The theoretical peculiarities of energy poverty research: A systematic literature review

Energy poverty represents a substantial burden on development strategies for the developed and developing world alike, reducing the wellbeing of several million people and causing several hundred thousands excess deaths per year worldwide. It is also deeply interconnected with other problems in environmental and social development. Despite its global relevance and increased attention from governments, academia, and international institutions in the last two decades, the field lacks a clear theoretical foundation, specifically the absence of consistent and agreed-upon conceptual and measurement approaches. This research presents an extensive systematic literature review of energy poverty and related terms since the 1970s and up to the year 2020, focusing on theoretical and methodological contributions. The objective is to synthesize the most influential doctrines, trends, and insights about the phenomenon. The results show that conceptual diversity goes beyond the widely recognized dichotomy between the Global North and Global South, despite several attempts to move towards a composed theoretical framework. Moreover, they also show that measurement, rather than theoretical development, has been the field's primary focus, leading to many composite and single metrics. Due to the latter, the conceptual development has followed measurement advances instead of epistemological, semantic, or philosophical discussions, though this has started changing in recent years. Finally, the consideration of energy poverty as a broader phenomenon has fueled a profound debate on justice, which offers a more comprehensive understanding of the actual and expected position of energy poverty in society and development.

Automated summary

Energy poverty has significant implications for development strategies in both developed and developing countries, leading to reduced well-being and excess deaths. Despite increased attention in the past few decades, there is a lack of clear theoretical foundation and consistent conceptual and measurement approaches. The field has primarily focused on measurement rather than theoretical development, resulting in diverse and inconsistent metrics.
