Originally published in 1984, this book discusses the structure of a multi-sectoral, general equilibrium growth model of the US economy that gives special attention to the energy sectors and presents results from the simulation of this model under varying conditions of energy supply. While the book primarily analyzes the effect of energy supply on economic growth, it also presents a new methodology for approaching this kind of problem, but this same approach can be used to model the effect of changes in the supply of any produced raw material on economic growth.
