Televisions are labelled on an energy efficiency scale ranging from A++ (most efficient) to G (least efficient). Since January 2017, an A+++ label has been available for the most efficient televisions. These ratings take into account screen size. The annual energy use indicated on the label assumes televisions are on for four hours a day on average.
The European Commission provides tools for generating energy labels for products on the EU market.
Ecodesign requirements requirements cover:
- energy efficiency
- product information
Standby and off mode
A wide range of electric devices can have standby and off modes.
These are required to switch into a low power mode (such as standby) after a reasonable amount of time and they must not consume more than 0.5 Watts in standby or in off mode.
EU energy labelling and ecodesign requirements will save up to 45 TWh per year by 2020 – the equivalent of the electricity consumption of Czechia. Up to 15 million tonnes of C02 emissions will also be avoided each year.
When a television is switched off, its energy consumption must be below 0.3 W, and if it is in standby mode its energy consumption must be below 0.5 W or 1 W depending on the type of reactivating function it has. For televisions that remain connected to the network when in standby mode, energy use cannot exceed 6 W (falling to 3 W from 2017).
Moreover, televisions should go to standby mode after four hours or less following the last user interaction.
