TV energy consumption..?

Stuart_W

I remember everyone going mad about the TV being left on "standby" and this causing a big problem, but as TVs get bigger I presumeenergy consumption is going up and up.

I am proud of my electricity bill and low carbon-impact.

However, I understand that firstly, in some instances, it can take more energy to receive digital signals, and as I will soon be needed to switch to digital (still quite happy on analogue with my little 14" TV without ssurround sound or HD ready or all the rest of it) I was wondering if anyone knew the energy - and therefore cost - implications of the different platforms.

Cable, satelite and freeview are all available to me, but freeview requires some recabling and a new ariel, cable have launched a free version if I switch my phone to them (which would be no problem if necessary) and Sky have a free version, too. Some come with boxes that need to stay plugged in, and I undertstand this "pause and rewind" live TV business means a hard drive in your box is constantly recording and wiping what you're watching. Sounds high in energy consumption. I want something I can turn off if I'm not watching it. Does a satelite dish need to be plugged in??

Which is the most energy efficient??
I am proud of my £14.00/quarter electricty bills. I don't want entering the digital age to ruin this!!! I am already aware that two minutes of winding on a dynamo-powered radio can get one hour of traditional radio or SIX MINUTES for digital radio. Is digital TV just as bad???

You could buy this little device and monitor, Hope this helps ?

My Sky + box(HDD Recorder) draws 17 Watts. The Sky box about the same. Both of these have the same consumption on Standby or switched on. So approx 4p a day.

My 32" LCD TV uses about 150 watts when on - approx 1p an hour. On standby the handbook says less than 1 Watt and it would appear to be quite a bit less than 1 Watt - pence per year.

A 32" Sony CRT TV uses 122 Watts when on and 0.6Watts on Standby and a 25 inch Panasonic CRT TV uses 76 Watts and 0.9 Watts on standby.

Combined DVD & VCR 22 Watts switched on.

I think that This is prolly going to be the lowest consumption way for you to get digital TV, it uses 2.2watt iirc.

A standard freeview box will be around 5watt, obviously if you get a combined HD/DVD-PVR and freeview box then consumption will go up.

I would think the opposite as most people are replacing CRT's with LCD's that use far less power.

Lots of people are buying plasma TV's as they are cheaper, But plasma sets can use up to four times as much electricity as the old-style cathode-ray tube models.

I would think LCD sales far outweigh plasmas

I'd be intersted in knowing how you manage to use less than 2 Kwh of electricity a day as thats what I reckon your £14/quarter roughly equates to,

I don't know, all the argos type shops are selling plasma screens off cheap compared to LCD (the cheapest 42" plasma is £700 at argos, compared to double that price for the cheaperst LCD of the same size).

Large screen TV's are the latest fashion, and most people just want the biggest for the cheapest price.

Yes Stuart, would be interesting .

Don't know, I use Domia Lite (now marketed as Bye Bye Standy) modules, operated by remote control. Also adds convenience to switching appliances off and on in general. Been using them for a couple of years and they were recently mentioned on the Gadget Show. Never heard of "Easy off", may be useful if you provide a link.
I'm guessing English isn't your first language, your posts are very difficult to understand.
