What’s interesting about this is the shift in power generation from big facilities, to smaller, private facilities.
Electric power generation has always been a large cooperative endeavor. Generation took huge machines, that were very expensive, so whether public, or private, they were big operations. Hoover dam, the TVA, public utilities, etc.
But with solar, power is now scalable - you can make as much or as little as you want, in a way that doesn’t change the cost/unit of generating capacity very much. Scale up or down as needed. Storage is a separate issue, but similarly scalable.
So, it’s possible to go “off grid” into smaller communities with shared resources, or even private dwellings with sufficient resources for generation and storage.
This wasn’t possible in the past because the cost of generating capacity was so very high, and there was a threshold for affordable power that required a very large plant.
But that has changed, and the possibilities are interesting.
