Using your dishwasher greenly:
Many believe that using a dishwasher saves on water but that's not always the case. But with a dishwasher, you can run it as needed, which for some households might be once or twice a week. Many dishwasher models cite pre-rinsing as unnecessary, using water pressure to replace the pre-rinse. If you scrape off food residue with a spatula, however, and use a shorter wash cycle – that will reduce the long wash and regular long rinse to save on water. Shortening the dishwasher cycle will cut operating time and also reduce energy use. If you want to maximize energy savings, use the econo-dry setting to save on electricity.
