摘要：The aftermath of the 1970 oil price shock coupled with rapid urbanization, rising population growth,industrialization and increased environmental degradation in Sub-Saharan Africa (SSA) have necessitated aparadigm shift of emphasis from energy consumption to a thorough investigation into energy intensity. In spite ofthis, the evidence for SSA is sparse as both theoretical and empirical literature has not adequately interrogated theeffects of urbanization, industrialization and economic growth on energy intensity. Using panel data from 1980 to2015 covering 36 SSA countries, this study finds answers to this question under the standard Environmental KuznetCurve (EKC) framework. The system Generalized Method of Moment (GMM) estimation revealed that, in the longrun, both urbanization and industrialization tend to increase energy intensity in the 36 selected SSA countries whilethe contrary is established for FDI and trade openness. Inflation was also found to be associated with rises in energyintensity in SSA. Additionally, our finding confirms the existence of a valid EKC hypothesis for energy intensity; theexistence of an inverted U-shaped relationship between economic growth and energy intensity in SSA. Finally, it isobserved that the SADC zone of the region, in particular, is exhibiting rising energy intensity as compared to theECOWAS sub-region.We discuss some policy options that could potentially improve energy efficiency in the subregion.
