her non-profit organization, ibeka, specializes in micro- hydropower plants that benefit villages, because there's plenty of water in indonesia. >> we only borrow the water to be diverted, just to use the energy of the water without taking the material of the water. so, it is still good for our ecosystem and our habitat. because after we use the water we put back the water in the same stream of the river. >> puni and iskandar divert only a little of all the water that comes from the mountains. the canal is 400 meters long. that makes the difference in elevation large enough to generate power. transmitted to the turbines, it supplies the entire village with electricity. >> it is not complicated, technically. but for me, it is much more complicated socially. because then it has to be run and operated by the community -- how to empower them to understand about this system and give them the responsibility to operate and maintain it. >> iskandar, an engineer, trains the villagers. now they run a three-shift system to supervise the plant. it generates about 3700 euros in revenue a month. puni ha
