Someone needs to find the actual citation, and figure out what the real
impact is. I suspect this is another one of the claims akin to the idea that weed whackers and lawn mowers are contributing a significant percentage of our total pollution. I'm just not buying it. There are so many other things that desperately need our attention. It really galls me when junk science and distorted statistics is used to confuse people into promoting some extremist agenda. |

The real question is what is meant by mrbog's 5 percent. Is it total power used or wasted power? If the load has a real reason for being powered at all times, then the power consumed by it isn't wasted, and the losses in the wall-wart shouldn't be considered as being wasted either because they would otherwise be dissipated by a power supply built into the load, assuming comparable efficiencies. If the load is disconnected or turned off and the wall-wart is left plugged into the wall, then its power dissipation should drop to the order of a watt or so, unless the device is poorly designed. I suspect that the 5 percent figure refers to the always on case, but has been subjected to a little journalistic sensationalism. The trouble is, mains-powered equipment tends to be turned off when not in use. Wall-warts tend to be left permanently on. They tend to be warm. That's wasted power. I don't have figures to hand. But I recollect a report telling how much you saved over a year by turning your TV off, not leaving it on standby. Wall-warts were also mentioned. The saving was not trivial. |

Look, if you're talking about energy waste in the USA, why not add a little perspective? Try convincing just one person you know to give up their SUV and buy a regular sedan. The energy savings on that alone would probably be enough to power 1000 "wall warts" for ten years. Ride a bicycle or take public transport to work once a week:- save more energy and money than eliminating every "wall wart" in your house. |

I don't particularly mind the warmth. Though the room with my computers and music gear rarely needs heating turned on :-) I was just mentioning it as an indication of wasted power. |

Oh, I've given up on the USA :-) But some less arrogant nations still believe small savings add up, and are worthwhile. |

Looking at the Radio Shack website, PRO35A's are on sale for $19.99 once again right now. I notice that website/phone sales show out of stock, so you'd have to check stores, but you should try them anyway. Looks like the sale is thru the 24th. |

writes (responding to mrbog):
...You, in your irrational ranting, even failed to notice an error I made in the calculation: the figure quoted from the DOE is 3,858,452,253 megawatts/year. That's not 4 trillion watts or 4 x 10^12 Watts per year, that's 4,000 TRILLION Watts or 4 x 10^15 Watts per year. It makes your assertion so toally absurd because it raises the number of wallwarts by a factor of 1000.... Unfortunately, I think you made a second error, comparing wallwart watts with the yearly production quantity. It's not my area of expertise, but I'd guess a 2-watt wallwart uses electricty at a watthours rate, or 2 watts per hour. That works out to 365 days x 24 hours x 2 watts = 17,520 watts/year or, generously 2x10^4 per wallwart. That would have a net effect of reducing your original results by a factor of 10. (I.e. only 12.5 duplex outlets full of wallwarts per room, assuming every wallwart in the country is idle all the time.) -Dave |

You're not going to try to prove you're not a commie homo, and I'm not going to try and prove I'm not a troll. So, commie homo, It's still evidently not really true. You've already been given all the information you need to solve your problem, several times over. You don't need batteries or wallwarts to do so, so even if you're set against those, that's just not relevant. Buying new headphones is not a solution. Hiring an electrician is not a solution. You pretend you've solved me problem if it makes you feel better. It seems you don't really want a reasonable solution, either because it would work toward bringing this thread to a close; or because it's your excuse for your going on about your pet wallwart threat and your pet soundcard peeve.

I like padded grapefruit style headphones. Headphones I could use just find in 1999. Headphones that even the 2004 models won't be loud enough for modern soundcards. Oh but I suppose all that doesn't matter, it's just the troll trying to get you to respond. |

Makes you think, eh? About the orifice they used for that number, sure. The math is simple: count up the yearly usage of various bits of military hardware in hours, multiply by the average fuel consumption per hour, and compare with the same figures for automobiles. Fighter airplanes and tanks are counted in the thousands, while there are more than a hundred million private cars in America. Even if the khaki gear were used at the same rate as commuters (which they're not - that stuff needs maintenance), the fuel consumption isn't 10,000 times greater per hour than even a Prius. I daresay you'll find that decimal point in the alleged 60% moves some places to the left. Francois. |

So what you're sayin is that only a mere 6% of the TOTAL FUEL CONSUMPTION IN THE USA is going to military use? That's still a ****load of dollars. |

I'd be surprised if military consumption were even at 6% of total. That's still a ****load of dollars. You could, for another data point, look at the Pentagon budget to see how much they do spend to gas up. I don't recall it being a particularly large line item. Francois. |

I didn't say 5% of all fuel, I said 5% of all power. And by the way, "permanently powered" is always the case with wallwarts. That's the point. |

I have at least a dozen wallwarts on switched outlets, warts that are only on when running that system; everything from printers to netwirk hubs to reverbs to zip drives. My computers are all on switched outlets and thus draw nothing when not in use. ...thus, as others previously noted, it can be done. Ron Capik -- Yea ok, I'll grant you that I'm technically incorrect to say "always". But the context of what we're talking about is the USA's consumption of power. And, inarguably, people like you are the minority. Most americans aren't plugging their wallwarts into power strips and turning them off. So you get to criticize me for saying "all" when I should have said "all but one half percent". It's not much of a point. I could say "all americans wants to be happy" and you can say "no, some americans are masochists, so they don't ALL want to be happy". And I say "ok, yes, I'm wrong, you're right. I guess you win then." |

[...] Ahem. Fuel is used for manufacturing things, and for running establishments, not just for keeping vehicles moving. Look at your industrial base for serious fuel consumption, and at all those military bases around the world, and the US Navy at sea, etc etc etc. Sure the industrial base eats fuel, but follow the money: DoD procurement is maybe $50 billion a year TOPS. Consumer consumption, even admitting imports, is about two orders of magnitude higher. Assuming that energy use is a reasonably constant proportion of production dollars, consumer production still consumes far more energy than military. And as far as bases/warships go, the previous argument still holds: 200,000,000 people drive almost every day in the Excited Snakes. Beside that a few hundred warships are (ahem) a drop in the bucket. BTW, even at worst case figures of ten per household, permanently powered, it's unlikely that wall wart wastage exceeds 0.0005% of total US fuel consumption. I'd drop a few of those zeros, but agree it's less than 1%. Continually-on appliances (microwave clocks, instant-on TVs, etc) probably take far more. Cheers, Francois. |
