Did you know that 85% of the energy used for washing clothes and household linens comes from heating water? That’s right. Running the actual washing machine uses only 15% (or less) of the power necessary to launder your stuff.
Terrapass says that a switch of all U.S. washers to cold water would mean a savings of about 3o million tons of CO2 a year. That’s a lot of CO2.
Some detergents (powders) don’t work as well in cold water, so check into cold water detergent. Or just make sure to use a liquid.
CNET has a cool post on how detergents work, if you’re interested.
So, that laundry you’re going to muddle through today or this weekend, wash it in cold water rather than warm or hot – it’ll save energy and prolong the life of your clothes.
