Cable Boxes Are the 2nd Biggest Energy Users In Many Homes

SpzToid (869795) writes 224 million U.S. cable TV set-top boxes combined consume as much electricity as produced by four giant nuclear reactors, running around the clock. They have become the biggest single energy user in many homes, apart from air conditioning. Cheryl Williamsen, a Los Alamitos architect, has three of the boxes leased from her cable provider in her home, but she had no idea how much power they consumed until recently, when she saw a rating on the back for as much as 500 watts — about the same as a washing machine. A typical set-top cable box with a digital recorder can consume as much as 35 watts of power, costing about $8 a month for a typical Southern California consumer. And the devices use nearly as much power turned off as they do when they are turned on. The article outlines a voluntary industry agreement that should make a dent in this power consumption (it "calls for a power reduction in the range of 10% to 45% by 2017"), but makes the point that much larger gains are possible: "Energy experts say the boxes could be just as efficient as smartphones, laptop computers or other electronic devices that use a fraction of the power thanks to microprocessors and other technology that conserves electricity. Ideally, they say, these boxes could be put into a deep sleep mode when turned off, cutting consumption to a few watts. At that rate, a box could cost less than $1 a month for power, depending on how much it is used."

      Yes, all of us programmers are smart enough to realize you could just trigger the auto-wake a minute or two early, but they don't do that... and that's not the fault of your cable company it's the fault of Motorola, ARRIS, Pace, and the other makers of the actual equipment. Their code is clunky and shit, and to top it off someone asswipe company probably has a software patent on 'waking up the box prior to the recording start time to minimize power consumption'. Yes, really.

      Bullshit.

      It is the cable company's fault precisely because the cable company, not the user, is choosing which cable boxes to buy and the cable company (unlike the user) doesn't give a shit about user experience. If cable boxes / DVRs were sold retail instead of rented there would be competition and the manufacturers would be forced to get their shit together!

      CableCard was designed to fail. It wouldn't exist at all without the FCC mandate (trying to break the cable company's stranglehold on STBs), so they went out of their way to make them as inconvenient and discourage people from using them. Cablecards are a threat to the traditional vertical monopoly cable companies enjoy, which is why they are trying so hard to make them a failure.

  8. Disingenuous Summary by clonehappy · · Score: 4, Insightful

    Which is it? 500 watts or 35 watts? This summary and title are completely ridiculous, I can think of plenty of other things that are using more power in my home than a cable box. Refrigerator, freezer, washer, dryer, hair blow dryer, desktop computer, television, central heating/air conditioning, range (if it's electric), power tools/garage, home theatre system, the list goes on and on.
     
    The reason the "500 Watts!!!" is disingenuous, is because many cable boxes have a switched outlet that allow you to plug in a television set to the back of it. Back in the good ol' days, you could click on the cable box and the TV would turn on as well, if it was plugged into the back. That CRT might draw as much as 500 watts, so that's what it's rated for. With the advent of universal remotes, electronic controls in sets that forget the last power setting and the need for constant power to keep settings and "quick-on" for many sets, this is now an antiquated port that's just a hold over from the olden days of cable TV.

    Plop a "kill-a-watt" on your cable box and turn it on, note the power used. now hit the "off" button the remote. See how the power use did not drop. That is because "OFF" is simply blanking the screen and turning off the front led's and display.

    It's why most pro AV installs will put the cable box if it's not a DVR type, on a power sequencer that the control processor will turn on and off with the system. The drawback is some of the newer cable boxes take forever to boot after power is restored.

      Putting a cable box on the sequencer is a bad idea. Almost all STBs will lose all of their guide data, which can take hours to repopulate, in addition to taking forever to boot up. Occasionally they will even lose their subscription information if you are out of town/country for a few weeks. I wouldn't recommend it.

    This is the same way Light Dimmers are rated. A 600 Watt dimmer does not consume 600 Watts, but can handle a 600 Watt chandilier with 6 100 Watt bulbs.
