The people of Cameroon, Africa will soon learn how to construct their own wind turbines and hydroelectric plants using local materials in a pilot project organized by Munich, Germany-based Green Step. The organization will teach the 7,000-person town of M'muock how to build and operate small renewable energy plants out of wood and old car and radio parts.

"For the first time, people in the town will have access to affordable electricity." -- Cornelia Ehlers, co-founder of Green Step
