We've covered this a lot in the community, but the short version is:

a) The goal must be massive increases in clean energy production (eg via nuclear or other renewables), as opposed to reduction in consumption (which quickly hits diminishing returns and runs into the fact that Asia isn't going to freeze its economies). See the Henry Adams Curve: https://twitter.com/balajis/status/1327009794343931905

b) Proof-of-work mining in particular is a way to turn curtailed/stranded energy into cryptocurrency, rather than simply wasting it, which can be used to make renewable energy more cost-effective.
