Energy system efficiency in Cuba de composition analysis of energy use and co2 emissions

Eficiencia del sistema energético en Cuba análisis de descomposición del uso de energía y emisiones de co2

Resumen

This article presents results from a decomposition analysis of energy consumption and CO₂ emissions in Cuba during the period 1971–2019. Energy decomposition is done with a dynamic Sun-Shapley decomposition, which produces activity, intensity, and structural effects. CO₂ decomposition has been done with a chained two-factor decomposition, which provides effects identified in an extended Kaya identity. The results show that during this period, changes in sectoral energy intensities and the economic structure have decreased energy consumption slightly more than economic growth has increased it, but CO₂ emissions have not decreased correspondingly because of economic growth per capita and increasing carbon intensity of the primary energy mix. These kinds of scientific findings indicate that the energy efficiency policy in Cuba requires some more attention.
