Energy poverty has become a critical problem that demands innovative approaches to studying and solving it. This study consists of a systematic review of the nexus approach applied to energy poverty in scientific publications in the 2000–2025 period to examine the interrelationships among the economic, social, technological, and environmental dimensions that perpetuate energy poverty. The findings show that 44 % of the studies emphasize the economic dimension, exploring how the cost of energy affects household income, while 20 % address technological innovations such as energy efficiency and renewable energy. The social and environmental dimensions, accounting for 19 % and 17 % respectively, highlight the importance of gender equity and the impact of climate change. An analysis of geographic scales reveals that studies in Asia and Europe predominate, while Africa and Latin America are underrepresented. Methodologies such as surveys, index creation, and modeling have proven to be key tools for addressing the complexity of the phenomenon. There is a need for inclusive policies and sustainable technologies that integrate gender equity, environmental sustainability, and adaptability to local settings, promoting fair and effective energy transitions.
