Abstract: The case study of the renewable energy workshop of the 'Nea Guinea' non-profit organization in Athens, Greece, is presented an example of how communities can practice paths towards degrowth though open source renewable energy technologies, convivial and experimental ways of learning and thus providing more resilient futures for the social networks in which they participate. The main themes discussed are the ideas of open knowledge commons, community-driven design with internet collaboration and open design approaches for local manufacturing, while the concepts of resilience and self-reliance are introduced for emerging rural communities in degrowth.
