Well if you can afford HD Subscription then whats the worry

Perhaps because the same amount of energy costs a hell of a lot more than it used to, not to mention the greenhouse gas emissions. Work out the energy requirement for all the sky boxes consuming over 20W in sby in the UK.

How have we got to subscription
, We currently have 4 free HD terrestrial channels and 5 on satellite.

OK so me saving a few watts will help the world, whilst the Americans + china etc are pumping out gasses by the bucket load

You walk into a shop for a new tv and the 1st question you ask is how much electric does it use

they are free because they are very limited, you cant watch sports or movies.
I asked if I could get a discount for buying the tv and home cinema at the same time and to hell with power usage. BTW I got £100 knocked off each

You are aware that the quoted figures aren't real?, and are theoretical maximums - hence their nice round values

Exactly, nice one.You can go buy yourself a nice new electrical appliance with the £100 and use more electric
Power and power saving is a political issue in this country. I use my common sesne and see that it is all a ruse to get more money out of the taxpayer for green things that themselves are a complete waste of money. Like windfarms.
Anyway 5W is about £5 per year if left on continously. Not worth worrying about.

Now we are getting stupid, but yes if I buy a new freezer I wan't it to be class A rated. It's worth paying more for this because it will save you money over a relatively short period. Would you not pay £20.00 more for a freezer that will save you £40.00 in Electricity in the first year ?
Would you use a Sky box to watch Free HD channels over a Freesat box and pay £25.00-£30.00 extra in electricity.
Given 2 cars one of which is the same size but has half the fuel consumption which would you buy.
If i was buying a new TV then also yes work out how much a 300W design will cost to run over a 150W one. Based on 8hrs/day and 16p/unit that will cost you £70.00 every year.
You clearly aren't struggling to make ends meet on a limited pension income, the word selfish **** comes to mind.
All totally irrelevant to this thread because given the same TV it doesn't cost any more to watch free HD channels than it does to watch the SD version.

They don't have to be real, simply based on the same assumptions. My 0.45A is pretty close at about 108VA.
I can however understand where your coming from. My wife bought a new washing machine and fridge freezer and both are A rated to save power and £ in the long run.

About £7.00 actually, based on an average unit price of 16p. 20 million users with an extra 5W equates to 100MW or £140 million pounds.
Every extra MW of demand produces proportionally more CO2 than the previous MW.
Power generation efficiencies vary widely with shiny new plant being a lot more efficient than older plant.
Adding 500MW to the national demand will produce a larger amount of CO2 than reducing the demand by 500MW will save, adding 1000MW will more than double the emissions of the 500MW increase.

The key was "similarly sized", you didn't get many 50" CRTs
.For the same functionality power has come down and will continue to come down but of course you get more functionality nowadays.
I expect most people who have both a sky box and a freesat box wouldn't turn off the sky box to watch the freesat box if they were watching something on the sky box beforehand.
I wouldn't buy a tv based on its power consumption. I'd go by picture quality. And pretty much nothing else.
For a car, I'd go by how it drives, how comfortable it is etc. Fuel consumption is quite a way down the list. I'd rather have a "sportier"car than one that was particularly frugal.
For something like a freezer, then yes as I can't get excited by a freezer!

This country's co2 emissions are low anyway. And do they really matter? Is global warming real or just another way of taxing the general public? Debate.

I don't see the relevance. While on they have similar power requirements.
When in sby the Sky box uses about 22W, the Freesat one 0.75W.

Or the fork lift to get the thing into the lounge
.I had a 16:9 36" flat screen Toshiba Picture frame crt. Boy was it heavy
36" was about the limit of the glass technology to build 16:9 tubes. There were if I remember correctly 40" 4:3 models.

Presumably a Sky HD box is similar, when put in the same shut down state as a Freesat box?.

It's not, to record from a timer a Sky+/Sky HD pvr box has to be virtually fully booted hence the 22W sby power. They added a super low power sby mode as a sop to the EU to the HD boxes (afaik Sky+ boxes don't have it). As it can't record from this mode you might as well just turn it off giving a super green 0W. The new multiroom non pvr has low power sby but as it's not a pvr again you might just as well turn it off completely

We are 12th in the world so hardly low. http://www.nationmaster.com/graph/en...ide-per-capita
Whether you accept man made climate change or not depends on whether you believe the same science that brought you these TVs or whether you believe those with no science but a vested interest in not limiting CO2 production.

No, I don't, because 5% in context matters or doesn't, 5% rise in the price of a candy bar is nothing, and has no relevance to a 5% rise in salary. Cheap is cheap no matter how you spin it.

Eh, I think crts especially large ones used a decent bit... in any case you aren't going to save money by upgrading as it would take an eternity for the tv to pay itself off in energy savings.
In any case if ones concern is carbon then its all green wash anyways, like solar on your roof as your tv is not all that significant a source of power consumption to begin with, and just lowering your tv electric bill really does nothing to solve the real problem which actually requires a leap in energy production technology. Worrying about your tv's carbon is like someone who hires a butler and a maid trying to save money by using off brand dish soap....

A 36" Sony CRT used around 100-125 Watts depending on how bright you had the picture. That's comparable to LCD CCFL TV's

Almost identical to the 32" Sony I measured the current on.
And by the way the model you quote is not a CCFL backlit one it's LED.
