Using a unique or common measure of energy poverty is very limited for the true classification of a household being in energy poverty. Thus, this study proposes a composite indicator, whose weights will be determined from the estimation of two relationships using a robust and stable methodology based on information theory. This work considers two regression models, where the two dependent variables are the gross domestic product and greenhouse gas, and the 12 energy poverty explanatory variables are based on those proposed by Recalde et al. (Energy Pol 133:110869, 2019. https://doi.org/10.1016/j.enpol.2019.07.005 ), for the period 2008–2018. Hence, the study presents a more comprehensive measurement with additional dimensions, weights, and indicators. Probably most important, in addition to the discussed proposal with a specific choice of models and variables, this work reveals a promising methodology that can be replicated in any other theoretical configuration. This approach is suitable for the discussion and design of new energy, environmental and social policies. Findings can be used to assess in advance the effectiveness of energy poverty measures, turning the model into a valuable policy tool.
