For example, the per-capita CO₂ emissions in 2013 were of 20 tons/cap for the US, whereas it was 8.5 for China (world mean is 6.3): https://en.wikipedia.org/wiki/List_of_countries_by_greenhous...
Per capita numbers are rather misleading here. For example, Qatar has by far the highest CO2 emissions per person.
Climate change demands aggressive action all over the place. This is one component.
Also this is the literal opposite of virtue signalling. They passed a law. Virtue signalling is when you do nothing except express opinions.
1. Industrial-scale renewable generation would become more competitive and a larger fraction of grid power would come from solar/wind/hydro,
2. Prices could go up, and less electricity would be used,
3. It might become efficient for users to put rooftop solar on their houses. (If the initial capital outlay is a problem, that's what loans are for.)
This law, by comparison, is just a bad idea all around. It enforces one (pretty bad) solution in a nasty way.
Your statement, while true, did not refute his, FYI.
