Yes, its true.
Really confused how do you know that then?

Actually a typical TV will use something like 5 watts, a VCR 5-10 watts. Some of the new TVs less than a watt.

By comparison a 42" plasma TV might use 400 watts turned on the a large tube telly maybe 100 watts

So at first sight it sounds like a lot of fuss over nothing but think for a moment how it adds up say a total of 20 watts on standby for all your devices by 10 million households 200 mega-watts

To put that in perspective the old Sizewell A magnox nuclear power plant consisted of 2 200 megawatt reactors.

So no it's not true, but yes it is a saving that's worth making



I used one of those power monitor meters on my tube tv and found that by leaving it on stand-by for a year it would cost me 30 quid.
There are 8760 hours in a year at 10p per KWhr that's �876 for a Kilowatt year which would mean that your TV would have to be using 30 watts on standby Heathfield.

That's way over average right on the upper end of standby consumprtion - time to get a new TV I'd say :c)

Incidently it looks as if standby mode may be banned
