Mrs. Murdoch saw an expert of some kind assert this on Ellen this week. This sounds rather hard to swallow. Never mind the tube addicts who never shut the damn thing off. I know appliances can suck up a lot of juice when turned off, but 75% for a TV?
It depends on what the 75% means. If it is 75% of the total energy used over say a week I could see that happening if you only watch a little TV. Numbers that follow are pulled out of my ass. Say your TV uses 4 Watts when off. This runs the remote control electronics. And When on it uses 300 Watts. If you watch 44 minutes of TV a week then 75% of the power is when the TV is off. You can play around with the numbers but it sounds total bogus.
On the other hand it could mean that the TV uses 225 Watts when off on 300 when on. This is completely wrong.
For the record TVs with the energy star logo must use less than 1 watt when off. Most TVs sold in the last 10 years meet this requirement.
No, that’s completely ridiculous. TV standby power draw varies considerably between sets, so assering a single figure is just wrong regardless. In any case, typical TV sets vary between 5 and 20 watts or so for standby draw; typically, sets use between 70 and 90 watts, full power. Clearly, this is nowhere near 75%.
That’s funny - I just read (like, an hour ago) a blurb in a magazine that suggested plugging all appliances into a power strip at home, and then turning the power strip off when the appliances were not in use. Thus saving $$$ in electricity that the appliances normally use while turned off.
I thought it sounded like BS, but I didn’t realize that TV’s can use that much power in the off position. But is this true for other appliances? For example - are my lamp, toaster, iron and computer printer using power while they are turned off?
Only the printer, unless the power switch is really in the off position. Any device that has a “standby” mode must use power so that it can respond to intermittent turn on commands. If your iron stayed a little hot all the time, or has a lamp that is on when it is plugged in, then it would consume power.
Its not completely bullshit (I actually do this with some of my electronic equipment), but your lamp, toaster and iron definitely don’t draw any power (what would they be doing on standby…unless you have one of those new toasters that you can set to make you toast on a timer I guess). The computer and printer definitely draw though…and your microwave and TV too. Anything that runs in a standby mode is going to draw at least some power even when its off.
Since this is GQ and all, thought I’d toss in this link about standby power devices.
Maybe I was wrong…this seems to be saying that even things like toasters and such use a trickle of power all the time…if they are plugged in. :smack: I didn’t know that…I usually only turn off (by use of power strips) my main electronics and TV.
Toasters? No, not unless they have a clock or other circuitry that must be powered at all times. Generally, simple motorized or heating-element appliances which don’t have any sort of timers or microcontrollers and the like have zero standby power. Things like toasters, vacuum cleaners, hair dryers and such.
