Washing your clothes in cold water not only saves you money, but saves energy as well!
Wash a full load in cold. Unless you're dealing with oily stains, the cold water setting on your machine will generally do a good job of cleaning your clothes. Even switching your temperature setting from hot to warm can cut a load's energy use in half.
An easy way to go green!
**If you are washing a small load, always make sure to use the appropriate water-level setting.
