I now select cold or tap water for the laundry because it uses 90% less energy than hot water. I like to think of it this way- if I paid $10 a month for hot water before, now I pay $1 by using cold. And my clothes are just as clean. Today’s washers- and detergents- are so advanced, you don’t usually need hot water. In our house, it also means less worry about colors bleeding into the wash.
Set the spin cycle to high and your clothes will come out drier and take less time in the dryer (if you use one).
