I have read through these pages. Undoubtedly many of the things he states, particularly with respect to how long nuclear energy could supply us, are correct but only under the assumption that we don't continue to increase our usage of energy. It's hard to see how that assumption holds in a world that is continually growing its economies. Exponential functions grow very fast. (See http://www.youtube.com/watch?v=F-QA2rkpBSY)
You may then counter that a decoupling of economic growth from its material and energy underpinnings is possible. This has yet to be effectively proven. We have only seen partial decoupling so far. For more information on this see the writings of Tim Jackson in his book Prosperity without Growth.
I also urge you to download this spreadsheet (from the BP website) showing the growth in usage of fossil fuels (http://tinyurl.com/2yhx7d). We may find alternatives to these but if we do, we will have to bring the alternatives online at roughly the same level to supply our societies with the energy they now require to function. This is no easy feat. It's good know, quantitatively, just what's required.
