Grid or solar: looking for the best energy solution for the rural poor

South Asia has made tremendous progress in connecting rural areas to the electricity grid but the number of people in Africa without access has scarcely changed since 2010. More than a half-billion people in Africa don't have access to electricity, meaning the continent hosts 72% of the world's non-electrified population. The UN Sustainable Development Goals have set a universal goal of ensuring access to affordable, reliable, sustainable and modern energy for all by 2030. To achieve this, the continent will require a big electrification push.
