This PhD investigates the potential of migrant remittances to drive renewable energy transitions in rapidly urbanizing African cities. As urban populations densify, energy demand increases, straining existing infrastructure and intensifying fossil fuel reliance. Data gaps and limited exploration of the contribution of remittance flows hinders comprehensive planning. This project addresses these gaps by examining how remittances—typically studied indirectly in terms of increased fossil fuel use—might also support investments in clean energy technologies, thereby enhancing urban sustainability.
