Modern TVs are becoming more and more energy efficient, but electricity consumption remains an important issue for users.
Glavred will tell you how much electricity a TV consumes in 1 hour of operation, how many kilowatts a TV uses per month, and how much the TV uses when turned off in standby mode.
Main factors of electricity consumption
The electricity consumption of a TV depends on many factors. parameters:
Screen technology:
- Tube transistors and cathode ray tubes (older models) consume more energy.
- Light emitting diodes (LED), liquid crystal (LCD) and OLED screens are more economical.
- Gas discharge elements and plasma screens are less energy efficient.
Screen size:
The larger the diagonal (for example, 85 inches versus 24), the higher the energy consumption.
Energy efficiency class:
TVs with A+++, A+++ or A+ ratings consume less energy compared to devices in classes B, C, D.
Additional features:
The presence of Smart TV, Wi-Fi, Bluetooth and powerful audio systems increases energy consumption.
Standby mode:
A switched off TV in standby mode consumes from 0.3 W to 1 W.
How much electricity does a TV consume in 1 hour of operation?
How many kilowatts does a TV consume per month?
Calculations for an average user who watches TV 4 hours a day:
- LED TV: 0.08 kWh × 4 hours × 30 days = 9.6 kWh per month.
- OLED TV: about 12-15 kWh per month.
- Plasma TV: up to 30 kWh per month.
If the TV is on for longer or is used more intensively (for example, in background mode), energy consumption increases.
How much does a TV with the power off consume?
In standby mode, the TV consumes minimal power, typically 0.3-1 W. In a month it is:
0.5 W × 24 hours × 30 days = 0.36 kWh.
Although this is a small amount, it can accumulate if there are many such devices in the house.
How to determine real electricity consumption
According to the documentation: The manufacturer indicates average energy consumption.
Using a meter: Turn off all devices except the TV and check its energy consumption per hour.
Using wattmeter: The device will show the exact power value.
