Kitchen Appliances

Purchase/Installation
  • Consider buying thermal cooking pots as they significantly cut down energy required for cooking. The ingredients need only be brought to a boil (up to ten minutes) before being placed in the insulated thermal pot. The retained heat will cook the food without additional heat input from the stove. A meal normally requiring an hour’s worth of cooking can use as much as 80% less energy.
  • Consider buying pressure cookers as they consume less energy and cook food faster. By cooking food at a higher temperature and pressure, a pressure cooker can save up to two-thirds in cooking time and cut energy use by 50 - 75% as compared to conventional methods.
  • Consider using a thermo-flask to keep hot water. Electric air-pots which keep water hot constantly can add about $25 a month* to your electricity bill.
  • Choose a kitchen sink tap with one or more ticks on the WEL. The more ticks on the label, the more water efficient the model is.

  • Install thimbles or water saving devices on taps to reduce the flow rate of water.

Usage
 
  • Do not boil more water than you need.
  • Thaw frozen food before cooking. This can reduce the cooking time.
  • Use small appliances whenever possible for cooking or heating smaller amounts of food as these are more efficient.
    • Use a bread toaster rather than a conventional oven to make toast
    • Heat food in a microwave oven rather than a conventional oven.
  • Cover your pots while cooking. Food cooks faster in covered pots.
  • Match the size of the pot with the size of the burner as the energy is lost when the heating element is larger than the pot you are using.
  • Turn down the heat once cooking temperature or state is reached; simmer food rather than boiling it.
  • Turn electric hotplates off before the food is fully cooked, as the heat from the hotplate will continue cooking the food for a while.
  • Avoid opening the oven door while cooking.
 
 
Other Green Tips
 
  • Thaw food hygienically at room temperature or in the lower compartment of your refrigerator, rather than using a microwave / conventional oven or putting it under running water.
  • Bring your own reusable food containers when buying takeaway food.
  • Buy dishwashing refill packs instead of new bottles.
  • If you use a dish rack tray, remember to remove the collected water every other day and scrub it thoroughly to remove any mosquito eggs.
 
 
Fun Facts
 
  • You can save 14 litres of water by washing vegetables and dishes in a filled sink instead of under a running tap.
  • Food waste constitutes about 20% of waste disposed of in Singapore. You can help to reduce food waste by planning your grocery shopping and food purchases well so as to avoid buying excessive food. Also, prepare and cook only what you need for consumption.
