Abstract: This paper evaluated the spatial-temporal variation and coupling relationship between global primary energy consumption and economic growth from 1965 to 2020. Spatial autocorrelation analysis, coupling and coordination degree model, and the auto-regressive integrated moving average (ARIMA) model were applied. Also, we analyzed the regional inequality of global energy consumption with the Dagum Gini coefficient and decomposition method. The results presented diversity and heterogeneity of global energy consumption with impressive growth. Regional inequality has decreased or kept stable over time at a high level. The inter-regional disparity is the primary source of regional inequality in all energy consumption types. Under the multi-polar framework with weaker spatial clustering, the degree of global coupling coordination of FEC with economic growth has significantly improved, and a high level of coupling and coordination has been achieved since 2005. In contrast, except for China and the U.S., most countries exhibited a current and long-term uncoupling and imbalance between non-fossil energy consumption and GDP. According to the trend forecast, major energy consumers struggle to meet their prospective REC or NFEC targets without further action. The study highlights the urgency for coordinated strategies addressing regional heterogeneity in energy transition pathways while maintaining economic growth.
