I wonder if something like 'progressive' energy pricing might be a solution here. It's kind of a weird idea but effectively some baseline 'required for living' amount of energy is free and then scales some non-linear amount, e.g. exponentially but not really, as usage increases. So some grandma with her 3 bar electric heater is paying some token amount for her usage over what is deemed 'baseline' but then crypto miners or industry is effectively subsidising everyone and also incentivised to reduce usage more heavily.
