    I would love to see TiVo go green with a software update.

    5 TiVos in my house, an average of far less than 10 total hours recorded per day.
    If they all slept when not recording that would equal a savings of over $200 per year.

    An easy "close" estimate you can use is $1/year/watt run 24x7 so a 40watt TiVo averages about $40/year (plus or minus as your local electrical costs vary from a 10cent per kwh average cost)

    In Hartford CT the cost is over $0.18/KWH so each watt cost $1.58/year. My series 3 uses 51 watts (with a 1 Tb drive WD green) so that over $80/year. I have the unit on a timer that turns it off at 4am and back on at 4PM, never had any problem now that the 30 sec skip does not go away.

    TIVO does need to get on the bandwagon for energy conservation. Perhaps not in their present models but future models.

    The easiest way to go would be to have the OS in flash and a hard drive for recording. With this setup, drives could be spun down and minimal power used. As well, TIVO out to consider going to "slots" for 7200rpm laptop drives. One would purchase the unit driveless or with a drive. Then select "approved" drives to "build" their system. There should be TWO slots available to really make this of value. Laptop drives are reaching 500 gigs in the 5400rpm and we can expect soon 7200rpm laptop drives at near that capacity soon. Laptop drives consume less energy than 3.5" drives. TIVO in turn would reduce manufacturing down to 1 model as it is now "adaptable" and can be put in standby mode with minimal power requirements during non channel or record use.

    Green isn't just about less power but about not having to throw entire systems away when a part fails. This is often the case in non-modular systems like the TIVO (yes one can send for repair or "swap" but the notion still holds true).

    Another waste of electricity is having to run a windows PC running Tivo Desktop to let tivo view your photos or play your music. This typically uses >150 watts.

    Tivo should support upnp as a upnp client. There are many low power NAS devices that will stream music and photos via upnp while using less than 40 watts.

    Can someone measure the power draw of a Tivo with the hard drive unplugged?

    I recently set up a Windows Home Server box using an old Compaq AMD system. The dual core processor is overkill for the server, but I could shove four SATA drives in the case. I bought the OS from Newegg.

    Using the AMD power save settings on the CPU and spinning down the drives gets me to ~40 watts idle power, and during backups or transfers, it pulls about 100 watts. There's an add-in service for WHS that is a TiVo server. The WHS shows up in my NPL and it can also handle photos and music.
