Sub Saharan Africa (SSA) is a region of over 950 million people but also with greatest proportion of population without access to electricity. The World Development Indicators reveal that electricity-related CO2 emissions (CO2EM), and the ratio of electricity transmission and distribution losses (RETDL) have been rising in SSA over the past decades, implying deterioration in efficiency of the power sector. Given the recent rising focus on the Sustainable Development Goals (SDGs), studies on the impact of electricity consumption and CO2 emissions on economic growth remain vital to inspire energy policy and academic research. Several studies have examined environmental Kuznets curve (EKC) that hypothesizes environmental quality and economic growth nexus. Closely related to this study, plenty of literature is done on the cointegration between electricity, CO2 emissions and growth. Despite the fact, firstly, accounting for electricity quality is still lacking and remains a serious gap. Secondly, measuring both the nature and size of the influence of electricity-related CO2 emissions on the growth contribution of electricity stock (quantity) and quality is another angle that has not been properly interrogated in the literature. Therefore, we investigate the economic growth effects of both electricity stock and quality before and after accounting for electricity-related CO2 emissions.
