ARED has developed a solar-powered, mobile phone charging kiosk that can be towed behind a bicycle, a major mode of transportation in Rwanda. ARED is meeting a tremendous need: access to electricity to charge cell phones. The solution is clean energy, grass roots entrepreneurs, and mobility. The problem is that while around 40% of households have cell phones but are without access to electricity. In Rwanda, as in most of sub-Saharan Africa, cell phones have become ubiquitous and essential.
