Since the discovery of fire, humans have been energy users. And this is a good thing--our mastery of energy is what separates us from the rest of the animal kingdom and has allowed us to be the dominant species on the planet. However, this mastery comes with a price: we are changing our environment in a profoundly negative way by heating it up. Using one engaging story after another, coupled with accessible scientific facts, world authority Richard B. Alley explores the history of energy use by humans over the centuries, gives a doubt-destroying proof that already-high levels of carbon dioxide are causing damaging global warming, and surveys the alternative energy options that are available to exploit right now. These new energy sources might well be the engines for economic growth in the twenty-first century.--From publisher description.

From the Publisher: Green Technology is an eight-volume set that examines the relationship between human activities and their sometimes harmful consequences for the environment and explores new methods of repairing and restoring the Earth. Approaching environmental issues confronting society from a technological perspective has spawned significant controversy, and the books in this set present all sides of the debate. Designed to complement science curricula, the set also covers relevant history and new green technologies and innovations that will contribute to the field in the future. Environmental Engineering: Designing a Sustainable Future examines how this field, which incorporates not only aspects of art and design but also physics, geology, ecology, and the chemistry of matter, evolved from a discipline of civil engineering. Environmental engineers learn how to work with nature to improve and control the quality of the land, air, and water for the benefit of human and nonhuman cohabitation. Sidebars, figures, and case studies enhance fundamental concepts and examine urgent issues related to the "natural future" of the environment. The volume includes information on: aerodynamics; ecological and energy "architecture"; energy-efficient electronics; innovations in personal vehicles; landscape design; micro climates; solar homes; sustainable manufacturing; transit systems; and wastewater. The book contains 50 color photographs and line illustrations, five appendixes, a glossary, a detailed list of print and Internet resources, and an index. Green Technology is essential for high school students, teachers, and general readers who seek information on the important issues that affect the environment worldwide.
