And even this is, on its face, a ridiculous end goal: we should be building renewable sources of power to replace our societies’ needs, not to supplant them with cryptocurrency.
(It also undermines the original point of the article: what incentive do bitcoin miners have to make renewables more available, if they can just pack up their rigs and move to wherever energy is cheapest? Mining incentivizes short-span access, not the kind of massive distribution grids that we actually need to make renewable energy sustainable and reliable.)
What's valuable is purely subjective. That's what makes markets work. Its also why planning economies from the top down doesn't work. What seems like wasted energy or capital to you is very useful to another person. Many people (myself included) believe that a decentralized, digital, hard money that is tied to the real world through energy is extremely important. So to those people its not a waste of energy, far from it.
Here is my opinion: it is entirely possible, common even, for people to be just plain wrong about the things that they value. That doesn't mean they don't value them; it means that their underlying justification is predicated on transient conditions (like artificial scarcity) or is otherwise underdeveloped w/r/t to their motivations. Bitcoin epitomizes this.
