Lots of people do today. Solar is profitable without subsidies.
Except transporting it over the grid usually doesn't make sense, and is neither easy nor simple nor cheap. So solar only really makes sense if you have a use for it nearby or even onsite. So for companies/factories/datacenters/... absolutely. To keep cities powered? Less so.
Yep. Traditionalists hate renewables and facts. Here in Texas, there's been an absolute boom in solar post snowpocalypse. I'd gladly vote for shifting corn and soy subsidies to renewables, especially as grants for 1-300 MW solar/wind facilities for municipal co-operatives. And for solid state and sodium municipal and infrastructure energy backup and v2g.
And, I think we should heavily tax data centers federally because they're electricity, water, and land extractive and sound pollution vampires hostile to communities they invade (often to the chagrin of locals because of NDA backroom deals with corrupt politicians).. they're tantamount to giant petrochem facilities in "sacrifice zones". The rich people can cry about leaving, as did FDR's friends did, but it's always an empty threat.
