Is Peak Oil upon us?

Thanks to WorldChanging (still, by the way, my favorite blog), a link to today's essay from The Oil Drum titled "Why peak oil is probably about now". Which is really all that it says it is.

Since the immediacy of peak oil is--at best--a controversial proposition, anyone who knows of a comprehensive and sensible rebuttal to such claims can feel free to throw a link my way so I can throw it out. If such rebuttals are lacking, however, those with piles of cash money lying around may wish to look at another WorldChanging post from today, Investing in Alternate Energy.
