    In the last 6 months I have gone to a number of detailed scientific talks on the effects of global warning (I am a space chemist) and each scares me more than the last. Currently, AFAIK, all DVR's use 40-50 W 24/7. For most of us, I suspect 3/4 or more of this time, an energy savings mode would be desirable. Taking these numbers that is about 24 kW hour per user per month wasted (about $5 per month in MA). As DVR's are now becoming mainstream, that is an appalling amount of power nationally.

    Therefore, I strongly urge that an energy savings mode be added.

    Al Gore, ladies and gentlemen!

    What sort of world do we live in when people's #1 reason for energy savings isn't their electric bill?

    Bottom line... I would love an energy savings mode... I could use the extra dough to put high octane leaded fuel into my muscle car.... Those tri-power carbs really suck down the gas!

    Has anyone does any hard core research on the HR20 to see how much power it truely draws on a regular basis?

    I know a lot of people did on the TiVo platform...

    IMHO what's alarming is the time wasted worrying about GW. My DVR energy usage is in line with my other electronic components. ;)

    Might I suggest that you could save a lot of energy by turning off your computer.

    I have a kill a watt meter, I'll stick it on over night and see what happens.

    My computer has an energy savings mode that reduces power from 70 W to abuot 8W. I do turn it off when not in use for long periods. I have added relays to most home theater equipment.

    There are 3 good reasons to worry about how much electricity you use:
    1) cost
    2) reliance on mid east oil and therefore terrorism
    3) saving the planet for younger generations

    Al Gore is only a messenger, global warming is real and everything I hear from researchers (not politicians or news) in the field is extremely worrisome.

    It would be so simple to do, our electricy is expensive here too. Why add the extra heat to the A/C load? We save where we can but don't go to extremes.

    I agree 100%. Having a power saving mode on DVR's would be a good idea. I would use it if it was available. I am not a poster child for saving power and helping prevent global warming. My old 55 chevy pickup gets poor mileage. I built it before gas was over $1.50 a gal. I have plans to build some kind of electric or hybrid electric car or truck to replace it. I am going to change all my lighting to fluorescent as my old bulbs go in my home. Looks like it is going to be the law in Connecticut one day anyhow. These things should make up for my DVR not having a power saving mode for now.:D

    Outside...
    How exactly would this "Power Saving" mode work? Is it going to go in and out of Power Saver mode as it needs to record things, or would you have to do this manually yourself (Pretty much defeating the purpose of a DVR for me)?

    Again...

    Does anyone have accurate data on how much the HR20 draws?

    I can tell you that with an eSATA drive (Seagate 500) that pulls 3.0A max and the HR20 on my UPC, it's only drawing 39 Watts - from what the APC is telling me. It's hard to get a correct AMP draw on it with my meter. I'll try it later when some of the important stuff isn't recording.

    Doing the conversion of Watts to Amps by the equation Amps = Watts/Volts

    39/120 = .325 A with two shows being recorded.

    Someone might want to check my math on that. ;)

    Basically, the lamp in the corner of your room is drawing almost twice as much energy (providing it's a 60w bulb) as you're trying to read the remote to power it down to save money. :D

    I worked for years doing desktop support, and the power saving options were a constant problem for us. Machines not coming back from standby, getting hung on shutdown and startup, etc. Overall, it did wonders for the energy savings of the company, but for the small percentage of people who's PCs were always on the fritz, it stunk. In my opinion, there are still more important things for the HR20 developers to work on than a power saving mode. We don't need any new features that would likely increase the potential for failures. If it's something that can be seamlessly worked into future models, than I'm all for it. And honestly, there are far more "appalling" wastes of electricity out there in most homes.

    Most of the energy draw, I'm fairly certain is energizing the LNBs. Since the HR20 has to continue to keep current with Guide info, messages (maybe not the human readable ones, but authorization and software related), etc. I don't think any receiver/switch/dish combo can be easily reduced by much.

    I'm bettin' there are bigger fish to fry. (But be carefull--some ways to save on your electric bill cost more in overall energy from birth to grave of the device than the old fashioned devices...)

    Cheers,
    Tom

    That's the part I'm afraid of testing. Changing channels, with eSATA, without... I'm sure there would be spikes depending on usage. Unless you pounded the channel button I don't think you're going to get much draw.

    I would imagine, majority of users USE the DVR. The DVR turns the channel once to record and then stays there for 30 minute or 1 hour or more depending on the show. Then you are just going to the HDD to watch the show and aren't doing much channel changing then either. I don't think power consumption is an issue at all here and like Tom stated, there are FAR better ways within your household to save costs.

    We have switched over to flourescent lamps, all through the house. If the HR20 draws 40 watts @ .10 cents a KWH = about .10 cents a day. Not alot, but if it were to go into standby might save a buck or two. With the way oil is going, electricity is going to go alot higher, fairly soon I'm affraid. We have 3 DVR's.

    Why not just put the unit in standby when not in use?

    I'd be curious to know what it draws when on vs. standby. There should be a difference, right?
