Mr. Huber talked about the book he co-authored with Mark Mills, The Bottomless Well: The Twilight of Fuel, the Virture of Waste, and Why We Will Never Run Out of Energy, published by Basic Books. He argued that the current push for energy conservation is not warranted because energy is not scarce, and that the excessive use of energy is necessary because a higher productivity rate warrants more jobs. After his presentation the author answered audience members' questions. Mr. Huber also wrote, Hard Green, Liability, and Galileo's Revenge.
