It makes grid planing an absolut nightmare. We need to overbuild by a lot so a few days with less wind and sun doesn’t lead to blackouts. Big windparks can be turned off reliably if there is too much energy produced, but the same can’t be said for personal installations.
While it’s possible to disconnect personal solar cells from the grid by increasing the frequency a bit, you can’t just do that if the village is still connected to the entire grid. You first have to switch the whole village manually into island mode. Not to mention that a lot of times they don’t restart automatically.

As I understand it, the efficiency of a wind turbine increases with blade size, so multiple smaller personal wind turbines are less efficient than fewer, larger turbines that serve a neighbourhood, as well as costing much more and using more overall resources.

I had a friend of a friend put up a mini turbine when it first started, it was mostly DIY. I’m pretty sure there could be some basic DIY ways in a form that isn’t blades, that are efficient enough and could be done with recycled materials. The batteries I guess would have to be new. Still a step in a great direction.
I’m thinking more along the lines of this: rubinmuseum.org/…/wind-powered-prayer-wheel-20.40… , but stacked with maybe 5 rows each depending on how much one could hold. You could add on as needed and have walls of them.
I’m sure there are local engineers that could come up with new ways other than what I mentions that make a personal wind power as efficient as a giant turbine. I’m surrounded by Boeing people, I’ll ask around.
