Cable TV boxes become 2nd biggest
energy users in many homes
Los Angeles Times
In the middle of the night, when most Americans are sound asleep, their lights and appliances off, a power hog is wide awake and running at nearly full throttle: the boxes that operate their cable or satellite television service.
The seemingly innocuous appliances — all 224 million of them across the nation — together 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.
A 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. The devices use nearly as much power turned off as they do when they are turned on.
. . .
The set-top boxes consume power when turned off because of spinning hard drives, program guide updates and software downloads, leaving consumers with one choice to reduce that load: Unplug the device. The downside is that turning the system back on requires a convoluted reboot.
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.
