Along with geothermal energy, solar energy is now one of the least environmentally disruptive sources of power by which electricity is generated today. Sunlight is a free, unlimited resource that hits the Earth with more energy in an hour than the people of the world use in a year. In Solar Power, readers will discover how scientists are trying to harness this power and explore potential developments into the future.
Because hydrogen fuel gives off water as a byproduct and does not emit any carbon dioxide, many people believe it could one day compete with oil as the major transportation fuel. In Hydrogen Fuel, readers will discover how this simple element can create clean energy, how it is used in the present for space shuttles and fuel cells, and how it may be used in the future.
Hydraulic power has been used for hundreds of years for everything from sawmills to steam generators. Water Power explores the past and present uses for this source of renewable energy and uses vivid photographs and illustrations to discuss its future in energy development.
From windmills used in the past to giant wind turbines that dot the landscape today, wind power has always been a prevalent, if intermittent, source of energy. Wind Power discusses the benefits of harnessing the wind for everyday use and its future as a renewable source of energy.
Though nuclear energy provides much more power than fossils fuels like coal, its use is hotly debated because of the potential for radiation seeping into surrounding areas. Still, it is widely used and has developed immensely in recent years. From its development to its environmental impacts, Nuclear Power discusses the positive and negative implications of this hotly debated source of energy.
