It is also called available energy
property which enables us to determine the useful work
potential of a given amount of energy at some specified state
example: -
When a new energy source, such as a geothermal well, is discovered, the first thing the explorers do is estimate the amount of energy contained in the source. This information alone, however, is of little value in deciding whether to build a power plant on that site. What we really need to know is the work potential of the source—that is, the amount of energy we can
extract as useful work. The rest of the energy is eventually discarded as waste energy and is not worthy of our consideration.
Exergy helps in determining the work potential of a source

The usable energy in a system is called exergy, and can be measured as the total of the free energies in the system. It is a term used to describe differences in energy quality. The exergy content of a system indicates its distance from thermodynamic equilibrium. The higher the exergy content, the farther from thermodynamic equilibrium.

Good luck!
Hope it will help!
