Yes, the centralized nature of our energy grids are a problem. It’s both a blessing and a curse. It’s far easier to manage and makes investing in very expensive but very scalable energy generation systems feasible, but comes with the considerable downside that long distance power transmission includes all kinds of headaches and doesn’t respond well to large shifts in demand. A very distributed system, say with some sort of neighborhood level power distribution/sharing system and per-house solar or wind power and storage would remove the need for long distance power transmission, but would be massively more complicated to manage, and still wouldn’t solve all issues around large swings in demand, while introducing expensive ongoing maintenance (mostly in power storage). Ideally some kind of hybrid system where most power needs are met at the local level, with a few large systems to handle excess demand would probably be ideal, although then you’re double paying for maintenance as you have to maintain both the local system and the large centralized one, but in theory the load on both would be more manageable. Unfortunately the current system is very much NOT setup to allow for local power generation and distribution and overhauling it to support something like that would be non-trivial.
