To reduce CO2 generation would turning off night time advertising lights be acceptable?

All night/every night advertising signs and other excessive lighting burns up massive amounts of fossil fuels....mostly coal and natural gas. Satellite photos of the US at night shows huge amounts electricity used for no particular reason. If the federal government, as a part of the Clean Air Act ordered a reduction of non-essential lighting from midnight to morning would either party get behind this idea and would the coal and gas lobbies and companies that sell electric power allow such a directive to stand? I suspect they wouldn't, and I also suspect that the right wing radio 'entertainers' would go nuts over this idea for no other reason that it's 'the government'. But simply as a way to reduce air pollution and CO2 generation from coal and natural gas plants, wadda' 'ya think?
