 Thus, for designing auctions for purchasing power, for establishing feed-in tariffs, or other instruments promoting RE, the energy sector regulator has a significant impact on the penetration of RE in Africa and other regions.Several large-scale solar power facilities are under development in Africa including projects in South Africa and Algeria.Although solar power technology has the potential to supply energy to large numbers of people, and has been used to generate power on a large scale in developed nations, its greatest potential in Africa may be to provide power on a smaller scale and to use this energy to help with day-to-day needs such as small-scale electrification, desalination, water pumping, and water purification.
