CAMARGO, Federico Gabriel. Dynamic modeling of the Energy Returned On Invested. Dyna rev.fac.nac.minas [online]. 2022, vol.89, n.221, pp.50-59.  Epub Aug 29, 2022. ISSN 0012-7353.  https://doi.org/10.15446/dyna.v89n221.97965.

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

Keywords : primary source of renewable generation; life cycle analysis; energy return on investment.
