Let people who care about the environment pay extra for their electricity. You do not have the moral high ground if you force people to pay extra for electricity through coercion.
Your arguments seem to be straight from the conservative playbook. No doubt then you would also object to people getting handouts from the govt. A situation where a person gets cheap electricity and allows someone else to pay for it sounds exactly like a handout.
Poisoning people is, in general, a great deal less moral than charging them more money.
It is also not dirty. We're not talking about particles of carbon in the air, we're talking about CO2, an odorless, invisible gas.
