These are very brave words for and by an industry that is still using primary and secondary methods for extraction. Primary means the pressure is high enough that it literally shoots out of the ground. That's pretty easy oil. Secondary means employing a mechanism -- like a pump -- to get it out of the ground. We're just now beginning to toy with new tertiary methods of extraction, and they are expensive. Yes, innovation marches on. However, we probably won't innovate planet-scale hydrocarbon supplies out of thin air in the next twenty five years. The price will keep getting higher, the methods more and more creative, but at some point, capitalism as a mechanism for oil extraction becomes ineffective (and eventually impossible), and the flow of oil stops. Whether or not we have another equally "free" source of energy standing by to take over is another issue altogether.
