When community members participate in renewable energy planning and financing — especially with community microgrids or community solar — they facilitate the move to renewable energy, said the co-author of a new study on shared decision making from the International Institute of Applied Systems Analysis.

In the town of Freistadt, residents formed energy communities aimed at creating a microgrid managed by a private company. The residents could not opt out of the microgrid — which supplied all their energy needs — but they could choose among various forms of participation. They could install rooftop PV, take part in management or purchase a share of the project.
