Good laundry room habits, including some occasional minor maintenance, can save energy and shave nearly $300 off your annual utility bills. That’s because you can curb the biggest energy culprit: the cost of heating water.
The bulk of a washing machine’s operating costs—around 90%, says Energy Star—go to replacing the hot water in the home’s hot water tank. Reduce the amount of hot water the appliance uses, and you’ll significantly shrink its associated utility bills. By washing fewer loads and doing those loads in cooler water, you can save around $200 per year.
1. Use cold water. Switching from hot wash to cold, according Michael Bluejay, also known as Mr. Electricity, who specializes in electricity savings, can shave up to $215 per year off your electric bill. If you have a high-efficiency washer or gas-fueled water heater, assume savings of about half that figure. Cold washes are generally as effective in getting clothes clean as hot.
2. Only wash full loads. Discounting the energy required to heat the water, it costs around $60 per year in electricity to run the washer, according to the U.S. Department of Energy. Because it takes just as much electricity to wash a small load as it does a full one, you’ll save money by only washing full loads. By reducing the number of overall loads by one-quarter, you can save $15 a year.
