We could just try to subsidize carbon neutral energy and establish a carbon tax. People could consume more carbon neutral energy than they're consuming carbon-based energy right now. This is one of those "we've done literally nothing and we're all out of ideas" problems because we refuse to put a finger on the scale and tip the balance economically towards carbon-neutral energy. The ghost of Adam Smith will apparently punish us in the afterlife if we ever think of doing that.
