A new way to solve the power demand "Africa does not lack energy, but energy is not used rationally." Cheikh Anta Diop, an African historian and politician, said so about Africa as early as 1985. Now, 30 years later, modern, reliable and clean energy has become a key factor in supporting Africas development. The energy supply situation in Africa has not been good for a long time. According to a report issued by the United Nations Environment Programme, the power supply situation in many African countries is very poor. A large number of people, especially rural people, are without electricity. In rural areas south of the Sahara, only 2% to 5% of households can be connected to the power grid. This has seriously restricted the overall development of the African economy. In March this year, at the 15th High-level Conference of African Ministers of Environment, Achim Steiner, Under-Secretary-General of the United Nations and Executive Director of the United Nations Environment Programme, said that the development of renewable energy would help solve the long-standing problem of power supply in Africa, thus providing opportunities for leapfrog development in Africa. The entire African continent also sees this development opportunity, and various countries are betting on renewable energy power. South Africa has taken the lead, proposing to invest $90 billion in the development of renewable energy in the next 20 years, and plans to increase the total use of renewable energy by 40% and double the countrys total power generation. According to Radio France Internationale, South Africa not only plans to build solar farms with a total installed capacity of 5000 megawatts, but also plans to vigorously promote the construction of a series of renewable energy power generation projects such as wind energy and biomass energy. South Africa was followed by a group of North African countries, among which Morocco was the most active. It is understood that as early as around 2000, Morocco built the first wind farms in its eastern city of Tétouan (T Tétouan). Since then, two more wind farms have been built on the countrys Atlantic coast. In addition, Morocco has planned a series of solar power plants in eastern cities, hoping to increase solar power generation to 2000 MW by 2020, accounting for about 18% of Moroccos total power generation. Algeria has also launched a sustainable energy development plan, investing 300 million euros to build solar panel factories in cooperation with German enterprises. West African countries are actively developing their abundant hydropower, solar and wind resources, hoping to meet 10% to 20% of their electricity needs in the future. Kenya and Rwanda in East Africa are bullish on wind power and biomass power. Data show that Kenyas wind power generation has ranked first in the world; Rwanda has built a number of biomass power stations, using biological raw materials such as bagasse to generate electricity; Tanzania and Mozambique are also planning wind and solar power generation projects.
