During the lovely summers I spent in Bavaria, I learned that the reason their power lines go from house to house or underground - it is the short distance. Figure the amt of miles in California to string lines!!!! So we cannot blame the power company (though I would love that) for the problem. That is also why we have 120 instead of 220.
Short distance has nothing to do with the 120/220 difference. As a matter of fact, higher voltage is more efficient for transmitting electricity over long distances, and transmission lines use hundreds of thousands of volts.
The reason US uses lower voltage is that early light bulbs burned out too fast at higher voltages. The rest of the world got their household electricity installed a bit later, when this was not an issue any more, and so could adopt a somewhat more efficient voltage.
