Just finished The Bottomless Well:  The Twilight of Fuel, The Virtue of Waste, and Why We Will Never Run Out of Energy by Hubert & Mills.  It is fantastic.  Setting aside the seizures it causes in greens, which is a big selling point for me, the book actually has some really, really, really interesting information about the generation and distribution of energy in modern society, a subject with which I have always been fascinated but never really studied.
