Georgescu-Roegen reintroduced into economics, the concept of entropy from thermodynamics (as distinguished from the mechanistic foundation of neoclassical economics drawn from Newtonian physics) and did foundational work which later developed into evolutionary economics. His work contributed significantly to bioeconomics and to ecological economics.

Exergy analysis is performed in the field of industrial ecology to use energy more efficiently. The term exergy, was coined by Zoran Rant in 1956, but the concept was developed by J. Willard Gibbs.

In recent decades, utilization of exergy has spread outside of physics and engineering to the fields of industrial ecology, ecological economics, systems ecology, and energetics.
