What bitcoins are good for is funneling money from people who have money and no better ideas what to do with it or incentives to do anything with it, towards people who want to build renewables even though, their output at times already has a negative price in absence of bitcoin mining. Sure, in totalitarian economy there could be a lot of smarter ways to utilize resources and opportunities, but we don't have such economy for very good reasons, so in our economy, bitcoins are the simplest possible mechanism (technologically, politically and economically) that facilitates this funneling and we are lucky it already exists. The only problem is the cost of new mining hardware, but with Moore's law dying out and fabs overbuilt because of the pandemic shortages I think new, more efficient generations of mining hardware should come out at longer intervals and mining with few years old hardware should be feasible if you are powering it with renewables at peak production times.
