I wasn't going to weigh in on this, but here goes. For residential and commercial non-industrial use, heating and air-conditioning must consume the most power. Since these are feedback controlled systems, lowering power consumption by reducing line voltage would only increase the amount of time the heater/ac system was "on." Am I missing something?
