I think renewable energy's decentralized nature is one of its most underappreciated features. You could never imagine a local community building a conventional electricity plant, they are centralized and that is the job of government.
I suspect the future will have much more local decentralized projects of this nature. When you can have robots running factories without the need for humans, why not self-finance and build these at the community level too? It's entirely feasible, and many people will want to do such things. It's initiatives like this that make me doubt the future will be dystopian.
