See... i think they should be outlawed, they are the epitome of mans laziness at the expense of the environment. Cars... dunno, not really into em but by god they are useful. They have a very small case for existence in my book but the little red buttons... grrr.
Its just disgraceful... All we have to do is flick it off at the switch when we go to bed but no... somebody somewhere decided that that just wasnt flash enough and invented "the standby button" which everybody then copied and now you cant buy a telly which doesnt bloody have one !!! Have you seen the size of them these days as well ? Its no wonder California is having blackouts, Arnie's just switched his TV on!!
This pollution thing is no joke and tvs are everywhere, I want to know just how much of a difference it would make in energy used, if Tony Blair and his pals went "no more tellys with red buttons, they are now illegal" or words to that effect.
Its just for personal interest, im not gonna go banging on number ten about it but its a useful thread i think and i get to ask 6 thousand and something people a question, so ill probably get an answer.
Cheers

Posted: i know what people quote, but do TVs these days really use any power other than negligable amounts when in standby? On old TVs that had to warm their tubes for minutes before use, standby meant they stayed on all the time, but these days that isn't needed. If i were to design a TV i'd make the standby feature use enough electricity to run the IR reciever, and the red power LED, which amounts to virtually nothing.

Posted: there ya go, the power use in standby mode is virtually nothing:
Posted: yeh, cheers flid, im after a real world eyeview on things though, energy star is like... an optional thing for manufacturers isnt it and i bet theres no more than 50% of tv's out there that are actually energy star compliant or that will be in phase three 01.07.05.
Ive been told that the amount used in one night on standby is enough to boil two litres of water in a standard kettle. Thats a fair amount when you times it by the number of tellies and divide it by half.
Posted: so those figures show that it would take between 20 and 100 tvs on stand by to use the same power as one light bulb, how about computers that are left on? Does anybody know how much they use? How long would a person have to be away from a computer to save power by shutting it down?
about the third article down, doesnt really mean much in figures but its nothing if not suggestive is it ? whats usa today ? is it a credible thing or not ?
Posted: heh, nevermind wan, youve put that smile right back on my face, i agree what is the point?
But just in case anyones interested:
"Focus on Energy Efficiency Plays to POWI's Strengths.
According to Berkeley National Laboratory, household appliances and consumer electronics waste more than $4 billion of electricity a year while they are supposedly turned "off." By some estimates, standby or no-load power consumption accounts for about 7% of residential energy use. Standby power refers to electricity drawn by a device when it is plugged in, standing by, and ready to attain full power when needed. A printer, for example, wastes energy while it waits in standby mode until it is activated for printing. No-load power loss comes from the power drawn by an electronic product that is plugged in but not performing any actual function. Cell phone chargers continue to draw power even when they are not charging a phone, and desktop PCs that are turned off but plugged in also consume electricity.
In response to this waste, countries around the world are implementing regulations and statutes to promote energy conservation. The Energy Star program in the U.S., for instance, encourages electronics manufacturers to comply with EPA energy efficiency standards such as the one requiring that televisions and VCRs use no more than 3 watts of electricity per hour when in standby mode. Previous guidelines permitted the use of up to 30 watts of standby power. In addition, in July 2001, President Bush signed an executive order dictating that most household electronics and appliances purchased by the federal government use 1 watt or less per hour when not in use.
Power Integrations' patented EcoSmart technology has been incorporated in all its ICs since 1998, allowing highly integrated power supplies to meet the new energy-efficiency guidelines being promulgated by governments around the globe. We believe this trend will drive more and more electronics manufacturers to use POWI's ICs."
I pulled that off an Investment Banking website.
Who would have thunk it? George Bush got there before me ... I feel really stupid now.
Posted: Actually it took me a while to realize what you were talking about. My TV goes "Off" when you push the button (which just happens to be red) but I have seen entertainment systems where the TV screen kinda goes dark grey when you try to shut it "off". Some TVs do this when you shut the cable box but not the TV.
It's an interesting point but I think there are better ways to concerve energy.
Well, shall we go? Yes, let's go. [They do not move.]

Posted: I think the person needs to make coherent posts.
150 million tvs (1 for every 2 people???) probably a conservative estimate considering all tvs in residential and public places.
150 million X 30 = 4.5 billion watts = 4500 Megawatts (old tvs) 150 million X 3 = 450 Megawatts (new standards)
so the actual amount will probably be between 450 and 4500 Megawatts. (tvs only)
I used to work at a large, dirty coal power plant. It was quite large and very, very polluting and it produced a lot of pollution and 900 Megawatts. It would take between a half and 5 of those power plants to power America's tvs when they're not even on!!! That's not even considering other appliances or computers.
This doesn't seem insignificant to me, I hope somebody can explain why it makes any sense at all for appliances to use any power at all while they are not being used. I suspect that nobody can explain it though, because I don't think it makes any sense

Posted: There's an ad campaign running on Irish TV at the moment to encourage people to get off their lazy lard-asses and switch their appliances OFF at night, instead of leaving them on stand-by.
According to their information, most appliances left in stand-by mode can use up to 20% of the amount of power that they used when switched on. Also, appliances which are left on stand-by can account for up to 6% of residential energy use.
This is just darn laziness. We should try to conserve energy, however possible, at all times (like leaving the tap running on full while brushing your teeth really peeves me too)
My mind not only wanders, it sometimes leaves completely
