Net Energy Analysis and the Energy Requirements of Energy Systems
||6 1/8 x 9 1/4
With rising energy costs and the threat of diminishing resources affecting all international economies, the computation of energy required to extract and refine a resource--net energy analysis--has become an important component of energy analysis. This volume fills a major gap in the energy development literature by providing a full-length scholarly treatment of the subject. Written for energy researchers and managers in industries and utilities, Net Energy Analysis thoroughly explains the theoretical principles underlyiing net energy analysis, offers examples of how these principles are applied, and provides an impartial critique of current methods.

There were good things about the energy crisis of 1973--a sense of shared purpose, that any action that saved energy also benefited the environment, and that anything that saved energy really did. In time, we found that many of our strategies were not cost-effective and that others did not in fact lead to a reduction in total energy consumption. The energy investment exceeded the yield. Happily awash (again) in cheap oil, we forget the admonition reformulated by Spreng: `Every unintelligent, unorganized economic activity of large volume and high speed irreversibly deprives us of natural, cultural, and economic endowments that we cannot afford to lose in the long run.' Spreng brings an excellent background to his examination of the ways in which strategies for energy conservation are evaluated. Despite a scholarly chapter on thermodynamics, this is an economics monograph. It looks at several models for evaluation of energy conservation strategies and compares their results. The book is authoritative and reads well--even in an economy airliner seat. At one time, it provides an introduction to the field and a summation for those familiar with the literature.
