Plan B is not to be read as an introductory guide to sustainability. This book is perhaps best read by an audience with at minimum a passing background in sustainable development, and renewable energy. Lester Brown’s book does provide a dearth of statistics and data as to why wind, solar, and Geo-thermal energy are necessary for our modern society.  Additional factors threatening our civilization are covered as well such as epidemics and over population.

Overall Plan B presents a wealth of statistical evidence for the change Lester Brown recommends. I unfortunately believe that it was likely better to read this book in its v1.0 iteration, as at that time most of these subjects would barely have been filtering into everyday conversation. Even with most of the data having been updated for the current versions, the overall argument for incredible change by 2020 seems too close in time to accomplish all the suggestions put forth.

I do recommend anyone interested in furthering their knowledge on changing our global dependence on coal, oil, and natural gas should read the latest version of this book. And for anyone else seeking to gain a detailed knowledge of potential sustainable advances for our civilization this is a great tool.
