Alberta's electrical demand varies throughout the day and across the seasons. When individuals are fixing supper and using home appliances, demand for power goes up, as it does during heat waves and cold snaps. It tapers off during spring and fall. Like other mechanical devices, generators fail from time to time. If they are wind-powered, their output varies with the wind.
Greg works at a power facility in Alberta. He has been charged with regulating generators. His task is to turn on generators in times of high power demand, and to turn off generators at times of low power demand. He tries to remain as efficient as possible. Recently, the area has experienced record cold temperatures on Monday and Tuesday. By the weekend however, the temperature returned to normal, and Friday and Saturday the temperature was very moderate and spring like.
Would Greg have turned on more or less generators on Monday than Saturday?
