Exergy - the maximum work that a thermodynamically open system can do in a given environment, going into equilibrium with the environment. The environment is treated as a container of useless energy and matter at constant temperature. Maximum energy is obtained in a reversible process.

The term introduced in 1955 by the Slovenian physicist Zoran Rant; ability to perform work - is a type of energy that can serve as a supply of energy; it is characterized by quantity and quality; It is destroyed when it is used.

Taking into account the possibility of occurring natural resources in nature, the definition can be formulated as follows: Exzergia expresses the minimum amount of work required to produce the required substance with the required parameters from the common elements of the surrounding nature, using the surrounding nature as a source of thermodynamically worthless heat.
