Access to electricity correlates well with urbanisation. So the solution is not to build out a dense grid, which would be very expensive, but to install thousands of solar-powered micro-grids, one for each village. Electricity is essential for economic growth, and without it the developing countries of Africa will struggle to grow. Maybe one of the best things billionaires could do is to help eliminate poverty is to contribute to funding micro-grids across Africa.
Apart from the Congo basin, Africa has good (in some cases, superb) wind resources. Adding small wind turbines to solar micro-grids will limit the storage needed. It's doable.
