"In its particular niche this is the best book of which I am aware. I would like to compliment the authors for their concise and sure-handed discussion of a host of difficult topics."--Russ Houldin, University of Toronto"The strength of this book may lie in the fact that it presents concise and accurate information with very well-organized chapters covering almost all aspects of energy and the environment. The chapters on topics such as fossil-fueled power plants and nuclear-fueled power plants as well as transportation, are well-written."--Chunbao (Charles) Xu, Lakehead University
