Solar energy gains momentum in the Sahel

Significance There are large regional variations in access to electricity, ranging from less than 10% electrification in Chad to a high of 70% in Senegal. Most countries are heavily reliant on thermal and hydro power; solar energy would allow them to utilise the region's many months of sun to increase their electricity output with minimal environmental impact. Impacts Despite the region’s dry climate and highly seasonal concentration of rainfall, hydropower will play an expanding role. Gas will provide a less carbon-intensive generating option for Mauritania and Senegal, but is less available to other Sahel countries. Local solar and wind installations could be key in supplying the numerous scattered rural communities and towns.
