Energy and Exergy Efficiencies | Springer Nature Link
Energy and exergy efficiencies are considered to be useful for the assessment of energy conversion systems and for improved performance. By considering both of these efficiencies, the

Exergy, often referred to as "available energy" or "useful work potential", is a fundamental concept in the field of thermodynamics and engineering. It plays a crucial role in understanding and quantifying the quality of energy within a system and its potential to perform useful work. Exergy is a combination propertyof a system and its environment because it depends on the state of both and is a consequence of dis-equilibrium between them. Applying equation (1) to a subsystem yields:This expression applies equally well for theoretical ideals in a wide variety of applications: CarnotIn 1824,studied the improvements developed forbyand others. Forms of energy such as macroscopic kinetic energy, electrical energy, and chemicalare 100% recoverable as work, and therefore have exergy equal to their.
