Despite sub-Saharan Africa's vast endowment of energy resources, more than half of the region's population remains without access to electricity, positioning energy poverty as a persistent constraint on sustainable socioeconomic development. Consequently, a growing body of empirical literature has examined the socioeconomic consequences of energy poverty; however, its spatial transmission mechanisms remain insufficiently explored. Therefore, this study investigates the spatial spillover effects of energy poverty on key socioeconomic outcomes, with particular emphasis on health, education, and labor market performance. The analysis employs three spatial panel regressions: the spatial Durbin model, the spatial autoregressive model, and the spatial error model, using data from 25 sub-Saharan African countries over the period 2000–2021. The results reveal that the spillover effects of energy poverty are more pronounced than the direct effects. The spatial Durbin model results indicate that the total effect of a one-unit reduction in urban energy poverty is associated with an increase of 0.17 units in life expectancy and a decrease of 0.79 units in infant mortality rates. Furthermore, energy poverty is found to be a significant impediment to educational attainment and labor market development. These findings underscore the importance of accounting for geographical proximity and the equitable distribution of energy infrastructure when designing policies aimed at alleviating energy poverty in sub-Saharan Africa.
