South Africa’s economic growth is powered by fossil fuels. Electricity is produced mainly by environmentally unfriendly, coal-fired power plants. But some people are trying to change that. In the hamlet of Greyton, about 150 kilometers northeast of Cape Town, 100 activists have joined forces to make their town more sustainable and energy-independent, by turning it into a Transition Town. They want to revamp the entire local infrastructure, increase the use of solar power, and promote the use of regional products. They're also trying to educate local young people about the importance of protecting the environment. For more go to http://www.dw.de/program/global-3000/s-11487-9798
