Land issues? Seriously?
The land issue for solar is a non-issue, it's like fake hand-wringing by the oil astroturfers over birds and windmills when skyscrapers kill 100xs more birds. There's this type of land called desert. Also, there is this thing called roofs where modern solar panels only need a small part of the roof to do a suburban house or apartment building including recharging your EV.
The land issue for wind is even less on an issue:
As for wind, I don't know if you've seen windmills on farms but... yeah, the pole doesn't take up much space. Then there is offshore wind. Windmills can integrate with existing use land (why not nature preserves?), you don't need to dedicate acreage to windmill farms.
Meanwhile, fusion reactors have a wee bit of problems with neutrons flying everywhere and turning the reactor vessels slightly radioactive from neutron capture. Maybe they'll fix that with good absorption spectrum elements, but let's not pretend fusion is 100% clean.

But again, the promise is there for fusion and LFTR/"new" fission. Keep the research, maybe the economics will turn around. Industry sure would need it to fully decarbonize, or, heck, space colonies. Or flying cars! Or any of the other sci-fi stuff we have given up on.
Right now we have an existential threat from GW, and an actual industrialized / productized and economic path is right there: wind and solar. That's what we need money printing for.
