4. General conclusions

Every energy system interacts with its physical environment and the economic environment in which it operates.

Only exergoeconomic analysis, based on the union between the thermodynamics of irreversible processes and economic analysis, takes into account the interaction with these two environments.

Exergoeconomics is the only method capable of taking into account losses to the environment as well as internal destruction, and assigning them an economic cost.

The search for an optimal functional and constructive solution, based on the principles of exergoeconomics, provides the direction for improving system structure that no other optimization method can provide.
