The easiest way to save energy when using your washing machine is to always use cold water; it helps protect the clothes, and today's detergents are designed to work more effectively with cold water. By not washing with warm or hot water, you can save 4 percent off your total household energy bill. Also, always err on the side of using less detergent rather than more. Using too much detergent can actually clog your machine and force it to work harder to remove the excess suds.
