... voters (or however we want to handwave preference aggregation) are very passive about carbon-free energy (and global warming and sustainability and economics and ...)

they either pick some pet peeves (coral reefs, rainforests, global South inequality, desertification) and usually start buying things (EVs, PV panels, heat pumps)

but when it comes to policy they usually revert to Greenpeace/degrowth/NIMBY cult members
