Would the US save electricity with a standard house current of 220v ?

No, using Ohm's Law, you will find that voltage and amperage is inversly proportionate, but wattage of a load remains constant.

Utility bills are based on wattage and time.

I realize that, I was referring to line loss being less with 220v and over the whole US it must add up.

Line loss is minimal and taken care of using conductors large enough to reduce and eliminate voltage drop.

Besides, a bit too late to change everything over now, don't you think?

Don't give Barry anymore ideas on how to "fundamentally change America".

I think he has done enough damage.

You do realize that the power company is not running 120 every where. Voltage is much higher and steps down locally to give you 120 or 240. This is not going to change, last change was back when we went from 110 to 120, I think in the 50's. Edison and Tesla had this argument long ago.

I could not agree more!

The real savings will come from the replacement of incandescent lamps with cfl or led lamps and the replacement of low efficiency a/c and heating units. These two uses of energy are the bulk of use in the USA. These could cut use in half in the best case. Also refrigerators. A new one uses about half the power of one 12 years old.
