Coal power plants, and most likely you receive your power from a coal supplied power plant... unless you're lucky enough to live in an area with alternative power generation, and of you do great for you. Bully for Bixby. Coal fired power plants can only operate at one level. Fully on.
During the night, this power from the burning of coal is not utilized. As the day starts, the load demand goes up and up into the peak hours of demand. In most areas, the demand goes up and beyond the straight unwavering level and ability for the plant to produce and provide. The power companies, then must switch on line more expensive and dirty power plants.
If we were able to shift a small amount of the demand off of peak demand times, we could utilize the wasted energy produced during the night hours. A small fraction of the population would be needed to change their sleep and work patterns. Move from traditional early morning start times to starting their days in the early afternoon.
I for one, would step up. To help save our resources...and sleep passed noon.
