The Department of Energy estimates that up to 90 percent of the cost of laundry comes from the energy used to run your hot water heater! Conserve water (and save some money) by switching the water temperature to “cold” when you do laundry.
Wash your laundry on “cold” cycles. Just like that, you’ve taken a big chunk out of your home’s energy usage! Plus, your clothes will still get just as clean – advances in technology and detergents have made cold-water washing just as effective as hot-water cycles!
Use a normal amount of detergent. Contrary to what you may have heard, you don’t need more detergent just because you’re washing your clothes on the cold cycle.
Know when to use hot water. If you’re trying to disinfect and clean, opt for a hot-water cycle. We recommend choosing hot when you’re washing things like dish and bath towels, which tend to carry more bacteria than other types of laundry.
