 This paper proposes a framework for assessing the energy return on investment theory, which is a measure of how much energy is produced by a given source compared to the amount of energy required to produce it. The authors propose a dynamic systems modeling approach to estimate ROI, as well as a set of criteria and influencing factors that can be used to evaluate the sustainability of energy sources. They also suggest that these criteria should be integrated into relevant educational programs and policy discussions. This article was authored by Federico Gabriel Camargo.
