Abstract Energy poverty presents a pressing challenge in the European Union (EU), worsened by recent geopolitical events and economic vulnerabilities, particularly highlighted by the COVID-19 crisis. This article explores the complexity of energy poverty within the EU context, emphasizing the necessity to define, measure, and monitor it comprehensively. It reviews the evolution of energy poverty definitions and causes, underlining the multifaceted nature of the issue influenced by factors such as low-income, high-energy prices, and building inefficiencies. Various measurement indexes are examined, and categorized into consensus, expenditure-income comparison, and direct/indirect measurement indicators, offering insights into their advantages and limitations. Furthermore, the work discusses mapping methodologies to pinpoint instances of energy poverty spatially. It also examines best regulatory practices employed by nations, including economic accessibility enhancements and structural interventions like investments in energy efficiency and renewable sources. Finally, the authors propose a novel approach to map energy poverty at municipal granularity in Italy, integrating economic vulnerability and building energy efficiency indices.
