Dynamic Modeling Of The Energy Returned On Invested

This work was developed to present a conceptual and preliminary analysis of the concepts criteria for estimating Energy Return on Investment (EROI). In this work, methods based monetary studies, Life Cycle Analysis (LCA) were discussed dynamical systems modeling proposed. respect, we made mathematical development, defining state auxiliary variables adjustment parameters necessary study problem. Some influencing factors defined, in medium long term, sustainability energy system seek incorporate them into relevant areas discussion education, encouraging their dissemination reviews. It is sought discuss issues considerations standardized methodology that allows comparisons decision-making, order minimize environmental impact.
