaps that history and describes exciting new techniques.
Nuclear energy, with the potential to provide vast amounts of power, is a controversial topic. The science, history, and the controversy are explained here.
