Decoupling energy consumption from economic growth in Africa: the role of sectoral energy efficiency and economic structural change
摘要
This study examines how sectoral energy efficiency and structural economic transformation contribute to reducing energy consumption using decomposition and panel regression methods based on data from 22 African countries between 1990 and 2017. The results reveal that improvements in sectoral energy efficiency and changes in economic structure led to reductions in energy demand by 22% and 18%, respectively, offsetting a projected 20% increase in final energy consumption across the agriculture, industry, and services sectors. Regression analysis further confirms that economic growth is a major driver of total energy consumption and its components—activity scale, efficiency, and structural composition. Additionally, imports were associated with reduced domestic energy use, while exports were linked to increased energy intensity. Other influential factors include urbanization, energy prices, electricity access, renewable energy uptake, and foreign direct investment, with their impacts varying by geography, income group, and oil production status.
