The future energy lab in Berlin proposes valuable advice and guidlines for the „prosumer“ revolution in energy technology. From the own or home production of energy, the sharing of investments and infrastructure to the distribution network and finally consumption, the whole life cycle of energy is treated with a concern for environmental and financial sustainability Sharing is the way forward and many solutions build on this basic idea to move beyond the individualistic approach and fossil fuels cheap in the short term, but more expensive to society in the medium to long term. As most solutions make use of digital tools the issue of cyber security has to be a concern right from the beginning or even the planning phase. Joint production and consumption rely on people and communities reaching compromises. However, wholesale resourcing and averaging over households allows cost savings. The technology is available already, the skilled people to implement these solutions are currently the bottleneck. DIY will have to bridge the gap as neighbors learn from neighbors as yet another form of community building and engagement. (Image gamification of community decision making, SCCON Berlin 2024)
