Power consumption
I have a Sony Receiver STR- DE675 rated at 220W power
consumption. I have my PC's sound connected to one of the receiver's inputs. I would appreciate if someone could estimate how much power my receiver is drawing when it is on and no sound is being generated. |

Your guess (between 1 and 200W) will be nearly as good as anyone elses, but probably closer to 10-30W. I forgot to add that I'm using Cambridge Soundworks M50 speakers if that is relevant. Not really. MrT. |

I would appreciate if someone could estimate how much power my receiver is drawing when it is on and no sound is being generated. Probably in the 10 to 15 watt range. More recent models by many manufacturers are designed to draw less in Standby mode, but when turned on, and at idle there are losses which, in full sized receivers, cannot be reduced too much while still using mostly conventional transformer power supplies and bipolar transistor output stages, which the market and economics still demand for the most part.

I would appreciate if someone could estimate how much power my receiver is drawing when it is on and no sound is being generated. If you want a wild guess you could use 10-20W. Note that it may even draw power when it is turned "OFF". This has nothing to do with what kind of source is connected (PC or otherwise), and also nothing to do with the speakers (unless they have their own power cords). As Mr. Krueger suggested, it is pretty cheap to just get yourself a "Kill-a-Watt" meter and measure it directly. They are handy for other things around the house as well. Particularly if you are trying to reduce your power consumption. http://www.amazon.com/P3-Internation.../dp/B00009MDBU Significant numbers of modern electronic equipment never really turn "off", rather they go into some sort of standby mode and turn off all the lights to make it look like nobody's home. This is particularly the case with equpment that operates from "wall-wart" power (transformers or switching supplies in the plug, or in a "power brick" inline with the mains cord) because that part never gets switched off. This is one of the issues that the "green" movement is going after. There are already both industry and public ads for "greener" power supplies that draw minimal (or no) power when turned "off". This web page claims... "The U.S. Department of Energy tells us that not only do appliances continue to draw electricity while the products are turned off, but in the average home nearly 75% of all electricty used to power electronics is consumed by products that are switched off." http://www.terrapass.com/blog/posts/...tricity-vampir With one side of his mouth Obama said that he wouldn't "increase taxes" on the middle-class, but with the other side, he _promised_ us that energy costs would "skyrocket" (his term, IIRC). I have great confidence that he will faithfully deliver on THAT promise. |

Wrong way to look at it. Certainly insignificant on an individual level; not so on a global one. That should be "keep them unplugged all year and save ourselves from having to make many more megawatts of electricity".

Probably cleaning the coils will make up for any wall supplies. Refridgerators still are dumb. The defrost cycle should not occur when your using it. You should be able to set the time of day for that to occur. I have measured the drops in temps of the freezer and fridge with a recorder, and thay are not trivial. This is without opening the doors. greg |

No argument, but still only a *MINUTE* fraction of total energy consumption! Your citation simply doesn't support your theory. It's just a red herring for the technically illiterate. They measured the power consumed by cable and satellite boxes and found that they consume nearly as much power when switched off as when turned on; switching from "on" to "off" with a remote control seemed to do nothing more than switch a light from green to red in some cases. No argument there either, but still only a *MINUTE* fraction of total energy consumption. Turn your air conditioner off for one day, and you can run your cable box for a year! Maybe you better learn just how much these items consume in ANY mode, compared to an electric stove, refridgerator, air conditioner, electric heater etc. And that's not even counting the BIG power useage, *INDUSTRY*. A typical aluminium smelter uses more electricity than all the average domestic users combined for an average city, regardless of what light globes they use, and whether they have NO standby devices at all. In any case the REAL problem is too many people, until someone proposes to REDUCE global population, they are simply talking out of their ass! MrT. |

I *know* that doesn't include industrial uses of electricity, and I don't know what the proportion domestic usage is to industrial usage; I do know it's still a significant fraction of total electricity usage, not "minute". IF YOU think it's significant, then you must have some idea of what it *really* is, and some idea of what YOU think is significant? (based on more than pulling figures from your ass, or misquoting someone else who pulled them from their ass) Add to that the fact that most of our (U.S.) electricity comes from burning fossil fuel (coal, oil or natural gas), one can state with some confidence that the total contribution to global climate change from "vampire power" devices is something on the order of 1 to 2 percent. No you cant! Sure it's greater than zero, that's all you can really say without any *facts* to back it up. Not the primary cause of the problem, but not insignificant either. And NOT 5-10% either! "Significant" is obviously open to any interpretation. You are welcome to yours, and welcome to act as you see fit. I suggest reducing your REAL power usage before worrying so much about the the last 1%!!!!! What I object to is taxes and trading schemes which do nothing except increase prices to consumers and reduce our standard of living, whilst we merrily increase the global population and make the problem worse. Our government *encourages* overpopulation by paying baby bonuses, and importing more immigrants than our local population growth every year. The upshot is we have national water shortages, and a plan for huge increases in energy costs. MrT. |

Should save the planet for another couple of days anyway I guess. :-) I don't think so. It's a real energy sink; researchers estimate phantom power as 5 to 10% of household energy usage. Those researchers - what kindy were they from ? Clearly hadn't learned basic arithmetic yet.... Their idea of a household doesn't have lights, a fridge, HVAC, or hot water. |

Or an electric stove, washing machine, and dryer. Hmm, perhaps something like a dorm room with maybe a mini-fridge and hotplate? With a lot of electronic gadgets of course. Then you might get into the 5-10% usage range. Jerry |

"David Nebenzahl" wrote in message s.com... LBNL [Lawrence Berkeley Nat'l Lab.] calculated that videocassette recorders (VCRs) consumed more electricity over the course of a year in standby mode than while actively recording or playing. No argument, but still only a *MINUTE* fraction of total energy consumption! Your citation simply doesn't support your theory. 5-10% of household consumption *minute*???? It IS minute and it's NOT 5-10% of *TOTAL* electricity consumption. And a *totally* insignificant proportion of total GHGE which is caused by far more than electricity usage. But do feel free to provide PROOF of exactly what proportion of *TOTAL* GHGE is caused by standby power consumption, I'm sure lots of people would be very interested in your *scientific* research. **I'm disputing your points. The big problems are water heating, space heating and cooling, pool filters and the other stuff. FWIW: I measured my STB in standby. 20 Watts! 22 Watts when operating. I just purchased a new PVR from the same manufacturer. Fortunately, they've learned their lessons. It consumes 0.6 Watts in standby. IMO, mandatory low power consumption in standby is a very important step. -- Trevor Wilson www.rageaudio.com.au |
