Abstract

The paper examines the concepts of first-law (thermal) and second-law (exergy) efficiencies of power generation systems and the manner in which these efficiencies affect the economics of such systems. It is shown that, although the thermal efficiency may provide a preliminary indicator of the unit cost of the energy conversion equipment, it is generally a poor measure of the degree of success of the system in utilizing the input energy stream.
