When cooking on an electric range, use pots and pans that are properly sized to fit the burners. Using the right sized pot on stove burners can save about $36 annually for an electric range, or $18 for gas.
Cook food and boil water in a covered container whenever possible; it's faster and uses less energy.
Begin cooking on a higher heat setting until liquid begins to boil. Then, lower the temperature and simmer the food until fully cooked. A fast boil doesn’t cook faster than a slow boil, but it does use more energy.
Turn off cook tops or ovens a few minutes before food has completed cooking. Retained heat finishes the job using less energy.
Use small electric pans, toaster ovens, or convection ovens for small meals rather than your large stove or oven. A toaster or convection oven uses one-third to one-half as much energy as a full-sized oven.
Try to avoid peeking at the food you are baking in the oven. Each time you open the door, the oven temperature is lowered 25 degrees.
Use cold water when operating your food / waste disposal. Cold water saves energy and solidifies grease so that it will move through the drainpipes easier.
Place the faucet lever on the kitchen sink in the cold position when using small amounts of water; placing the lever in the hot position draws hot water even though it may never reach the faucet.
