Did you know that a recent study showed that washing dishes by hand uses more energy than using a dishwasher? The electricity in a dishwasher is used to heat up the water, which is then pumped and recycled around the machine. The less water used, the less electricity is needed to heat up the water.
Compared to washing dishes by hand, dishwashers use much less water. Handwashing uses up to seven times more water than a regular dishwashing cycle. Dishwashers also heat up the water more efficiently, which results in less heat loss than heating water in a tank and transporting it to the sink. In addition, the appliance is insulated to avoid heat loss from the interior space. All the more reason to use your dishwasher!
The truth behind dishwashing by hand:
Water used - 140 L
Energy used - 3.5 kWh
Time spent - 71 min
The truth behind using a dishwasher (at 3 levels):
Water used – Quick: 13 L /Normal: 18 L /Intensive: 27 L
Energy used – Quick: 0.9 kWh / Normal: 1.6 kWh / Intensive: 2.0 kWh /
Time spent: Quick: 39 min / Normal 131 min / Intensive 112 min
So, not only does the dishwasher save you time by doing all of the work for you, but it actually does it by using less water and energy. Even more of an excuse to never wash another dish by hand again!
