The target for many countries around the world is to reach net zero emissions within the next few decades. That means a dramatic move away from fossil fuels like oil, coal and gas. For some the answer to the problem is to boost “green” electricity production, so that we can run our transport, our homes and our industry on electrical power. We already have a lot of the technology to produce clean electricity. But for hundreds of millions of people around the world, especially in sub-saharan Africa, the real problem is the lack of access to electricity.
