The point anovikov was making is that AC is not intrinsically more efficient. In fact, it is less efficient over very long distances dues to radiative losses. We don't use AC because it lets us use more efficient voltages today. We use AC because 100 years ago we didn't have the technology to boost direct current to high voltages.

OK, so if we had been able to just blast DC down the lines at 100kV or whatever, that would have been better?
