They already do, at least in terms of second-order effects. You can't use the energy you buy to electrocute someone. You can't use that energy to power a meth lab.
That's not because the law specifically says you can't use electricity to do those things (it's about murder and illegal drug production and distribution), but the end result is the same.
Banning Bitcoin or Bitcoin mining need not be a specific energy-use law, even if that might be the purpose behind such a law.
