Big TVs costing big money on power
DYLAN THORNE - Southland | Friday, 13 February 2009
Power-hungry televisions are putting some home electricity bills through the roof.
The Southland Times has been focusing this week on energy efficiency in the home, but some modern electrical appliances need to be closely monitored.
Invercargill man Kelly Thompson has learnt that the hard way.
Mr Thompson, 70, bought a 52-inch plasma TV soon after he and wife Isla moved into a newly built house.
The home was well insulated and the windows were double glazed so he could not work out it out when his monthly power bill skyrocketed from $300 a month to a whopping $600.
"We had an electrician in and everything and he said there was nothing using power that shouldn't be."
The massive bills continued for three months until someone mentioned that leaving flat screen TVs on standby rather than turning them off at the wall could chew through power and lead to massive bills.
"I started turning the TV off at the wall when we weren't using it and the bill went right back down to $300."
Energy Efficiency and Conservation Authority production manager Terry Collins said a 52-inch plasma TV could use up to 800 watts an hour and larger TVs may use up to 1.5kW an hour.
"Some plasma TVs use more power in eight hours than four domestic fridges operating 24 hours a day," Mr Collins said.
A British study had shown consumer electronics would account for 45 per cent of domestic electricity use by 2020, up from 22 per cent now, he said.
And another reminder: Southland residents have only a few days left to be in the ballot to win a $3000 home insulation for only $600. The Times along with the Invercargill Licensing Trust and the Southland Warm Homes Trust are offering 80 of these special deals.
So fill in the coupon, bring it in to any Southland Times office and your name could be drawn out.
The Southland Warm Homes project team will also accept coupons at the Home Show at Stadium Southland this weekend.

Me too Misi .. I'll be turning it all off from now on .. all apart from the tv decoder.
If that's turned off, it takes ages to start up again, it goes through the setup system everytime.
I'm shocked too Bingbong and thank you for posting that article!!

 Well I never ! We'll have to turn the tv off at the wall in future, I absolutely never knew about this, it's a worry, I'll have to check our power bill to see if there's a difference?

well...i find it hard to believe that a 52 inche plasma uses 800 watts or 1.5kw for larger ones.lol.some heaters only use a bit over 2kw,i believe.
maybe if it IS true,then LCD is the way to go.
lets face it,if LCD's used bulk power,then they wouldnt be on laptops.jmho

The article wasn't mentioning LCD they are not Plasma's.
I think you have joined the dots......... that is why energy efficient bulbs the next generation are using LCD or LED because they are truly energy efficient many of the flat screens are energy hogs and the use compared to a that of a heat
er is accurate.
Of course many cunning sellers of TV's you may note don't display the energy use like they do with washing machines etc for a reason. Many people wouldn't reasonable associate a new TV with a energy blow out t is not in the psyche of shopping for TV's. Clearly the shifting sands of marketing unfortunately.

We have an LCD, but will experiment by turning it off at night to see if there is a difference in power usage.

LCD they are not Plasma's. yeah mate...i know...i mentioned it because many people that are after a flat screen will choose between the two. and if this story is true,then the choice wont be hard,however,i dont believe for a minute. possibly its just propaganda from the LCD manufactures/sellers my motto is "believe half what your see and nothing you hear" |

me too maire Ive given the big whaikorero here
and all switches positions were noted with care
just an extra bit of work to remember to do, but I feel its a necessary experiment

Bingbong, I want to thank you for alerting us to the bigger power bills regarding large plasmas. I went through our past power bills and compared numbers and since we bought the large tv, our bill has doubled. So every night we unplug it and will see how much difference it makes when we receive the next power bill. For this tip you deserve an exalt. Thanks again BB. |

Hey there cailz, good post, I'm going to check mine too now...I did notice a big jump over the end of winter last year but thought perhaps it was the winter bill..but it was big and that is when we bought our new TV also...when the Olympics were on. I'll be turning mine off at the wall also. Ty cailz and Bingbong |

The reason we didn't take much notice of the price hike was because we pay ours via direct debit each month.
The "smart" salesman never mentioned that this could be a problem when we bought ours last year. It really makes me angry, it's good to know all the pros and cons, we would've still bought it, but at least we would have made a more informed choice. I guess it was up to us to check it all out, but we never gave this a second thought.

Plugged in is the permanent problem. SOLUTION if is always helpful when one's insurances is paid up, is is dreadful when the moving the PLASMA BIG TV POWER GENERATOR upstairs in in to another room and the dog bumps one and it breaks, helpful with insurance for a more energy efficient model!!! I hate it when things break.

Re Lux and Punga re power "chugga lugga" LCD can be ok BUT check the back of the where is says Watts mine is an old box Sanyo 29 inch 125 watts which is good.
What are you folks would be an interesting excerise?

Punga you are mistaken and have misread the request asked re Watts not volts and I believe you are incorrect re claiming LCD do not use less power than an old box TV's. The old box use less check out the exercise.
I did a quick sweep of a store today, a 32" latest model LCD Sony Bravia was 168 Watts not to bad but they start increasing after that size and 220w is not insignificant usage better if not left on stand by.
Incidentally I asked the sales person why don't TV's display energy save/wise stickers like fridges and washing machines. He replied " TV's are not on much" I said "nor are washing machines" he said "I don't know"
I think TV's are left on a lot, in my house it is. My dog likes the TV on when I am out.
Would be interested with those who have plasmas for some other comparisons.
I believe the next generation LED will be the energy efficient.

I believe the next generation LED with be the energy efficient. nah mate.i was refering to what they draw,in amps not volts as watts are calculated by amps multiplied by volts...or something similar..leds use lots more power than lcds. ie thats why led watches were not around for long. i think watts is more about the energy that is "put out" rather than what they "draw" |

Watts punga is what is needed for this exercise as was specified in the original article if you are unable to provide then fine. *LED is the next generation of energy saver lights better than the current twister or the prong florescent *similar to incandescent traditional an course new cars come in lights come now in LED.

32" Philips LCD can't see the back of the tv but this is what it says in the manual ...
Power consumption = 150W & Standby power consumption = <2W
Looking back over the accounts, we haven't noticed any great increase in power usage since getting this tv, just the normal increase in cost from the company raising their rates.
