Who: Written by David Moinina Sengeh concerns Sub-Saharan African community When January 15th 2015 Where Sub-Saharan Africa What Since nearly 70% of sub-Saharan Africa lacks access to stable electricity, it has become imperative to find a way to substitute the faulty yet very expensive appliances commonly used (Diesel-powered generators, etc). However, the problem is that installing a complete electricity infrastructure would be too expensive and take too long, making it counterproductive. A possible solution that Sengeh argues is that the increasing use of Microgrids, small, local versions of electricity grids, could strongly help give the population access to reliable, inexpensive electricity, costing about ¼ of the price for Diesel. Why This site shows the economic troubles the population of Sub-Saharan Africa face in terms of lack of access to electricity. However, it also demonstrates the strong efforts they are making in trying to make it more reliable, attainable, and less expensive. Further efforts also lend themselves to investing in renewable energy to provide these types of microgrids for communities not located near major towns. |

FOR THE WORLD’S 1.2 billion poorest people, who are facing a long and perhaps endless wait for a connection to mains electricity, solar power could be the answer to their prayers. A further 2.5 billion are “underelectrified”, in development parlance: although connected to the grid, they can get only unreliable, scanty power. That blights lives too. The whole of sub-Saharan Africa, with a population of 910m, consumes only 145 terawatt hours of electricity a year—less than the 4.8m people who live in the state of Alabama. That is the pitiful equivalent of one incandescent light bulb per person for three hours a day.
