Exergy analysis

The exergy of a commodity or flow is the maximum work that can be obtained from it as it passes reversibly to the environmental state, exchanging materials and heat only with the surroundings. Thus exergy is a measure of the ability to perform work. Exergy analysis exploits this notion and indicates the theoretical limitations governing a system.
