Well China is no longer allowing energy plants to sell power to miners which is probably a majority portion of the problem you are referring to.
It may turn out that there are other regulations (e.g. privacy regulations) preventing a company from gathering that information about individuals, though. At which point the power company would probably have to stop selling to individuals altogether (i.e. provide no residential power service any more, just private commercial/industrial service to other companies, because companies have a lot fewer privacy protections so it's easy enough to figure out whether they're mining.)
