How to choose an eco-friendly TV

Most new televisions have an LCD or a plasma screen, not the traditional cathode ray tube (CRT).

It’s easy to see the appeal of the new-style televisions: they’re sleek, sexy and space-saving.

But plasmas also consume more energy than the old CRT models.

An old-style television can use as little as 90 W of electricity compared to up to 390 W for a plasma screen or 270 W for LCD.

But for the equivalent size LCD is better than CRT.

The big picture

With screen sizes getting bigger, so the energy use increases.

Currently, 92% of TVs are CRT, but this figure is expected to be 52% by 2010.

By 2020 they’re expected to be a thing of the past.

What to look for

The most sensible energy-saving sets are known as IDTV (integrated digital television).

These have a digital set-top box built in, meaning you get two appliances but only one plug.

Unlike many set-top boxes they can be switched off completely without losing any settings that have been made.

Choosing an IDTV will save you 25 kg of carbon dioxide a year.

If everybody chose IDTV, the combined savings across the nation’s 60 million TV sets would be close to 1.5 million tonnes of carbon dioxide.

According to Government estimates, there could be 80 million set-top boxes in the UK by 2010.
