> at the moment, every dollar spent on fusion is a dollar not spent on building more solar panels and wind turbines You are of course technically correct ("the best way to be correct"), but let's be honest: figuring out the optimal allocation of resources between solar/wind/geothermal and fusion research is unsolved problem. It's probably outright unsolvable. It's also not a problem of one or the other. We will need both. Remember that fusion research is not just about fusion. The materials technology advances are almost certainly going to show up elsewhere in various forms. To top it off, the nature of the technology itself requires that a non-trivial fraction of the funds are directed towards fundamental research. We can not know, or even guesstimate where those results end up being used outside of fusion research tracks. I will not be surprised at all if/when some research done for advancing fusion will be used to improve solar and wind technologies.
