Be sure to 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 uses energy to heat the water even though it may never reach the faucet.
If you need to purchase a natural gas oven or range, look for one with an automatic, electric ignition system. An electric ignition saves natural gas because a pilot light is not burning continuously.
In natural gas appliances, look for blue flames; yellow flames indicate the gas is burning inefficiently and an adjustment may be needed. Consult the manufacturer or your local utility.
Keep range-top burners and reflectors clean; they will reflect the heat better, and you will save energy.
Use a covered kettle or pan to boil water; it’s faster and it uses less energy.
Match the size of the pan to the heating element.
Use small electric pans or toaster ovens for small meals rather than your large stove or oven. A toaster oven uses a third to half as much energy as a full-sized oven.
Use pressure cookers and microwave ovens whenever it is convenient to do so. They will save energy by significantly reducing cooking time.
