It found many countries have wind and solar potential several times greater than their expected demand in 2030.

 

Instead of prioritising sites based on the lowest cost and best wind speeds, the report advises projects should be built closer to transmission infrastructure or to cities, slashing the risk and cost involved in installing huge lengths of power lines and also improving efficiency.

The report says the strategic siting of renewable power in this way could reduce the need for conventional generation capacity by 9.5%, resulting in cost savings of up to 20%, depending on the technology that was avoided.

Berkeley Lab Researcher Grace C. Wu said: “As a region, Africa is in an unparalleled energy crisis rife with electricity deficiency, lack of access and high costs.

“How African countries and the international community tackle this crisis in the coming decades will have large social, environmental and climate implications.”

The EU has announced a contribution of €300 million (£259m) for 19 renewable energy projects in Africa.
