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.

Hybrid cars, which run on alternative energy sources like sunlight, corn, and biofuels, may be the key to using less oil. This title discusses how these machines work, the science behind the energy they make, and what the use of hybrid cars means for the planet.
