How much an hour to run a 42" plasma TV?

Not always the case Cardew. We all waste massive amounts of power by leaving appliances on standby. The best thing for the pocket and the environment is to switch off at the wall. The BBC website had an article on this last year http://news.bbc.co.uk/1/hi/sci/tech/4620350.stm and there are undoubtedly many more to be found by Googling.

Welcome to the Forum.

A couple of points:

Firstly ‘Normally’ means exactly what is says – and that doesn’t preclude ‘not always’!

Secondly as I said in the post above:

This is normally the cue to get lectures on:

• Any saving is worth having.
• You are personally responsible for global climate change - if you leave your TV on standby.

The OP asked for factual information. The facts are exactly as I stated “most TVs use very little power on standby” and for virtually all TVs manufactured in the last 10 years the cost is measured in pence per year.

Obviously if there are xx Million TVs left on Standby, even consuming a Watt or so, that is a large amount of power; and nobody is advocating that you leave the sets on standby.

The point is to get things in perspective. If you read though these forums you will find that lots of people simply have swallowed the ‘hype’ about huge standby consumption of TVs and think all they have to do to drastically reduce their bills is switch off standby TVs. In doing this they ignore far more wasteful practices – boiling full kettles – not using low energy bulbs etc etc.

Counter lecture finished!

It costs about 70p per annum for each watt. The most recent TV I bought (a 17" LCD with integrated Freeview) consumes 5W in standby.

The cost of leaving all the TV's in my house on standby would certainly be measured in pounds not pence.

Hi,
White on blue is not the easiest of combinations to read.
Try green, best is if you can swap bacground to green and use yellow type.
Also if you can use Comic Sans font.

Nice combination, comic blue on white. Better bold.White on white is good, too.

:j I`m definately switching things off in future. I`m so good with my recycling, and not wasting water, so will promise to do my bit towards not wasting energy! Do you think this balances out? I`m wasting energy later by using the TV to watch Casualty, but saving my energy,on the settee with my feet up! Only joking!!

Well, a 40" Sony Bravia only consumes 0.5W in standby. Cardew is "normally" more accurate than most when it comes to power consumption.
As for your 17" consuming 5W, doesn't sound like a model that appeals to me. I notice you never mentioned the make so others could avoid.

70p a Watt if left on standby 24/7 365 days a year - some of us use the set though.

All the major manufacturers signed up some while ago to have standby consumtion under 1 Watt and many are considerably less than a Watt. A bod in Toshiba said 0.1 Watts was an achievable aim.

I have 3 TVs a 6 year old 32" Sony CRT consumes 0.6Watt, A 28" Panasonic CRT, also 6 years old, consumes 0.9 Watt and a newish 32" LCD is well under 1 Watt.

If your 17" LCD does take 5 Watts that is very poor and I suggest atypical, but still measured in pence per year if left on 24/7 and not used; albeit 350 pence!!!

I must keep making the point that I am not advocating leaving sets on standby, but this emphasis on a fairly minor issue detracts from far more achievable and greater savings.

My inefficient TV is made by Humax. The 5W consumption in standby is taken from the specifications in the instruction book, I have not been able to test it.

Consumption in standby was not something I considered before buying, because I'm in the habit of turning all my TV's off at the socket when not in use. But well done to any manufacturer who's got it down to a fraction of 1W.

I bought an interesting device from Maplins that monitors electricity usage - very, very useful.......

I would willingly switch my TV and associated attachments off every night but I have been told that the SKY box updates its software, sometimes during the night. Our Humax Freeview box will apparently blow a gasket if it is interrupted whilst updating its software - and there is no way to tell when it is doing so. What does everyone else do?
I did have a problem with the SKY box when we used to turn it off and it was the devil's own job to reset. It took two of us as it was impossible to follow the instructions on the phone while concurrently pushing two buttons more than a hand span apart.:rolleyes:
