Which TV consumes the most electricity?

3 min

Crime, drama, comedy – the television program offers the right entertainment for every mood. In order to avoid more electricity costs than absolutely necessary during a relaxed evening watching TV, you should pay attention to its technology and energy efficiency class when buying your TV – and from now on the new EU energy label.

In the living rooms, two different types of TVs are currently providing entertainment: conventional LCD / LED TVs and OLED TVs. Unlike in the past, tube and plasma TVs no longer play a role today. Anyone who still owns one has a real power hog in the living room.

In general, the energy consumption of televisions depends on several factors, such as the resolution and HDR support. Basically, the higher the resolution and the stronger the HDR effect, the more energy the TV needs. The following guide values ​​apply for 1,000 operating hours:

  • With 50 to 55 inches: Low consumption is around 60 kilowatt hours – around 18 euros per year.

  • At 65 inches: Low consumption is around 80 kilowatt hours – around 24 euros per year.

OLED TVs are considered, at least in theory, to be particularly energy-efficient – and perform better in this category than LCD and QLED TVs, for example. In practice, however, LCDs and OLEDs are often on the same level because the preset brightness in OLED devices is usually very high.

Hidden energy thieves in TV sets

Not only the technology, but also the size of the display determines the power consumption during operation. Large screens draw more electricity than small ones. Because: With the size of the screen diagonal, the screen area increases and the required background lighting also increases. For example, a double diagonal not only quadruples the size of the screen area, but also the energy requirement. In addition, energy-intensive extras such as several powerful speakers contribute to a crisp electricity bill.

Energy efficiency class as a savings guarantee

Almost all household appliances have to be assigned an energy efficiency class according to their power consumption. Until February 2021, the scale for televisions ranged from energy efficiency class A + for very economical devices to energy efficiency class F for inefficiently working devices with very high energy requirements. On March 1, 2021, however, a new EU energy label was introduced, the scale of which only extends from A to G.

In addition, the new EU energy label 2021 contains the following energy-related information:

  • A QR code that leads to an EU product database and provides further information about the television.
  • The efficiency class of the TV.
  • The energy consumption in kWh per 1,000 hours of use.
  • Separate indication of energy consumption with and without HDR.
  • Visible display diagonal in centimeters and inches and resolution in pixels.

energy label TV

This is what the new and current EU energy label for TV sets looks like.

In addition to the energy label that every company must use to mark their televisions before they are sold, the manual that comes with the product also provides information on the energy consumption of the TV set. Here you will usually find two different measurement bases: the consumption of the device in standby mode and the consumption of the device during operation.

Compare TV sets correctly

In order to be able to compare the power consumption of different models when buying a television, you should make sure that they have the same screen size. As a guide for choosing the right screen size, the following rule of thumb applies: The screen diagonal times three results in the optimal sitting distance – i.e. the distance between the couch and the place where you want to set up the new television. Further comparison criteria are the kWh consumption per year and the power consumption of the television.


  1. At the moment there are primarily LCD / LED and OLED TVs.
  2. Tube televisions consume the most electricity, whereas plasma televisions consume more energy with plasma and LCD / LED screens with the same screen diagonal – but both categories of devices are no longer sold in stores.
  3. The power consumption of the device increases with the size of the screen diagonal.
  4. The energy efficiency scale for televisions ranges from energy efficiency class A for very economical devices to energy efficiency class G.
  5. In order to be able to compare the power consumption of different models when buying a television, they must have the same screen diagonal.
