Why don't we Tax or tax more on,
Any lighting that isn't an LED Lightbulb?
Or how about trade tariffs?
Illegal Drugs? First make them legal, then tax the shit out of them!
Rich people, especially capital gains?
Corporation?
Non green sources of energy?
Bad food?
Religious Establishments? (Remove tax credits for charitable donations to churches, because they aren't charities!)
What else should we tax the hell out of?
