Let's do personal wind and solar as well, it doesn't have to be the huge utilities doing it.
Widespread personal installations won't be sustainable in most situations. Instead, we should be working to create microgrids for higher resiliency and more efficient electricity transmission. While we're at it, geothermal heat pumps should be installed in a similar microgrid method for more efficient energy consumption
Why do you think that?
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: https://rubinmuseum.org/collection/artwork/wind-powered-prayer-wheel-20.406 , 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 mentioned that make a personal wind power as efficient as a giant turbine. I'm surrounded by Boeing people, I'll ask around.
