Simple ways to save power.

We are all aware of the fact that the pot or pan is not hot enough as soon as we switch the hot plate on. It takes a little while for the plate and pot to heat up. In the same way, it takes a little while for them to cool down so if we switch off the power about 5 minutes before the food is cooked, it will still continue cooking in the hot pot on the hot plate.
· Use the kettle sparingly. A kettle is rated at about 2 kilowatts. Boil only enough water for your needs. If you are making one cup of coffee, boil one cup of water. This reduces the amount of time the appliance is working. Another option is to use a thermos flask or pump pot. Boil a full kettle and then pour any unused boiling water into the pump pot. For the next two hours you can use the water for making coffee or if you need it really boiling for tea, pour it back into the kettle and it will take much less energy to heat it up the last couple of degrees.
· Use the microwave instead of the hot plate as often as possible. Most food cooks faster in a microwave.
· Other options are a pressure cooker (which cooks faster because the high pressure enables the temperature to get much higher) an electric frying pan or steamer, where different foods can cook at the same time by stacking up on top of one another.
· On an electric stove top, use pots and pans with flat bottoms to maximize surface area and use a hot plate the same size as the pot.
· If you have to use the oven, make sure the seals fit properly to reduce heat loss. Test by closing a piece of paper between the door and the oven. If the paper slips out, you could be losing a lot of heat. Replace the seal to avoid wasting energy and money.
· Cook more than one dish in the oven at a time or one pot dishes on a stove top.
· Consider cooking in bulk and freezing, using the microwave to heat the dish.
· Thaw food overnight in the fridge rather than in the microwave.
· Keep the lid on when possible to reduce heat loss
· Dishes requiring browning in an oven eg macaroni and cheese use a lot of electricity just to get the cheese topping browned. Five minutes under a TV grill will give the same result with far less energy consumption.

  • It costs almost the same to buy a roast chicken from most supermarkets as a fresh one. You save not only the electricity that you would use to cook it, but also the human energy you would use.
  • Use insulation. We are so used to the concept of warming up food quickly in a microwave that we no longer try to keep it hot. Any insulating material wrapped around a pot or dish will help keep it hotter for longer. Examples are – newspaper, corrugated cardboard, blankets, packaging materials. The Wonderbox is an example of how food can not only be kept warm but continue to cook without the use of any electricity at all.
