Since 2007 the Siemens Foundation in cooperation with the Global Nature Fund has been involved in a project to replace kerosene lamps, commonly used for night fishing at Lake Victoria in Africa, with solar-powered LED lamps. Today, the Kenyan part of Lake Victoria is almost free of kerosene-operated lamps – a huge success! However, fishermen still use old and unreliable gasoline engines to power their boats emitting more than 400,000 tons of CO2 on the world’s 3rd biggest lake every year. Gasoline and oil spills have a devastating effect on the drinking water and the environment. Time for a change!
