During hot summer months, many utility companies promote the idea of using major appliances at night. These are things like your washing machine, dryer and dishwasher. The reasoning? The electrical grid is running at peak mode during the day due to the demands of air conditioning units. When you add the electricity usage of major appliances on top of that, it can lead to electrical blackouts. But doing household chores like washing clothes and dishes at night also comes with a savings. In addition to utility companies charging less for power at night, your home won’t be as impacted by the heat your appliances give off when in use. At night, the air is cooler and your home is, too, so you won’t feel the heat as much.
