Exergoeconomic factor

Definition

The exergoeconomic factor is a measure that combines exergy analysis with economic assessment to evaluate the performance and efficiency of energy systems. It helps in identifying not only how much useful work is produced but also how cost-effective the energy conversion processes are. This concept integrates thermodynamic principles with economic implications, enabling better decision-making in system design and operation.
