I think people underrate how much square footage it is going to take to modernize a grid.
In a southern enough location, a big enough house might be able to generate enough power for itself for a few months out of the year if it doesnt have an electric car to charge.
But take every high rise, office, vehicle, manufacturing facility, etc in a city and single digit percentage seems pretty good.
Agree with this, but also want to mention something not clear in my post, that we are US focused right now, the energy mix is going to vary alot by geography. The UK does not have the land for lots of large scale solar, so their mix is going to be mostly wind, nuclear and rooftop solar might be a higher % as its a more urbanized country compared to the US. But it is unlikely it will be +10% even there.
