Abstract

El objetivo de este estudio es identificar los factores determinantes del consumo eléctrico de los hogares, que deberán tenerse en cuenta en la definición de políticas de ahorro energético. Para ello, y a partir de los datos de la Encuesta de Presupuestos Familiares, se estima un modelo econométrico de demanda eléctrica utilizando la metodología de la regresión cuantílica, que se presenta como una herramienta más potente en la estimación de relaciones causales cuando se trabaja con datos procedentes de encuestas con tamaños muestrales elevados y ante la presencia de heterocedasticidad y/o datos atípicos. Los resultados permiten definir a la electricidad como un bien de primera necesidad, con una elasticidad renta próxima a cero, y donde cualquier política de ahorro energético que implique variación en la renta disponible tendrá un impacto muy limitado en los hábitos de consumo eléctrico. The aim of this study is to identify the determinants of household electricity consumption, to be taken into account in the definition of energy saving policies. Using microdata from Household Budget Survey in Spain, an econometric model of electricity demand is estimated using the methodology of quantile regression, which is a more powerful tool in the estimation of causal relationships when working with data from surveys with sample sizes higher and presence of heteroscedasticity and/or outliers. The results allow us to define the electricity consumption as a necessary good, with an income elasticity close to zero, and where any energy-saving policy that involves change in income will have a limited impact on electricity consumption habits.
