The issue with your argument is there's no real evidence that Bitcoin mining is spurring investment in renewable power plants, and quite a bit of evidence that it is deterring disinvestment in dirty power plants. Furthermore, the links you point to start out by talking about how Bitcoin miners are being paid to not mine.

It's actually rather more like "we'll rapaciously use energy to bring the grid to its utmost limits, but don't worry, if you pay us lots of money [in some cases, more than we get from our regular business!], we'll happily not use quite enough to actually cause it to buckle and fail." Sounds like an extortion racket, doesn't it?
