I have seen many responses that people hate the idea of using electricity wastefully because they want to cut down on the use of coal.
With a coal fired generation plant, they have to burn at a high rate 24/7 to keep the superheated steam moving to the generator unit turbines, whether people are actually pulling electricity of or not. The turbine generator has to maintain a constant speed. The regulators mere supply the line for what is pulling across the transmission line, to maintain 60 hertz power.
