Exploring energy security in China: our distance to energy justice

Energy justice serves as a pivotal factor in the global shift towards energy transition. A comprehensive evaluation of energy security necessitates the integration of energy justice principles. Accordingly, this study introduces an energy security index (ESI) from the perspective of energy justice and assesses the energy security of 30 provinces in mainland China. The analysis, covering data from 2001 to 2020, explores the spatiotemporal variations of ESI across these provinces. It also examines their spatial relationships and clustering tendencies using Moran ' s I analysis. The findings indicate that, when viewed through the lens of energy justice, the majority of provinces display a low ESI, characterized by modest enhancements and persistent low -value conditions from 2001 to 2020. This trend primarily results from the inadequate emphasis on justice components in China ' s energy transition and the continuous failure to significantly boost regional energy supply capabilities. Additionally, this study highlights significant spatial disparities and positive correlations in ESI values across provinces. Regions abundant in resources tend to register higher ESI values, whereas resource -scarce but economically advanced areas show lower values. These insights are crucial for the formulation and adaptation of differentiated energy strategies, especially those focused on achieving energy justice and fostering a balance between regional energy supply and demand.
