This Little Trick Saves Your Clothes (And lots Of Energy)
According to the U.S. Department of Energy, as much as 90% of the energy used to wash clothes in a conventional machine is used for heating the water. The heat used to create hot water can lead to five times as many greenhouse gas emissions than when clothes are washed in cold water.
Remedy? Wash with cold water when you can. With the evolution of cold water detergents and modern washing machines, your clothes will still be clean without the heat. With proper cold water detergent and by not overpacking the load, you can expect squeaky clean results. The only exception to the new cold water rule is when a family member is sick with an infection or if you are washing exceptionally soiled items like cloth diapers.
As an added benefit, not only can you save money by saving energy, but also by preserving clothes. Hot water is much harsher on textiles and vibrants dyes which leads to faded clothes. Cold water helps garments retain their color, shape and size and the fabric’s overall lifespan...saving you money through and through.
