50" Plasma Screen TV Electricity Costs - Help!

amyparr

Hi guys,

I'm having a long-running debate with my Dad about saving money on our electricity bills, and I was wondering if anyone out there could help me?

My Dad, like most Dads, has gone on at me for years about leaving lights on in the house, particularly at night, and bemoans the added cost to his bills that i cause him because I don't always turn them off. Pretty common I imagine.

However, my Dad recently went out and bought a 50" plasma screen TV which he leaves on ALL night and ALL day unless someone else switches it off!! This has been going on for a few months, but he still deludedly believes that the cause of his massive electricity bill is me leaving a couple of lights on at night. Not his massive TV, air conditioning unit, or fridges, naturally.

What I was wondering was, does anybody know the average cost of running such a huge TV, and by comparison what the cost of leaving a light on would be? I would love to tell him!

Oh the joys of living with your parents, this is what it has reduced me to!

Doing a quick google search comes up with about 400w which sounds quite a lot so I'm not sure if this is right, but I think plasma's use more than LCDs.

So if left on 24 hours a day would use 9.6kWh a day 67.2kWh a week.

So it was on say 12 hours a day for a week it would be half that 33.6kWh

Electricity prices ranging from 8-15p per kWh would cost £2.70-£5.00 a week

£140-£262 a year on 12 hours a day.

This sound about right to anyone else?

Lights depend on what wattage they are, its probably not likely to be more than 100w which for the same 12 hours a day for a year would equal £35-£65 per bulb. If it is energy saving maybe more like £4-£8 a year 12 hours a day per bulb.

When you say 'leaves it on' I assume you mean leaves it on standby when he is not watching it? Not the screen showing the TV picture?

The power consumption of Plasma TV sets varies but tend to have pretty high consumption when switched on(on a Pioneer is about 300 watts - say 2.5p an hour) On standby it is very low 0.5 watts - say 40 p a year if left on 24/7.
A 100 watt light left on will use about 0.8p an hour.

Solutions - move out - or pay the bills - or switch lights out!!!



Somebody on this forum said a little while ago - when I visit my children who have now left home I go around the house switching on all of their lights because I thought that's what they liked and i was doing them a favour.

If you want to make a point THIS will give you the evidence you need.

However, if you want to save money, keep quiet and take a bit of stick for leaving lights on, it's a lot cheaper than getting your own place.

Maplin are selling a similar device for £13 - they have been available for a fiver from Aldi/Netto.

One firm has climbed on the 'green waggon'(save the earth by using our device!) and is charging £79 for the same - mind you it is made in green plastic.

Thanks!

Afraid I don't mean standby - he actually leaves the picture on, even when he's asleep! Crazy I know!

Haha I would contribute but my Dad refuses as he says he doesnt need the money, he just moans about it out of principle!

its more the air con unit, i looked at one the other day that was 1800w

Incidentally plasma screens have a very short life span. 5000 hrs ring a bell. Being left on for 24 hrs aday will reduce that to what? About 200 days? Its worth turning them off! Obviously the 5000 hrs, is how long its guaranteed for, it may last a lot longer than that!
