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
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.
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.
They’re just isn’t enough roof area/roof space per person in dense urban settings. Not by a long shot.
Nice parks are one of the amenities that can be put in a "15 minute city"; the nicest city I've ever lived in, Brisbane (in Queensland, Australia), had beautiful large parks within easy access of the downtown areas.
By contrast, currently I live in a suburb, but it doesn't really give me a nature fix when I need it so I have to go to elsewhere anyway.
If that is what you are worried about, then isn't the easy solution to build thicker walls?
You paranoid idiots can shut the fuck up about 15 minutes cities.
Only the truly gullible are afraid of OTHER PEOPLE having shops within walking distance.
