Cool Fact! Every 10 degree drop in water temperature saves you about 3-5% on water heating costs!!! Can you believe that? So, try to wash your hands in cold water vs. hot/warm because it actually kills the same number of germs. It’s the scrubbing that rids your hands of dirt and germs (plus a biodegradable soap). Towels and sheets can be washed in warm water rather than hot to save energy. If you’re up for the challenge, try taking a cold shower! hee hee hee Or shoot for a warm one at least!
