Energy Systems and Environmental Education
An overall systems view of energy flows can be used to teach the important basic principles for understanding the environment. One way of teaching energy, systems, environment, and economics as a unified whole uses energy symbols (Fig. 1). The method can be taught in a single college course, as part of more traditional courses, or in a special short course. It includes methods of energy evaluation of the environment, so the environment is given an economic value which can be compared to the values of other parts of the economic system. The textbook used is Energy Basis for Man and Nature with an Instructor’s Manual by H. T. and E. C. Odum, McGraw-Hill Publ., 1976. The following are some of the points we make using energy language in our course.
