It examines the complex issues surrounding existing and potential energy sources, including the world's current dependence on nonrenewable resources of energy, the increasing need for energy, the impact on the environment of current energy sources, and implications for the future. Each volume begins with the same Glossary and Overview. Pagination follows that of previous volume. VOLUME 3 focuses on water and wind energies and explores the move towards more energy-efficient tools, appliances, building materials, and vehicles.
