Contrary to what the reassuring red button would suggest, the consumption of a TV on standby is not that trivial. By taking the reflex, each time your television is switched off, you will be able to make substantial savings on your energy bill to unplug it. To convince you, here is a focus on the consumption of a TV on standby.

What is the average consumption of a TV on standby?

Before the 2000s, electronics manufacturers had not mainly worked on the consumption of television going to standby. Thus, a television at the time could consume up to 30 watts on standby. Agreements were signed in 1997 at the European level to reduce this figure to between 1 watts and 3 watts.

Today, most TVs on standby therefore only consume 1 to 3 watts. However, television that remains on standby for 20 hours a day will consume between 7.3 kWh and 21.9 kWh per year, i.e. a cost of between 1.1 and 3.5 €. If this sum seems low, transposing it to the French level gives an overview of the extent of the problem, which amounts to between 49.5 and 140 M € per year for 40 million televisions.

What is the difference between LED, Plasma and LCD?

The consumption of a TV on standby also strongly depends on the type of TV chosen. Indeed, an LED TV, like a low consumption lamp, will consume significantly less energy than an LCD or Plasma screen, whether it is on standby or in operation.

The table below shows the various consumption data of a television set according to its technology and use:
 

TV typeAnnual consumption in operationAnnual consumption in standby
LCD TV241 kWh22 kWh
Plasma TV402 kWh22 kWh
LED TV54 kWh2.2 kWh

It is thus possible to see that an LED model makes it possible to reduce by ten the consumption of a TV on standby. Let’s compare the figures for televisions in use. The difference is eloquent, with a ratio of 1 to 4.5 between LED and LCD televisions and 1 to 7.5 between LED and plasma televisions.

Get into the habit of unplugging your television

To avoid wasting money and energy unnecessarily, making a habit of unplugging your TV after watching it is effective. On the other hand, it is not always easy to lean behind your TV and pull the plug to disconnect it completely.

To make your task easier, you can, for example, connect your television to a power strip with an indicator light. The reflex of pressing the switch will be easier to take.

Finally, if you are a fan of home automation, it will also be possible to equip your home to control your equipment remotely. Home automation will allow you to switch off your television remotely if you have forgotten and even configure alerts so that you do not forget to do so.
