Simple models for the consumption rate of fossil fuel

Energy consumption models are useful in the analysis of many energy and resource problems. Fossil fuel consumption models are especially useful in forecasting future atmospheric CO2 levels. Simple models are frequently used to develop scenarios. In CO2 analysis, two logistic type models have been used to construct scenarios of fossil fuel consumption. In this paper, economic theory is used to derive a new model. The previous logistic type models are shown to be special cases of the new model.
