The relevant bits are

I predicted that world oil production would peak on Thanksgiving Day, November 24, 2005. In hindsight, that prediction was in error by three weeks. An update using the 2005 data shows that we passed the peak on December 16, 2005. . . . . . By 2025, we're going to be back in the Stone Age. . . . . . . Ethanol, fuel cells, and solar cells are not the only shimmering dreams. Methane hydrates, oil shale, and the Yucca Mountain radioactive waste depository would be better off forgotten. There are plenty of solid opportunities. Energy conservation is by far the most important. Initiatives that are already engineered and ready to go are biodiesel from palm oil, coal gasification (for both gaseous and liquid fuels), high-efficiency diesel automobiles, and revamping our food supply. Every little bit helps, but even if wind energy continues its success it will still be a little bit. . . . . . . That's it. I can now refer to the world oil peak in the past tense. My career as a prophet is over. I'm now an historian.
