Natural resource wealth in sub-Saharan Africa: A boon for public investment in renewable energy?

Abstract

This paper examines the role of natural resource wealth in financing public investment in renewable energy in 25 sub-Saharan African countries over the period 1996 to 2019. Results from two step system Generalized Method of Moments (GMM) estimates reveal that natural resource wealth negatively affects public investment in renewable energy. A distinction between the types of natural resources allowed to establish that this negative effect comes exclusively from the rents of point natural resources. Furthermore, the results show that institutional quality and human capital favor public investment in renewable energy. These results are robust when using the Driscoll-Kraay estimator. In terms of policy implications, it is imperative to promote good governance of natural resource rents, especially those from point source resources. It will also be necessary to redirect these rents towards the financing of structuring projects such as renewable energies in order to promote sustainable development.
