I saw the review you posted when it was first published. I will comment on a
couple of things.

I absolutely agree that Hubbert's methodology is much better with
unrestricted exploration, production and with no economic downturns. But
that doesn't fundamentally change the reality that there is only so much oil
in the earth to extract. The North Sea has had 2 peaks of production. The
first downturn was because of the price collapse in 1986. This last one has
been due to the oil running out. Mexico looks like it peaked out a couple
of years ago, but it is due to lack of investment. Mexico has huge potential
left which their political system isn't allowing to be exploited. But that
being said, it doesn't change the fact that the world for 20 years has been
pumping more oil out of the ground than we have been finding. How long does
anyone really think that can continue?

I would point out that very few in the oil industry believe that
100-personyear report. Mere human labor doesn't make a government
Robertson REseach over here studied half the oil basins in the world and
predict that the world production will peak in 2008. They also spent
100-manyears or so in effort. And their assessment sounds much more
realistic to me. I have to go to work now, but I will try to find the url
for that report.
for lots of creation/evolution information
