Mameyes is a small community of about 1,000 people high in Puerto Rico's central mountains. But in its own way, it is one of the leaders of Puerto Rico's energy future.
Francisco Valentin grew up in Mameyes, where he runs a small store. Even before Maria he had big ambitions for his town. After Maria, he knew he wanted his community to run on solar power. And with the help of foundations, charities and the University of Puerto Rico — not the government — he has done that, converting the town's school, health clinic and several other buildings.
