That is how it works though. If my money is only allowed to be used to generate renewable energy, then it doesn't matter how the power that comes to my house was generated. Energy is energy. If everyone does what I do, then no one will be left to fund nonrenewable energy. But the only way that would happen is if the cost of nonrenewable energy went up proportional to the damage it causes via a carbon tax. And banning crypto mining is impossible. It's arbitrary math. You can't ban a computer from doing arbitrary math. At best you could discourage businesses taking crypto as payment, but even then people can operate 100% in crypto and avoid any regulations.
