According to the California Energy Commission, the typical Amercian household, does nearly 400 loads of laundry per year. A conventional washer uses about 40 gallons of water per load. If you cut that down to only 4 loads in a week, you would be cutting that number in half. Using cold water is helpful as well. The California Energy Commission states that up to 90% of the cost of washing clothes comes from heating the water, so use hot water only when necessary.
I have briefly mentioned previously why conserving water helps. As our population grows, while our water supply stays the same, we need to take care of it and use it wisely since it is essential to life for us. Conserving water helps to save the environment when it stays in it’s reservoir, it means less energy required to process and deliver it (meaning less pollution and saving on fuel resources), and helps to build a better defense against future droughts.
We now designate one day of the week for doing wash, Wednesdays. It makes it much easier to ensure full loads rather than numerous small ones and it saves water, money and time.
