Abstract

ABSTRACT: Africa is growing rapidly both in terms of population size and economically. It is also becoming increasingly clear that fossil fuels impose a high price on society through local environmental pollution and Africa's particular vulnerability to climate change. At the same time, Africa has an excellent renewable energy potential and prices for renewable energy are reaching the price range of fossil fuels. Comparing results from state-of-the-art Integrated Assessment Models we find different options for achieving a sustainable energy supply in Africa. They have in common, however, that strong economic development is considered compatible with the 2°C climate target. Taking both challenges and appropriate solutions into account, some models find that a complete switch to renewable energy in electricity production is possible in the medium term. The continental analysis identifies important synergy effects, in particular the exchange of electricity between neighbouring countries. The optimal energy mix varies considerably between African countries, but there is sufficient renewable energy for each country. The intermittency and higher capital intensity of renewable energy are important challenges, but proven solutions are available for them. In addition, we analyse the political economy of a sustainable energy transition in Africa. Key policy insights An almost complete shift towards renewable energy (RE) is considered feasible and affordable in Africa. By 2050, electricity generation could be sourced largely from solar, wind and hydro power. Prices for RE in Africa are now within the price range of fossil fuels, partly due to the excellent RE potential. The optimal energy mix varies strongly between countries, but RE is sufficiently available everywhere. Addressing intermittency is possible, but requires investments and cooperation on the grid.
