Christopher Steiner. $20 Per Gallon: How the Inevitable Rise in the Price of Gasoline Will Change Our Lives for the Better. New York: Grand Central Publishing, 2009. 275 pages. This is an excellent study of the gradual effect on our way of life of the rising price of oil and gasoline. As gas rises from $4 to $6 and on up to $20, the author describes how we will adjust, by densifying our cities and abandoning sprawling suburbs and some small towns. Cars will become very expensive, electric cars will rule, air travel will become only a luxury. Subways and trains will have to be built to match those in Europe and Japan. The value of this book is that the facts are presented in a very matter-of-fact, understandable manner, and yet the science behind it is not simplistic. So the problems and conclusions propounded have all the impact found in peak oil guru James Kunstler's books, but without the bombast. This book should be required reading for every American.
