Leggett, Jeremy. The empty tank: oil, gas, hot air, and the coming global financial catastrophe. New York: Random House, 2005. ISBN 1-4000-6527-5.

Summary: The author, formerly a geologist for a major oil company, now an environmental activist, collates and explains the evidence for his view that two catastrophic oversights are about to catch up with us: (1) the supply of oil has peaked, or is about to, so that oil products will be more expensive and, eventually, scarcer in the future; and (2) burning fossil fuels is increasing the amount of carbon dioxide in the atmosphere, which in turn is rapidly warming up the planet.

Since we have wasted at least fifteen years pointlessly denying or ignoring these facts, it is now too late for us to make a graceful transition to renewable energy. The author believes that we will eventually move to solar, geothermal, wind, and hydroelectric power, but not until after the stock market crash and ensuing economic depression, and possibly not until after we have flirted disastrously with trying to use coal as a replacement for oil. The good news is that we will probably be able to make the transition in about a decade whenever we finally get around to taking our heads out of our asses.
