Energy-efficiency… for 2050
Energy-efficiency short-term targets have been discuss in a previous section.
Some governments have announced full phasing out by 2030 or 2050, depending of the dirty product type (e.g., gasoline car or natural gas water heater). They will only be credible after hitting their short-term intermediate targets.
Nevertheless, the focus may not be on rigid energy-efficiency regulations, because economists recommend carbon pricing punishments. The private sector can do it better (with carbon tax penalties) than bureaucratic regulations.
