The Moderating Role of Green Energy and Energy-Innovation in Environmental Kuznets: Insights from Quantile-Quantile Analysis

Abstract: The recent environmental challenges in Africa that emanated from global warming, human activity, limited access to electricity and overexploitation of natural resources have contributed to the growth of carbon dioxide (CO2) emissions in the region. This paper empirically investigates the moderating role of green energy consumption and energy innovation in the environmental Kuznets curve for the Sub-Saharan African (SSA) region using data spanning from 1980 to 2018. Our threshold model found that at least 54 percent of the population needs access to energy innovation before the region could be safe from environmental degradation. We conclude that investment in green energy, energy innovation and conservation of natural resources will help to mitigate environmental degradation in SSA in the long run. Policies should be targeted towards encouraging the consumption of green energy, and more investment in energy innovation beyond the estimated threshold will save the region from pollution and its implications.
