Price question: Where in the household do the biggest power guzzlers lurk? Certainly in the living room, where the oversized flat screen and the game console run half the day. No! Or is it in the bathroom? After all, washing machine, hairdryer, tumble dryer and the like are no children of sadness when it comes to electricity consumption. Close but also wrong.

1. Defrost the freezer regularly

Freezers and iceboxes are among the secret bulk consumers in the household. After all, they are in operation 24 hours a day, 365 days a year. This is precisely why the appliances should be kept as free of ice inside as possible. After all, a layer of ice a good centimetre thick already ensures that the energy consumption of the appliances increases by 10 to 15 percent. So anyone who neglects de-icing for convenience is giving away a lot of money.

2. Setting up the refrigerator correctly

Let's stick to refrigerators. The refrigerator is also a permanent fixture in the kitchen. But a few simple tricks are enough to reduce energy consumption. Even when planning the kitchen, two things should be considered that unnecessarily increase the energy consumption of the refrigerator. Firstly, the refrigerator should not be placed directly next to large heat-generating appliances such as the oven, the ceramic hob or the dishwasher. Secondly, if possible, the fridge should be placed as far away from the window as possible. This is because the refrigerator has to work additionally even when exposed to the sun for hours on end.

3. Optimal use of the refrigerator

Before we get to the really hot topics, a few tips for the efficient use of the refrigerator: The best way to save energy is to fill it up properly. The ideal level is 75 to 80 percent. In this way, the food in the fridge takes on the function of a cold pack by taking up the volume and storing cold.

If the refrigerator door is now opened, the volume of air in the refrigerator is lower, which means that only a small amount of cold air can escape. So less air has to be cooled again after closing the door. A notoriously empty fridge, on the other hand, allows a lot of cold air to escape every time the door is opened, which costs money. Furthermore, it goes without saying that hot food does not belong in the refrigerator. Only when they have cooled down to room temperature are they allowed inside.

4. Every pot has its lid

Even if the chilli and mushroom cream soup still smells delicious, a lid belongs on every pot. Otherwise, sniffing becomes expensive fun. After all, depending on the composition of the pot, up to 40 percent of the energy is lost unused. And cooking without a lid takes longer - real torture for the stomach and the wallet.

5. Using the kettle

Heating water is one of the most energy-intensive processes of all. Worse still, with every degree by which the water is additionally heated, energy consumption increases. Anyone who wants to keep energy costs under control here should not bring their pasta, rice or potato water to the boil directly in the pot, but should take this step with the kettle. The heating of about 3 litres of water, as it is needed for a large pot of noodles, costs only about 6-8 cents. On the stove, it is easily double that.

6. Use the residual heat

If you are not using a gas stove, you cannot switch off the heat output of your stove at the touch of a button. This is a big problem because a lot of heat and therefore energy is lost unused as soon as the pot is taken off the plate. It is better to switch off the cooker 4-5 minutes before and finish cooking the food with the still sufficient residual heat. Also, this small Lifehack saves 30 to 40 Euro on a yearly basis.

7. Bake with the air circulation function

Baking is fun, no matter whether you have chocolate muffins, cupcakes or cheesecake in the oven. But the sweet sins taste all the better with the certainty of saving energy at the same time. And this is done quite simply by using the circulating air program instead of the top/bottom heat. In this way, a good 30 degrees Celsius less are required for baking, which reduces energy consumption and the amount of energy needed for baking.

8. Do not wash by hand

Laziness is rewarded! At least when it comes to washing up, that's the case. If you do the dishes by hand, it takes not only half an eternity but also a lot of water and energy. Of course, it makes sense to scrub particularly heavily soiled parts by hand. However, the majority should end up in the dishwasher and be cleaned there with the energy-saving program. The bottom line here is an energy saving of up to 50 percent. In addition, water consumption is reduced by up to 75 percent.

9. Rely on LED lighting

The lighting in the kitchen is also a real energy guzzler. After all, when working with knives, kitchen appliances and hot pots and pans, the work surface should be properly lit for obvious reasons. LED lamps promise enormous savings potential here. Thanks to their versatility, they are suitable both as under-cabinet luminaires for the cooker and for illuminating the worktop and also for illuminating the dining table in a pleasant light. Depending on which light sources were previously used, savings of 25 to 90 percent are possible.
