Dishwasher Appliances account for as much as 20 percent of your energy bill. Newer, more efficient models save energy and water. If replacing your dishwasher, an ENERGY STAR® model can reduce your carbon footprint and save more than $25 a year in energy costs.
Sink To conserve water, repair any leaky faucets promptly. Hot water leaking at a rate of one drip per second can waste up to 1,661 gallons of water in one year—and wastes up to $35 in electricity or natural gas.
Refrigerator/Freezer If your current refrigerator was made before 1993, it uses twice as much energy as an ENERGY STAR® model. A 1992 top-freezer model with 19-21 cubic feet indirectly emits as much as 754 pounds of CO2 per year. A 2002 side-by-side model with 19-21 cubic feet indirectly emits as much as 442 pounds of CO2 per year.
Replacing an older model with a new ENERGY STAR® model can eliminate hundreds of pounds of CO2 each year and save $45-$65 per year on your electric bills.
Other tips: Keep your refrigerator at 37°- 40°F and your freezer at 5°F.
Vacuum the condenser coils (underneath or behind the unit) every three months.
Check the condition of door gaskets by placing a dollar bill against the frame and closing the door. If the bill can be pulled out with a very gentle tug, the door should be adjusted or the gasket replaced.
Do not put uncovered liquids in the refrigerator. The liquids give off vapors that add to the compressor workload.
Microwave Use your microwave oven whenever possible. It draws less than half the power of its conventional oven counterpart and cooks for a much shorter amount of time.
Range/Oven Only use pots and pans with flat bottoms on the stove. Use the right-sized pot on stove burners. A six-inch pot on an eight-inch burner wastes more than 40 percent of the burner's heat.
Develop the habit of "lids-on" cooking to permit lower temperature settings. Keep reflector pans beneath stovetop heating elements bright and clean.
Begin cooking on highest heat until liquid begins to boil. Then lower the heat control settings and allow food to simmer until fully cooked.
Cook as much of the meal in the oven at one time as possible. Variations of 25°F still produce good results and save energy.
Rearrange oven shelves before turning your oven on—and don't peek at food in the oven! Every time you open the oven door, 25° to 50°F is lost.
Trash Recycle your newspapers, plastic and glass containers, and paper products. By cutting the amount of waste you produce in half, and doubling the amount of recycling in your household, you can save about 1,200 pounds of CO2 per year.
