A lesson with resources to explore issues for the 1.6 billion people who do not have access to mains electricity. The lesson explores what it is like to live in Africa without light and introduces the idea of solar energy as a simple solution. The resource begins by linking to a video about John and his family who currently use kerosene lamps in their home at night. It explains how similar lamps have caused fires in homes and schools nearby and how the black, sooty smoke they produce causes serious health issues. Pupils then go on to explore where in the world there is little electricity and how solar energy can offer a safe and affordable alternative.
