Focusing on climate change and related policies, Sadler (Western Illinois Univ.) analyzes energy markets and systems and evaluates the usefulness of individual energy resources. Part 1 provides an understanding of the basics of energy economics, part 2 concentrates on traditional energy resources (oil, coal, natural gas, nuclear), and part 3 examines challenges to policy that controlling climate change presents. Sadler points out that the energy system comprises six sectors—electricity generation, power sources, fuels, buildings, industry, and transportation—and reminds readers that gains in energy efficiency across these sectors require changes in technology and human behavior. Addressing the climate change problem requires getting away from fossil fuels and learning to produce electricity with natural gas and renewables, and Sadler observes that credibly taking on climate change demands clean energy transformation. . . the book covers topics in energy economics sensibly and will serve as a useful resource for readers seeking an introductory treatment of this subject. Summing Up: Recommended. Lower-division undergraduates through faculty; professionals.
