The Minnesota Department of Commerce suggests upgrading to a new ENERGY STAR model to help you save on your utility bills.
ENERGY STAR is the government-backed symbol for energy efficiency that helps save money and protects the environment through energy efficient products and practices.
Dishwashers made before 1994 will cost an average of $40 more in energy costs annually than a new ENERGY STAR model.
A dishwasher built before 1994 wastes more than 10 gallons of water per cycle. A new ENERGY STAR model will save an average 1,300 gallons of water over its lifetime. It is about 15 percent more water efficient than standard models.
Nearly 70 percent of U.S. electricity is generated by burning coal and natural gas, which releases greenhouse gases and other air pollutants into the atmosphere.
Modern certified dishwashers use less energy than conventional models, which helps reduce air pollution and combat global climate change.
Energy experts recommend not pre-rinsing dishes. It wastes hot water and is unnecessary with newer dishwashers. A simple scrape to remove the biggest chunks is usually sufficient.
Use the least amount of detergent that will still clean your dishes. Excess detergent use can lead to spotting or etching, as well as some environmental concerns.
