I'm a bit of a tech dinosaur & looking to upgrade my T.V to a 50" set of which it seems to me all are still plasma. Is the electricity consumption of a 50" plasma an issue to be concerned about or not?

Depends how green you're feeling, and how much you mind paying to run your power-hungry TV - on the upside you'll need one less radiator in the house if you have the plasma on a lot
Put it this way, if you've got a 1000W surround AMP, then that is likely to be using around twice the power of a typical 50" plasma.

Today's plasma screens consumes much less power than plasma screen from just a few years back.
Most new 50 inch plasma screens consumes 200W - 250W after proper calibration. They cannot compete with LCD screens using LED, but it is not far off the traditional LCD screens.

Power consumption was the only thing that stopped me getting a plasma , and as the 42 inch plasma would of used as much power as my old 4 year old lcd, the new 40inch lcd uses a lot less . When you have a Tv on as much i do ( most of the day ) due to alternative shifts to the wife and a 2 year old son, i thought power consumption was very important.
I did try to work out how much money it would save me roughly over the 4 years of owning the lcd over the plasma and it almost pay 80% of its value which isn't bad
Next time i buy it will be for sure an LED Tv

Personally power consumption does not come into the equation when picking a TV, I simply pick the TV I prefer within my budget and not one that may save me a few quid on the leckie bill.

When and how did you make these calculations?
As already mentioned, plasma TVs of today consumes much less power than just a few years ago.
Another thing people often forget is, that power consumption of tradtional LCD TVs and plasma TVs are not directly comparable. Where a traditional LCD TV consumes power at a constant rate, the consumption of a plasma TV varies depending on how bright the picture is (consuming maximum power when the screen is white and minimum power when the screen is black). Manufacturers are obliged to state the maximum effect, but that does not give a very good idea of the actual power consumption. A plasma TV specified to 350W typically have an average effect of 200W with normal use.
Let's look at the difference listing a few examples after proper calibration:
Plasma TVs:
- Panasonic P42X20 118 W
- Panasonic P42G20 164 W
- Panasonic P50VT20 190 W
- Samsung 50B850 212 W
- LG 50PK950 225 W
LCD TVs:
- B&O BeoVision 8-40 173 W
- LG 42SL8000 103 W
- Sony 46Z5500 125 W
As it can be seen, the differences within LCD and plasma screen is larger than the difference between them. The difference is no longer that big, and you really have to watch a lot of TV for many years for this to be important.
If you like plasma and want to save power you can get a Panasonic 42X20, which is cost competitive to the LCD screens. Personally I have the same view as D.J. Picture quality comes first. Then you can always save somewhere else, e.g. taking the bike rather than the car to work.
You could of course also get a LED/LCD set. These usually consumes less than 100 W but are also usually so utterly expensive that you will never gain the extra money spent on power savings.

D.J.KRIME:Personally power consumption does not come into the equation when picking a TV, I simply pick the TV I prefer within my budget and not one that may save me a few quid on the leckie bill.
Having just received my latest electricity bill, and still choking from the sight of it, I'll definitely make sure my next telly is super eco-friendly!

In your line of work Andy surely if you're working from home watching a film/testing a system, some of that is expensable, isn't it? When I was self-employed and using my home computer to do my own accounts, the accountant claimed for a nominal sum each month for electricity, broadband, etc.
I too am wary about high energy consumption from our 42" plasma and we always make sure that its standby button is off when we're not around.

So Andy you would opt for a TV that gives a inferiour picture compared to a better TV based on its power consumption???? The power used by a properly calibrated TV is nothing compared to a amp running at a moderate volume level and thats just keeping consumption figures within AV as have you seen just how much power a fridge/freezer use and they are on 24/7!

Yes we all know things like the freezer and immersion heater uses lots of watts , but that does mean you can't think about things for the long run . People have different priority's and power consumption is one of the main things i do consider when i now buy things .
When i replaced my computer , Tv and my old faulty xbox for less power hungry appliances i've seen my bill from this year over christmas £60 less for electricity , now i don't believe i've changed anything else since then .
So for me for all future upgrades / purchases i will always consider power consumption
Its just sometimes worth considering

Andy, don't know if you saw it but I made a feedback comment on one of your tv reviews about including power consumption figures.
I was thinking that maybe it would be a good idea if all future WHF tests included the power consumption figures in the tests as this is a major consideration now for many buyers.
