There was an article posted somewhere on Lemmy a few months back where someone tried to do similar calculations for the US as a whole. What I took from the result was 95% renewable was achievable and still cheaper than fossil fuels. However the over provisioning of renewables and over double the storage needed to reliably achievable 100% made that infeasible with today’s proving and technology. Basically you can install storage to cover when the sun is not shining but it’s much more difficult to cover weeks of gloominess
Solar isn’t the only renewable choice, though. It’s just the easiest to do on an individual level. Also, there are plenty of areas for which weeks of gloominess will never (on human timescales) be an issue.
