Saving electricity in the kitchen
How much does it cost to bake a ready made pizza?

Energy is becoming increasingly scarce and expensive. So it’s worth saving up for. Also in the kitchen, when baking and cooking. This area represents about eleven percent of the total annual electricity consumption of an average household of three people. Read here how you can save here.
Food intake is not only a necessity, but also a quality of life. To make food easier to digest and taste better, it is cooked, baked, boiled and baked. This requires a stove and also energy. It’s expensive right now. A good reason, then, to pay attention to electricity consumption when using the kitchen.
Baking and cooking account for about eleven percent of annual electricity costs in an average household of three. Modern stoves have significantly lower power consumption than old appliances. Regardless, electricity can always be saved in everyday life with simple tips on the stove and in the oven, as the “80 million together for the energy change” campaign of the Federal Ministry of Finance and the Environment shows.
Let’s start with the oven
Most people have no idea how much electricity an oven uses. Here are some examples:
- Bake a cake once: about 40 cents
- For three casseroles/roasts in a week: about 77 minutes
- Bake ready-made pizza: about 17 cents – with one ready-made pizza a week, that adds up to €9 a year
How can power consumption be reduced when baking?
- If you bake several times in a row, you avoid reheating twice: first put the marble cake in the oven for the afternoon, then the lasagne for lunch.
- Buns should be baked in a toaster with a bun warmer. This saves 70 percent energy compared to an oven.
- Convection is about 20 percent more economical than top and bottom heat because you can cook at a lower temperature. The temperature can be set about 20 to 30 degrees lower with circulating air.
- Preheating is often not necessary. This saves even more electricity. The oven should only be preheated for delicate foods such as certain types of pastry or fillets.
- “Smart Home” functions and WiFi in the oven should only be activated when required, otherwise standby power consumption will increase. Rapid heating programs and the self-cleaning function (also called pyrolysis) are very energy-intensive and should only be used for cleaning purposes.
- Savings example: If a ready-to-eat pizza is prepared in the oven, more than 20 percent of energy can be saved with the most efficient cooking method (convection without preheating) compared to the most inefficient method (top and bottom heating with preheating).
And now it’s time for the hot dish
Regardless of the type of stove, you can cook energy efficiently. Cooking without a lid, for example, uses up to three times more energy than when the pot is covered. Or expressed in numbers based on the energy consumption to cook 500 grams of potato: With a pot without a lid filled with a lot of water, you need about 0.5 kilowatt hours (kWh) on a glass ceramic hob. That’s about 15 cents per cooking process. If, on the other hand, you use the pot with a lid, you only use about 0.25 kWh. Consequently, the cost of electricity per cooking process is halved.
How can electricity consumption be reduced while cooking?
- A (flat) pot or pan bottom saves up to 30 percent energy if the size of the pot matches the hob.
- Steam cooking: If less water is used for cooking, energy can be saved. One to two centimeters of water is enough to steam potatoes, eggs or vegetables. Because not only do you have to heat less water, but of course it also heats up faster.
- Pre-cooked cereal products: Noodles cook faster if they are heated with water and not put in boiling water first.
- Use residual heat: Even if the electric cooker is switched off five to ten minutes before the end of the cooking time, you can achieve the desired result.
