Not so. Most household appliances contain motors (excluding entertainment appliances). Motors (ac induction types; the most commonly used) are generally less efficient at lower voltages (largely by virtue of their increased I^2*R loss) and draw more current to perform the same amount of work or produce the same amount of torque. Thus, more load on the grid. Imagine all the air conditioners and fan motors laboring under a voltage depression this summer. California would be dark a lot quicker.
