".. left to its own resources, – and the costs of energy implied – Africa should lag not lead in green energy. However, it is not in the global interest for Africa to be left to its own resources. If the capital inputs to energy generation and saving were available at world prices, the world could reduce emissions at much lower cost in Africa than in the North. Whether Africa leads or lags on greening thus depends upon whether international finance and regulation can rectify the region’s deficiencies in its own capital endowment."
Excellent article by Paul Collier on the opportunities and challenges for the greening of Africa's economy and energy system.
