We have "CAFE" in the US "corporate fuel economy average" for motor vehicles. Even with that we get into repeated trouble if the price of oil goes up suddenly. Most of peak demand electricity is produced from burning oil and natural gas.
It's a matter of national security and personal survival.
There are minimum standards for energy efficiency for many household appliances. Refrigeration, lighting, space heating and cooling, clothes washers and dryers. The power company can also MAKE you install power factor correction equipment if you are a large enough business and want to connect to the grid.
We share resources because the world is too crowded to do otherwise. The rich can always thumb their nose at the poor (like Al Gore living in a mansion and using a private jet), but the rest of us need to learn to share.
