I actually thought his energy vision was pretty off the mark. Oil won't peak when when we'll be able to extract less than before. It will peak when electric cars will start becoming mainstream, and I expect that to happen at least a decade earlier, with most cars "in production" being electric cars happening about 2 decades earlier (so about 10 years from now).

He completely dismisses solar power, even though it has seen accelerated decrease in price/Watt already, in some countries/regions even surpassing coal-based energy in price, and it's still very early days. I also have quite opposite views about fission. If we figure out fusion, we might use that quite a lot, but I really doubt everyone will use an order of magnitude more fission reactors than we do now to power the 3d-printing and space economy.
