In thermodynamics, the exergy of a system is the maximum useful work
possible during a process that brings the system into equilibrium with a
heat reservoir. When the surroundings are the reservoir, exergy is the
potential of a system to cause a change as it achieves equilibrium with
its environment. Exergy is the energy that is available to be used.
After the system and surroundings reach equilibrium, the exergy is zero.
Determining exergy was also the first goal of thermodynamics. The term
"exergy" was coined in 1956 by Zoran Rant by using the Greek ex and
ergon meaning "from work", but the concept was developed by J. Willard
Gibbs in 1873.
