East Africa has several fast-growing economies that will see a sustained increase in energy demand over time. In this working paper, Ndung’u and Azomahou describe the extensive costs of climate change already borne across the region, hurting economic growth, food security, health, and human capital. Since agriculture is the key source of livelihood and employment for much of the region’s population, the authors draw particular attention to the urgency of adaptation and resilience efforts in the farm section. To increase the energy supply and demand efficiently, East African countries can tap into their huge potential for renewable energy, creating regional grid integrations, with a modern regulator mixing in the multiple renewable sources in the region in an efficient way. This will not be politically simple—regional and domestic policy coordination will also require considerable cross-border sharing of technological expertise and increased foreign investment in clean energy deployment.
