Wash your laundry in cold water.

Why: Washing just four out of five loads in cold water will save 72 pounds of CO2 emissions in one month alone. It will also save about $60 in energy costs for the year. Additional benefits of washing in cold water include lengthening the life of your clothes and helping to fight stains on most fabrics. (But will my clothes get clean?)

How: There are two ways to reduce energy use when washing clothes:

• Use less water - Wash only when you have a full load, or set the water level to "low" or "medium" when washing smaller loads.
• Use cold water - Select the “cold/cold” option on your washing machine.
