And if you know anything about electrical wiring, do not look up how they do it in those plywood houses in US, any European building inspector would have a heart attack :)
We reserve 220 volt outlets and higher voltages (3 phase 480, etc) for the larger loads, and those plugs are huge, and not something found in a typical home.
2 times less voltage === 4 times more heating for the same resistance (heating is calculated from R times I^2).
This means that short circuits, wiring problems are potentially much dangerous.
