Please educate yourself: PoW cryptocurrency is a red queen's race that is deliberately inefficient. I can't think of any other technology that continuously and deliberately wastes more and more energy. The only analogy I can even think of might be a nuclear arms' race: you have to keep building more and more missiles or there's a risk your enemy might get the jump on you.

Any engineer worthy of the title should be appalled by this inept and abusive design.
