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.
Tony is in charge of a power station in Alberta. He has been tasked with turning on and off generators depending on the demand for power. He has been ordered to try and be efficient as possible, turning off generators in low demand times, and turning them on in high demand times to satisfy needs. On Monday and Tuesday, Alberta saw record high temperatures, and on Thursday and Friday,  things cooled off for a more moderate and comfortable temperature.
Would Tony have been using more or less generators on Friday than Monday?
