All societies run on energy. They all involve the collection of energy, the transformation of energy from one form to another, and the use of energy to take actions and make transformations. The social theory of energy, is scattered to put it mildly, and not much work has been done on it until fairly recently. This website suggests that understanding some basic features of the sociology and physics of energy is helpful to understanding technological transformation, and economic life. To understand the social life energy, people need to understand some of the laws of thermodynamics, where energy comes from, the importance of directable energy and available energy, and Energy return on energy input.
