Sustainable energy could regenerate Africa’s Sahelian zone by using the region’s abundant clean energy potential to transform lives, diversify economies, give hope, and protect the planet. Analyzing viable pathways to move the Sahel away from energy dependency to energy agency that delivers accessible, reliable, and affordable energy for all, is the focus of this Human Development Report, which covers Burkina Faso, Cameroon, Chad, The Gambia, Guinea, Mali, Mauritania, Niger, Nigeria, and Senegal. The HDR uses empirical techniques and political economy analyses to consider optimal energy strategies that would be most appropriate for the sub-region and also for each country’s context.
