Energy challenge in Africa |
|

The African continent will experience in the near future an unexpected growth in population and economy. In the meantime, it will have to deal with the effects of climate change, mainly caused by emissions from fossil fuel burning, by other countries outside Africa. This growth must be accompanied with an adequate growth in energy supply - mainly electricity – food production and potable water. If electricity production continues with the conventional fossil fuel burning as it does now, the future of the continent will be threatened by vast environmental and financial disadvantages slowing down the development. Renewable energies are the only feasible, economic and sustainable solution. The natural forces that can be converted to electricity are abundant in in Africa. However, they are of different potential, due to their source and geographic distribution. A wise mix of randomly fluctuating electricity production, like photovoltaic panels and wind, with controllable electricity production from hydro-power plants, geothermal energy and concentrating solar power, can ensure sustainable electricity supply. As these resources are not available everywhere in the continent, and are more than local demand in some areas, a cooperation between the countries is essential to transport clean electricity for long distance. In contrast to the European continent, where a very successful global electricity grid exists, a series of small nearly autonomous grids for Africa are recommended in this presentation. These grids are then connected together by means of high voltage direct current lines (HVDC) to bridge the long distances of the vast continent. Adopting the European solution will result in high losses of transmission. |
