I mean, if I were mining, i'd lobe knowing my setup could run on sunshine or rivers instead of just burning through power. It's cool because it might even help grow clean energy which I'm all about.
It's hard to imagine that if you're living where the price of renewable energy is quite expensive tho. Not to mention the ROI from mining will take years to make the investment break even. I doubt the average miners care that much about contributing to renewable energy if their profit is not secured, to begin with. That being said, I believe it will be cheaper in the future. Not sure if it will change how much it will be used for mining though. CMIIW.
