Save When Doing the Laundry
From Jeffrey Orloff, former About.com Guide
Simply heating the water to wash clothes amounts to 90% of the washing machine's power consumption. The best way to save money when you are doing the laundry is to wash clothes in cold water. When used with cold-water detergent, washing in cold water is actually better for your clothes. Oily stains that require hot water for removal can be switched from hot to warm still saving energy and doing a good job of cleaning your laundry.
