Wash all your clothes in cold water. Modern detergents can get clothes just as clean either way. One hot water load uses five times as much energy as the same load washed in cold water.You can save $100 a year by using cold water every time.
Also if you leave it on one station in the morning instead of punching around, you can save thousands of pounds of frustration. We make it flow. Good flow is what life is all about.
