Televisions keep getting bigger and better, but high-resolution brightness of color consumes a lot of power. But there are some tricks to determine and reduce consumption.
The way we watch TV is constantly changing. The device is running on demand more and more often, and for many people linear television programming is a thing of the past. What hasn’t changed, however, is that TV sets require electricity. How much depends on several factors, which ideally should be taken into account before buying. This way you keep your television’s power consumption under control.
How much power a television actually uses can vary dramatically from model to model. To calculate the consumption, it is important to know the power of the device. It is given in watts and can be found, among other things, on European energy labels, which manufacturers must recognize. A revised label was issued in March 2021, making the distinction clear to consumers. Confusing categories like A++ are no longer available, instead only classes from A to G.
Once the power is determined in watts, you multiply your daily TV consumption by this and multiply the result by 365 to determine the television’s annual power consumption in kilowatt hours. For example, if you have a device with an output of 100 watts and use it for three hours a day, the annual cost of electricity would be just over €30 at an electricity price of 28 cents per kilowatt hour.
reduce power consumption
Televisions require a rule of thumb: The bigger the device, the more power it will consume. However, consumption also depends on which technology is being used. LED, LCD, OLED and Plasma TVs are most commonly used today. On average, a 40-inch LED TV consumes 70 watts per hour, LCD TVs 100 watts per hour, OLED devices 150 watts per hour, and plasma models 175 watts per hour. From this it is clear that the greatest saving potential lies in purchases.
More savings potential is hidden behind the location of the TV set. If the television is in a slightly darker area where it is not exposed to direct sunlight, it can usually be operated with a lower brightness. It is best to plan for this factor in advance when setting up your four walls.
Plus, there’s an always-present standby tip: Simply turning off your TV with the remote control and leaving the room turns it into a secret power gauger. It’s better to turn it off completely or disconnect it completely from the power supply using a power strip, ideally with other Hi-Fi devices.
