The Energy Mix Concentration Index (EMCI)is a quantitative indicator of concentration of the energy mix based upon the Herfindahl-Hirschman Index. We use the EMCI to compare the evolution of the diversification (versus concentration)of energy mixes in the long-term in order to reveal the transformations of the energy structures which determine energy transitions.

The Energy Mix Concentration Index (EMCI)is a quantitative indicator of concentration of the energy mix based upon the Herfindahl-Hirschman Index. We use the EMCI to compare the evolution of the diversification (versus concentration)of energy mixes in the long-term in order to reveal the transformations of the energy structures which determine energy transitions. In this methodological paper we make explicit how to aggregate the energy sources in order to calculate the EMCI, including questions of detail such us the level of aggregation and the transformation of primary electricity to add it up to total consumption. We present alternative figures that illustrate some additional aspects of the relation of the EMCI to total consumption, consumption per capita and energy annual growth. We also show the sensitivity of the indicator to alternative specifications (with and without pre-modern energy sources)and alternative data sets, proving its robustness. Indicate how to aggregate energy carriers in the calculation of a quantitative index of concentration of the energy mix. Compare alternative specifications (with or without pre-modern energy carriers). EMCI focus on the major energy sources in the energy systems. [--]

200 years diversifying the energy mix? Diversification paths of the energy baskets of European early comers vs. latecomers Rubio Varas, María del Mar ; Muñoz Delgado, Beatriz (Universidad Autónoma de Madrid, 2017) Documento de trabajo / Lan gaiakThe changes in the composition of the energy basket in the long run lead to energy transitions. Primary energy substitution models allow addressing these phenomena. However, the diversification paths of the energy mix of ...
