    Recheck your'e math:

    12 hrs day x 25 watts = 9 kwh's

    9 kwh x 25 cents = $2.25 month or $27.00 per year

    Well worth the switch :)

    It was late when I posted that, but unless ThomasM has an extraneous period in his post, he posted that the electricity rate was .25 cents per kwh (notice the leading period - that is $0.0025). ThomasM also posted that the power consumption in standby mode is 23 watts.

    12 hours/day x 23 watts / 1000 watts/kilowatt = 0.276 kwh/day

    0.276 kwh/day * 0.25 cents/kilowatt hour = 0.069 cents/day

    0.069 cents/day / 100 cents/dollar = 0.00069 dollars/day.

    $2.69 / $.00069/day = 3898.55 days

    At that rate, if I bought the switch today, it would pay for itself on November 18, 2022.

    If ThomasM meant to post that his electricity rate was $0.25 per kwh, then the cost per day of running the switch is $0.069 (almost seven cents per day). At that rate, it will only take 39 days to pay for the switch, but I was only going by what was in his post.

    It would be nice to use your common sense before taking meaningless number and produce meaningless result ;).

    If his kwh rate is really $.0025, I want that company. Mine is 0.0587, and that's lower than the normal electric company rate.

    .25 cents is a very common error made when 25 cents or $.25 is meant. If it's 25 cents per kwh, I don't want his company :)

    Well explained. If electricity were in fact that cheap anywhere, you'd see a bunch of aluminum plants moving in.....:sure:

    this may be another big brother deal, the feature is to make the HD equipment energy star complaint. I looked at the directv blog and thats what I gather from what's there. I have 4 of the hr something and I would guess that by the time the 2 watts over the entire directv system adds up to a sizable number.

    Yes, but more effective is turning off the set when not watching it! Rather than letting hours pass by.
    And the real savings comes with turning of the TV itself, not the DVR.

    Average price for electricity is about 10 cents a kilowatt hour. And thanks to green mandates imposed by misguided pols, some people pay as much as 24 cents a kilowatt hour.

    -------------------
    http://gigaom.com/video/set-top-box-energy-hog/

    NRDC tested a number of set-top boxes and DVRs from multiple service providers, and the data wasn’t good. According to the study, the most efficient DVRs tested came from AT&T, and drew about 18 watts when on and 12 watts while in a light sleep mode. But compare that to the Apple TV, which draws just 3 watts of power when on, and less than 1 watt while in sleep mode. Or even to European DVRs, which typically draw 10 watts or less when powered on.
    -------------------

    Question for the many brilliant engineers that contribute to this community. How is it that European DVRs consume less power than the ones in the US? Is the user experience that much worse?

    Because they don't mind stop HDD in these DVRs.

    So we are talking about ~$25 /year savings.
    Let's talk real savings. Turn your refrigerator off. :)

    The problem with California, if you can save just a little bit of electricity, you can sometimes save huge amounts of money. They charge us so much per kw up to a certain amount of usage, then they charge you so much per for the next teir, and so much for the next teir, and so much for the next teir. So if you are only into say the fourth teir by a couple kw hours, that can still be a massive increase in your bill. If you can drop usage just a little then it will save you lots of money. This is why it'd be nice if we had the option of having drives spin down.

    What I'd love to see is a dvr that had 100 gigs of flash memory of some sort, that used very little power. Let the unit keep the guide data, pushed movies, and buffers on that, and then only spin the hard drive when you are actually recording or watching something you set up to be recorded. People who didn't record anything over a weekend, and watched nothing but say live sports on a Saturday and Sunday could sometimes save a lot of power and money.

    The best solution to all this is everyone put solar panels on their roofs and tell the power companies to go shove their rates where the sun don't shine so we can use as much power as we want and regulate as we please. :)

    On the directv remote there is an off button when I stop watching tv I push it and that turns of both. I assume that the sleep mode that the dvr stages into after 4 hours is only after the off button is pushed. As far as the set itself that goes into a sleep that pulls just a few watts maybe 2 or 3. I replaced every set in the house this year with led/lcd's and also changed out all of the hi hour use lighting with led's. If we are going to get picky about power use on the entertainment systems what about the power transformers used in the SMW/DECA systems they are on 24/7 and I am sure pull 5 watts at lest. Now take a look at that over weight surround receiver in the main TV room mine pulls 5 amps not watts and I just don't happen to remember OHM's law but when its on its working. and what about the powered sub woofer? Think I'll keep my refrigerator on to.

    Some might think there is more than one, but I did check PG&E's rates:

    [table]Baseline| $0.12845/KWh | 100%
    The next 30% | $0.14602 | 136%
    Then up to 200% | $0.29518 | 229.8%
    After that | $0.33518 | 260.9% [/table]

    That's what almost all of us do, I am pretty sure!
    But my assumption is that the sleep mode isn't activated at all when the DVR or receiver is in standby.

    If i'm not recording anything over night i just shutoff power to my dvr. Don't ask me how much that saves.

    Uh, the whole point of the sleep mode is if you forget to turn the unit off, it will d it for you after no button on the remote has been pushed for four hours.

    Turning it off wont stop it from recording. All it does is deactivate the video outputs and lets the receiver know it can do housecleaning without worrying about using to many resources to slow the unit down for a user.
