Use less hot water, and you’ll not only save on energy costs, you will reduce your water bill and help preserve natural resources, too. Run your automatic dishwasher only when full, and wash and rinse full loads of laundry in cold water. Install low-flow showerheads, and don’t forget to check for and repair plumbing leaks. All it takes is a few changes in your normal habits and a small investment or two to start using a lot less energy.
