Electric vehicles are still relatively expensive but a trial to help them power the national grid in times of need could see owners being paid. That could make them a lot more attractive.
Here's how spinning metal can smooth out the spikes in renewable electricity generation.
There has been no progress in expanding national electricity grids in most African countries since 2016.
Due to inefficiencies in global energy systems, energy falls short of even making it to the consumer, often lost in the form of waste heat.
