Exergy energy
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 property of 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 for by and others. Forms of energy such as macroscopic kinetic energy, electrical energy, and chemical are 100% recoverable as work, and therefore have exergy equal to their.
