What is correct way to model the future course of energy and the economy? There are clearly huge amounts of oil, coal, and natural gas in the ground. With different approaches, researchers can obtain vastly different indications. I will show that the real issue is most researchers are modeling the wrong limit.
Most researchers assume that the limit that they should be concerned with is the amount of oil, coal, and natural gas in the ground. This is the wrong limit. While in theory we will eventually hit this limit, because of the way fossil fuels are integrated into the rest of the economy, we hit financial limits much earlier. These financial limits include lack of investment capital, inability of governments to collect enough taxes to fund their programs, and widespread debt defaults.
