The True Cost of Standby Power

Luther19 writes, "How much do all of our computers and electronic devices sitting in standby mode cost us? The author of the article concludes that he could save $24.44 per year by switching out wasteful power supplies. The article also touches on a global initiative to cut down on standby power, called '1-Watt': 'The idea has been promoted by the IEA, which first developed an international 1-Watt plan back in 1999. Countries like Australia and Korea have signed on officially, while countries like the US require 1-Watt in government procurement, which will have ripple effects throughout the economy. The goal of the program is to have standby power usage fall below 1W in all products by 2010.'" It's estimated that in industrialized countries, devices on standby consume on average 4% of the power used.

    You can buy a low cost wattmeter that you plug your equipment into and simply read out the power consumption. I've found that a lot of devices in standby take almost no power. Other devices aren't so frugal. I'd like to see some real statistics on this and something like the energystar ratings you see on refrigerators put on computers.

      My old HP printer used as much power turned off as it did turned on and waiting. I took to unplugging it. I guess this arises from using an inefficient transformer and putting the power switch on the low voltage side.

      My main problem with the wattmeter gizmo is that I could not use it on the items that I guessed were using a large percentage of the power, namely dishwasher, hot water heater, and dryer. Either the items did not run on 117 VAC or they were wired directly without a plug.

  2. Wasting energy when powered down by jizziknight · · Score: 4, Interesting

    Why apply this only to standby mode? Why not apply this to devices that are completely powered down as well? I've noticed a significant reduction in power consumption when I've unplugged appliances and other electrical devices (most notably my PC) when they're not in use. Is it that difficult to implement a hard switch within the device? Understandably, we wouldn't want this for devices that are operated via remote.

    Everything I say is a lie. Except that... and that... and that, and that, and that, and that... and that.
  3. New PC PSU's might be 10-15% more efficient by WoTG · · Score: 4, Interesting

    A cheaper 80+ 250W PSU would cost a little under $40 before taxes. (I think 80+ is the new buzzword for 80% or more efficient PSUs). Older PSUs, say 2+ years, were typically in the 70% efficiency range. There are a bunch of articles at http://silentpcreview.com/ and other sites about this sort of thing.

    I ran the numbers a while ago for one of the PC's around here. The last time I ran the calculations, it costs around $50/year to power that PC for about 6 hours per day. So the break even for me is somewhere around 5-8 years! So while the power grid would get a bit of a break, financially, I wouldn't.

    I still might get a new PSU, but that's more because I have serious doubts about the quality of the power coming out of the current one (a suspicious # of hard drive deaths...) but that's a separate issue.

    For new purchases, definitely go for the more efficient PSUs... as far as "upgarding" goes... it's borderline at best, at least for me.

  4. Surge in Hybrid sales... by mollog · · Score: 4, Interesting

    Right, because look how well that worked for gasoline...

    Ok, you're trying to be sarcastic. Ask GM and Ford about this. They're both on the ropes because they tooled up for SUVs and then the price of gas went ballistic. Sales of hybrid and other higher efficiency cars have spiked and they're not going to come back down. Toyota is about to pass GM as the world's biggest, and they sell SMALL CARS. They have a sellers market. I know because I was at the dealer two days ago. The salesman was polite, but uninterested in talking. All his Camry's were gone.

    So the point is valid; jack the price of electricity and we have new incentives to save power.
