Are you saying 220 volts is better? It doesn't require as much copper, I suppose. Then the issue is, should we use split phase, single phase, 2 phase power. Then there is the frequency 50 hz or 60 hz. Changing to 50 hz would be problematic because many devices use the line frequency to lock the speed of rotating shafts.
