The term "exergy" was coined in 1956 by Zoran Rant (1904–1972) from Greek ex- ("out of", "away from") + ergon ("work").
- (physics) Concentrated or organized energy, which can be exported and do work in the process.
- The maximum fraction of an energy form which (in a reversible process) can be transformed into work is called exergy. The remaining part is called anergy, and this corresponds to the waste heat.
- To be useful, internal energy has to be concentrated. The more dilute or disorganized the internal energy, the less useful it is ...
- bound energy
