I. Introduction
Eurostat data indicate that 22.4% of the EU population is at risk of poverty or social exclusion [1]. This massive problem, which is unevenly distributed across Europe [2], is difficult to fight as a whole without substantial changes in the economic system. However, as poverty has multiple effects on people suffering it (health, social, energy, financial, etc.), regions and countries began to distinguish among forms of material and monetary deprivation in order to provide regulatory frameworks to facilitate the mitigation of its consequences on wellbeing. This is how the concept of Energy Poverty (EP) first appeared and specific legislation was passed at the EU level back in 2009 [3] and later became an important aspect of the EU’s ‘Clean Energy for All Europeans’ package [4]. Although there is an ongoing discussion on definitions and driving forces, with most conceptualizations insisting on the idea of energy inefficient housing and low incomes as key causes, it is widely agreed that “energy poverty can be seen as situation in which a household lacks a socially and materially necessitated level of energy services in the home” [5]. While energy poverty definitions refer to all domestic energy services and energy sources, electricity stands out as an essential household supply for a life with health and dignity.
