Our Finite World: "Many people when looking at future oil supply concern themselves with the amount of reserves (or resources) remaining, or perhaps Energy Return on Energy Invested (EROEI). None of these is really the right limit, however. The limiting factor is how long our current networked economic system can hold together. There are lots of oil reserves left, and the EROEI of Middle Eastern oil is generally quite high (that is, favorable). But instability could still bring the system down. So could popping of the US oil supply bubble through higher interest rates or more stringent lending rules."
