Compelling responses to Peak Oil skeptics from Matt Simmons:

Oil's recent slide and the slackening demand that an economic slowdown's expected to bring have stimulated hopes that crude could soon safely stabilize below the $100 range.
But beneath seesawing supply and demand lies the deeper question of just how much oil the planet has in the first place — and how much it will have in the future.
The answer to that question supports — or undermines — the theory that we are in the midst of an ever-tightening supply that will lock prices into a permanent, rising arc. That, in nutshell, is what's meant by the term "peak oil".
