Cold water works

Wash your clothes in cold water. It works and they make detergent just for that. Hang em up to dry if you need that fabric softener touch then wait till they're dry and fluff with a fabric softener sheet. Besides saving the energy using the dryer if the dryer is inside you saved the energy to overcome the heat the dryer produced. By now this should be becoming tiresome, repetitive and obvious. If you generate heat then you are paying to do so. If you generate heat indoors you are paying twice. Once to generate it and once for the climate control to overcome it.
