Does a TFT monitor use less power than a CRT monitor?

Does an LCD TV use less than a CRT television?

For the same screen size, yes. An example of declared typical power consumption is below.

Dell 17” LCD (1707FP) ... 32W
Dell 17” CRT (E773c) ..... 68W

Dell 24” LCD (2407WP) .. 57W

The same goes for TVs.

As Alfie has already said a TFT screen does use less power than a CRT screen.

In fact studies have shown that for say a 15" TFT the extra energy saving you make on a TFT screen versus a similar CRT screen means you can pay off the total cost of the purchase price of a TFT screen in approximately 4-5 years just on its energy saving alone.

Whilst the LCD display itself on a TV presumably uses less power than a CRT TV display(as they certainly do on PC monitors) it would be a mistake to assume that all LCD TV's use less power than older CRT TVs.

My 6/7 year old 32" Sony uses 122 watts and 28" Panasonic 81 watts. My newish 32" HD ready LCD TV uses 160 watts.

Plasma TVs use a lot of power 400-500 watts is not unusual.

If your thinking of upgrading to TFT to save energy and do the Earth a favour don't forget about all the kWh needed and CO2 produced during its manufacture, marketing & distribution. Not to mention your old crt which may end up in landfill.

2kW is amazing, I saw some new ones about 600 watts.

Whats the betting that will inspire a money saving idea:

Use your Plasma TV as a toaster.
