The book was all beat up, but the seller said it would be. It was a ton cheaper than buying it new, though.

I got the exact book I was looking for. Also, it was shipped quickly which was perfect because I needed it for a class that had already started.

I've been teaching at a community college for 16 years in the field of energy efficiency, Passive solar, building science, healthy homes, sustainability, green issues. I have used this book and its earlier versions in my classes because it gives the best science basis for energy. It is also written by a physics professor as a textbook, with review and questions at the end of each chapter.

This book shows the "systems efficiency" of energy sources, which is the correct way to examine any proposed alternative energy. This is the way many of these topics is presented in other books. I like the book also because it starts at the beginning--physics--in the discussion of energy.

Energy provides comprehensive information on basic energy principles, electricity, fossil energy resources, nuclear power, renewable energy resources, energy conservation, and the impacts of energy use on the environment. While it contains all the requisite equations and problem sets, the concise, clear coverage of the environmental and policy issues surrounding our energy use really distinguishes this book from other energy texts.
