I'm all for saving energy but I keep hearing these reports that say if you leave your TV on stand-by it uses up to 70% (or something like that) of the power that it would use when its on fully.. Is this true? Its just the way my simple brain works I can't understand how having the tube off and a little red light on can use that amount of power..? surely when the screen and speakers are active etc the tv will be using a lot more power?

What about video recorders and appliances like ovens and microwaves that have clocks? Do we have to switch them off at the plug as well - meaning that we then have to reset the clocks each time?

Depends very much on the TV, some of the older sets out there are actually running most of their components at full pelt, in readiness for the button being pressed to bring them back on. More modern sets will use next to nothing as they are just powering the little LED on the front.

It is better to switch a TV (ones with CRT's anyway) off at the switch on the front, rather than just standby - quite a lot of sets only degauss when switched on from a cold start, and if they are left in standby it is quite common for them to end up with blotchy pictures.

As for videos and stuff, when in standby, they use fairly little.

Leaving your tv on standby increases the chances of it going on fire. Something to think about when you're heading for bed or leaving the house isn't it?

Yikes! It certainly is!
How often does televisually-enabled apparatus spontaneously combust?

I've always left mine on standby and never had any problems, nor do I know anyone who has. I think this was more a problem with the older TVs anyway.

I think its something to do with a power surge, its one of those things you hear warnings about but never meet anyone that its actually happened to.. still better to be safe than sorry.

Still, if you apply the same logic to any electrical household item then thngs like bedside clocks & lamps should all be turned off as well before bed, sort of defeats the object really..

perhaps the safest option is a wind up clock and perhaps a few candles instead of a lamp by your bed

Like disposable lighters ... they should never be kept in your shirt pocket.
I've never met anyone whose lighter was hit by a spark, causing it to explode, but if it did happen, your heart could get blown out of your back!

Also, I've never met anyone whose mobile phone has caused a petrol pump to explode

Bedside candles are probably quite dangerous--well, if they're lit, although I imagine even unlit ones could cause ... problems

Maybe it is an older tv problem I don't really know but how much of an effort is it really to get up off the chair and walk over to your tv when you are on your way out / to bed and turn it off fully? The odds of your tv actually catching on fire when you've left it on stand by may be 1 in a million but do you want your house to be that 1? Also re: turning off all electical applicances, most houses now have sockets with a safety switch on them so you could just switch them those for table lamps and other such appliances to off. It isn't really that much of an effort.

I think it's too much effort.

My TV's been on non-stop for about three years and is yet to explode

I'm sure tellys are built like PCs (well not literally obviously), were they can be on 24/7...wash, repeat after 3 years buy a new one.

I have two TVs - one is just the big one in the lounge which I never turn off, unless I'm going on holiday or something. It's just too annoying to go in, sit down and then realise you have to get up again to switch it on. Yes, I'm lazy. But the TV in the other room is an LCD one and apparently leaving it on standby can cause the screen to wear more quickly or something so I'm paranoid about turning it off immediately after use.

I also switch most plug sockets off when I'm not using them actually, but I dont actively make an effort to do it, it just seems to be a habit.

I only leave the tv on stand by in the day and then I switch it off at night but my Sky box is left on stand by all the time if not watching.

The old VCR I have, but no longer use had a Power Save Mode, this even shut the display off, so would only use around 1w.

Some TVs do use almost as much in standby as in full use, some still a fair amount.

Sky Digiboxes and cable boxes use virtually the same power when on and standby, as they aren't really in standby just not sending a picture to the TV.

We always did switch the microwave off, not bothered about the clock, don't need to waste electricity when we have a wall clock.

Recently we have started to switch everything off at the mains, and not use standby, as these few watts here and there add up, so why waste money for nothing, and why pollute the environment when we don't have to.

The DVD/HDD recorder and DVD recorders update their time when switched on so we don't have to worry there, the cable, satellite and Freeview boxes update their clocks too.

We now have all devices on their own switch, so when we aren't using cable we switch that off, when not using satellite switch that off, when not using Freeview switch that off and so on.

When I worked several years ago for one company we were forever getting Amstrad TVs in that whilst on standby had caught fire and melted the casing.

Items catching fire might only be a tiny percentage, but by switching them off completely you know they aren't going to catch fire due to electrical problems with them.

If you could all switch things off, we could reduce the need for electricity.

Good for you. I do the same as far as I can.

In terms of power usage, the old CRT screens will drain the most power when ON or in Standby. Its not just the little red LED light that is using power in standby - if it were, it would not be a problem. So do yourself (and the planet) a favour, and turn them off fully when your not going to be using them. You will save money and help reduce the "green house effect" on the planet. LCD tv's use around 50% less power if the LCD is about the same size as the CRT - so again if you replace an ancient CRT with a similar sized LCD, you should save a bit more money (and the planet). If you have (for example), 3 tv's in the house, the effect would be even greater when you change them.

We aren't saying that everyones PC will go up in flames, but you will increase the risk of it going up in flames if you leave it on.

The same way as when you cross the road there is a chance you might get run over, yet if you don't go outside then the chance of getting run over are virtually nil.

Yes but by going by this method of being sooooooo ultra safe that you don't do anything because it might end up in flames is soooo ultra conservative that there is just no point to having the equipment in the first place.

My dad makes sure everything is switched off when it's not in use for longer than a minute! The TV must NEVER be left on standby, and most things have to be switched off at the plug at night or if we're out. But surely it'll use more energy keeping on turning the TV on and off the main power?

He says he's like this because he was a fireman, so saw peoples houses go up in smoke every day.

My smoke detectors are all connected to the mains and are on all day and night.

So should I turn them off when I'm out, you never know they might set the house on fire.

The point is when it's on you are usually there watching/listening/using so if it does go up in flames you can do something, if you leave it on standby and go to bed or go out the fire could have easily spread.

Even if you don't want to do it for the fire risk, do it for the environment and your pocket.

My Samsung can't be turned "off", properly, without unplugging it. Your manual should have power consumption info - I guarantee though, on standby it will barely use any power.

Unless they're lying, of course.
