The Role Of Energy In Economic Growth
Physics shows that energy is necessary for economic production and, therefore, economic growth but the mainstream theory of economic growth, except for specialized resource economics models, pays no attention to the role of energy. This paper reviews the relevant biophysical theory and mainstream, resource economics, and ecological economics models of growth. A possible synthesis of energy-based and mainstream models is presented. This model shows that when energy is scarce it imposes a strong constraint on the growth of the economy but when energy is abundant its effect on economic growth is much reduced.
