Development of new standardized methods for calculating fuel poverty index: a study in the coast of Cabo Corrientes Jalisco

Fuel poverty poses a significant challenge to communities worldwide, particularly in vulnerable regions. Within this context, energy poverty is understood as the inability of households to access basic energy services, representing a barrier to sustainable development and social welfare. This article addresses the need for the development of standardized methodologies for measuring and analyzing energy poverty. In response to the absence of unified approaches for comparative analysis of energy poverty across different geographical contexts, this paper proposes a new methodology, based on data collected from coastal localities in the State of Jalisco. A principal component analysis was conducted, generating a normalized multivariate matrix, and through clustering analysis, similar criteria were grouped into different analytical categories. By applying this method, an adaptation of the Gini Index and Lorenz curves was achieved to precisely calculate an Energy Poverty Index, specifically in the coastal region of Cabo Corrientes, Jalisco.
