A Territorial Estimate for Household Energy Vulnerability: An Application for Spain

This paper proposes a composite indicator intended to assess territorial differences in household energy vulnerability. Although the estimation of household energy vulnerability has received less attention in scientific literature than energy poverty, it is a key element for political action as it allows for the diagnosis and subsequent action to tackle potential situations of household poverty before they actually occur. In this sense, the principal contribution of this article is a proposal for a tool designed to quantify the abstract and multidimensional phenomenon of household energy vulnerability. The technique used for constructing this synthetic indicator allows for the participation of stakeholders, especially policy makers, in defining and calculating the index. The synthetic index for energy vulnerability has been estimated for Spanish provinces. The results allow for the creation of a map providing an approximate insight into the spatial distribution of household energy vulnerability in Spain.
