"proof of work" blockchain-based crypto-currencies deliberately waste power and continually increase this wastefulness by design over time. bitcoin proof-of-work complexity increased 4x in 2018 alone. no amount of renewables CAN cover this, nor should they, as it's bad design and should be phased-out for something else. invent that "something else" and you will have done something useful.
