Household laundering takes a lot of energy—not even counting what’s required to haul the loads up and down stairs. In the U.S. and Canada, most of that energy is used to heat up water because laundry detergents have been designed to work with warm water. But earlier this year, Procter & Gamble (P&G) launched Tide Coldwater, a version of the popular laundry detergent designed for good cleaning in cold water. Why? Because consumers want to save on energy. Home laundering accounts for up to 36% of total household hot water use, according to a study by P&G and Exponent, a consulting firm. P&G claims U.S. consumers can save up to $63 per year in energy costs by washing in cold water. Their calculation is based on national average electricity costs, a water heater set at 140°F, 7 loads of laundry per week, and conversion from warm to cold water.
