CHUMBI, Kenya - Evans Wadongo is not yet 25 but has already changed the lives of tens of thousands of his fellow Kenyans living in poor rural communities by supplying them with solar lamps.

As a child growing up in west Kenya, Wadongo struggled to do his homework by kerosene lamp. He was caned at school if his family ran out of fuel for the lamp, and he permanently damaged his eyesight by sitting over the smoky fumes when they did have kerosene.
