Input: EXCELLENT REVIEW OF THE ENERHY SITUATION . Very technical book with a great overview about energy and hydrocarbons in particular. I would not recommend this book as a first book about peak oil, this book is definately written for an audience that has more of a scientific background, but if you are concerned about the phenomenon of peak oil and have the ability to grasp basic scientific concepts, then this book is excellent. Not so much political as some of the other peak oil books, Deffeyes is a second generation petroleum man and a university professor. He deals with the fundamental aspects of peak oil as it relates to oil as a natural resource. Still, I believe that this book is essential reading to anyone trying to come to grips with the idea of peak oil and I highly recommend this book to all concerned people that can deal with the basic science involved. Peak oil is a fact, and everyone needs to understand the reasons why the human race needs to reduce our consumption of oil as soon as possible
Output:
POS
