Use a high-efficiency washing machine
A high-efficiency clothes washing machine can reduce water consumption by 40% and energy consumption by 50%. As added bonuses, they use less detergent, help your clothes last longer, and take up less space.
Using a water efficient washing machine and dishwasher saves both water and energy.
When the time comes to replace your existing dishwasher or washing machine, opt for high efficiency water saving ones. These models are also energy efficient. Water efficient dishwashers save not only water, but energy too, because 60% of the energy consumed by a dishwasher is for heating water. While shopping for a dishwasher, you should look for an energy efficient model with the Energy Star label, but you should also look for water efficiency. Some Energy Star models are more water efficient than others. Prior to 1994, dishwasher used around 15 gallons of water per cycle, but today there are models available that use as little as 4 gallons. Front loading washing machines tend to use much less water than top loading ones, and they also reduce the drying requirements, so you’ll save energy on drying too.
Another water saving tip is to only run the dishwasher on a full load. In addition, you should also run full loads in your laundry machine. Running your washing machine on only a full load can save a typical home thousands of gallons of water annually.
