Which appliances and activities eat the most electricity?

At a time when a large part of people, not only in the Czech Republic, are nervously watching their electricity bills, among other things, and slowly recalculating every crown in their pocket, it is useful to look for which appliances or activities they actually need one in the household electricity the most. If, for example, you already have smart sockets or other measuring devices at home, answering such a question is a piece of cake for you. But most people don’t use such a solution yet, so it fits at least to remind generallyin which values ​​the electricity is approximately consumed by individual devices or operations.

If you’re going to argue that it’s enough to read the wattage label, you’re partially right. But first of all, the device may not always reach this value and… and this is even more important… probably few people want to look at these labels and probably few of us remember the values ​​from them. For that reason, it is good to have at least basic overviewwho are the biggest gluttons and therefore i potential savers. Electric heating is omitted from the overview, which would otherwise understandably be in first place.

We are talking here about common household items and their standard consumption values. It goes without saying that, for example, a “powerful” gaming computer will consume much more than a normal laptop, etc.

1. “Wet” heating appliances

Any large or small appliance that in some way uses electrical energy for heating and works mainly with water. The most prominent examples are the washing machine, dishwasher and dryer. Their consumption has a share of about 14% in the entire household. Savings can then be made not only by less frequent use, but especially by by choosing more economical modes and by lowering the working temperature.

2. Refrigeration appliances

In short, a refrigerator aka fridge and freezer. Their immediate consumption may not be exactly astronomical, but it is necessary to realize that they are the majority on 24/7. And since they can usually withstand repair for a long, long time in the home, it is very reasonable to think about long-term consumption when choosing them. It accounts for about 13% of the electricity bill.

3. Consumer electronics

The modern household is teeming with smaller electronics that already in terms of consumption, it surpasses, for example, lighting. We can include the TV, computer, Hi-Fi towers, consoles and, last but not least, charging mobile phones and tablets. This is about 6% of consumption in the entire household. With consumer electronics, it is good to think about the so-called stand-by mode.

4. Lighting

Quite possibly the first area in which many people try to save immediately by buying more energy efficient devices. Buying other bulbs or lamps is not a big expense and the chance to reduce consumption is not entirely small. This is about 5% of the entire household. They play a positive role here especially LED lights.

5. Cooking

Hob, electric oven, microwave or kettle. Together, these represent about 4% of the total electricity consumption in a typical household. You probably guessed that it will be more, right? Of course, it depends on the frequency of their use.

This article belongs to the new long-term series “smart energy”. Within it, for example, you can look at 5 types of products with which you can save.
