This African City Energy website is a resource to help those involved in sustainable energy challenges in urban areas of Sub-Saharan Africa to find relevant information. Given fast urbanization rates, the future of energy in the sub-region is significantly urban, demanding at least a partial shift in emphasis from rural areas to our cities and towns. The documents and information on this site will hopefully provide a useful collection for development organisations, municipalities, researchers, NGOs and national governments engaging in this important field.
