Environment, Power, and Society for the Twenty-first Century The Hierarchy of Energy

About this book

Environment, Power, and Society for the Twenty-first Century focuses on the significance of energy and its role in society. For this edition Odum refines his original theories and introduces two new quantities: emergy and transformity. These concepts evaluate and compare energy resources and their transformations by calculating all the energy and material that flows in and out of a particular system. Natural energies such as solar radiation, the cycling of water, carbon, nitrogen, and oxygen are diagrammed in terms of energy and emergy flow. Through this method Odum reveals the similarities between human economic and social systems and the way in which our survival and prosperity are regulated as much by the laws of energetics as by those of the physical and chemical world.
