I think you're a bit too optimistic on solar deployment for residential areas. Sure, you're probably right in California, but Norway won't be powering their homes through roof-top panels.

Also, most people don't live in single family homes, they live in 30-100 family apartment blocs, where even at the equator there won't be enough roof space to power the whole building through solar.

Wind does have a massive land use problem as well (as does hydro). In most of the world outside the USA, there aren't huge swaths of unused land anywhere near residential or industrial areas.

Which is why for example France has green-lit 6 new fission reactors, and the EU in general is looking at declaring fission green energy to get the required subsidies. This is also why Germany, that went all in on wind and solar and even has a few days each year where the entire grid is running on wind+solar+hydro, still produces about twice the GHG as France (both total and per capita).
