The numbers today in the developed works don't back it up. It's Jevons Paradox btw, the person that came up with it was called Jevons, not Jevon.

The US has a lot of wiggle room because it uses almost 2x electricity per capita than e.g. Germany. People don't need electricity, they need light and cooling. If you do the math, that is hundreds of GW of free "new" capacity just by getting the same value for less energy. Obviously you can't do 1/1 comparisons, a lot of people in the US use AC whereas they don't in Europe. But overall the US could get more efficient in energy use. People buy new appliances all the time, make them be more energy efficient. Or don't and let the market sort it out. "The solution to high prices are high prices".
