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. The website is hosted by the SAMSET project (see below). Information on energy in urban Africa tends to be sparse and dispersed. The information base needs to be significantly expanded, as well as made accessible through platforms such as the AfricanCityEnergy website.
