In 2013 President Obama launched the Power Africa initiative, to try to double access to electricity across sub-Saharan Africa using renewable sources.
The target is to add 30,000 megawatts by 2030. The project has only generated 2,000 megawatts so far, but energy businesses operating in Africa say the programme has boosted investor confidence.
Its future under a new administration is in some doubt.
In an apparent reference to the project, incoming President Trump tweeted his disapproval, saying: "Every penny of the $7 billion going to Africa as per Obama will be stolen — corruption is rampant!"

True!
