TiVo Energy Usage (How Much Does It Cost To Run A TiVo)?

Update 01/26/06 @ 8:13 PM: According to the Series2 install guide, a Series 2 TiVo uses 40 watts. Using this information, it costs ~ $14.38 per year to run a TiVo.

((40 watts * 24 hrs per day * 365 days per year) / 1000 ) * .041 kWh rate = ~$14.38 per year

This might sound a like a lot of money but it really isn’t when you compare it to the cost of running a PC 24 hours a day (~$43.13 per year not including the cost of a monitor).

Along with being a super geek, I’m also a bit of a stickler when it comes to energy usage. If I had to classify myself, I would say that I am a cheap-geek :). I enjoy technology but I’m always looking to save a buck especially when it comes to energy usage. That being said, I came across this article on news.com. The article talks about how we as consumers are using more and more electricity for our techno gadgets.

Being the cheap geek that I am, I thought I would analyze how much it costs to run a TiVo 365 days a year. I found this formula online however, I don’t know how many watts a TiVo consumes. Anybody have an idea?

    My 80-Hour Humax TiVo’s specs say 40W, which seems really low, but that’s what it says! http://www.humaxusa.com/products_T800_80.html If I correctly calculated through their formula, that’s right at $50/year. Way less than my desktop computer would cost, which is on 24/7 as well.

    [...] I’m such a tight-wad when it comes to certain things. One of my pet peeves is walking through the house and seeing lights and TV’s on in rooms that nobody is using. I recently stumbled on this site, thanks to the TiVoBlog folks, that gives you a formula for figuring out how much it costs to run the various items in your house. Obviously their concern was for their TiVo. [...]

    The back-panel rating is very conserative. I’d probably guess that the current draw is 0.1-0.2 amps, more when the system is recording. You’d need to use a time-weighted average, so’d it probably be 0.125 amps, or about 15 watts.

    At 8c/kWh, it’s about $10-11 per year.

    Here’s an email that I received from Brian. I thought I would share it with everybody:

    Hello,
    Your article on TiVo energy usage intrigued me, and it’s something that I have also wondered about. I recently purchased a device call a Kill-A-Watt, which is an electric meter specifically for measuring this type of thing. I ran a few quick tests, and here’s what I got on my Series2 TiVo unit:

    - Startup: There was a 1 second peak at 40W a few seconds after starting, but then it went down and fluctuated around 24-28W
    - Running “idle” (not recording): 28-29W
    - Recording: 28-29W

    I did not notice any significant changes while navigating menus, looking up program information, etc…

    The 40W listed on the power supply and in the specs is most likely the maximum usage, but during normal use it should not be at maximum. Individual units may vary slightly in their readings.

    4 cents a KWH? Where do you live? I’m moving there.
