How to cut your electricity bill

leave a comment »

Switch off your set-top box, is the advice this article from NYT seems to give:

Those little boxes that usher cable signals and digital recording capacity into televisions have become the single largest electricity drain in many American homes, with some typical home entertainment configurations eating more power than a new refrigerator and even some central air-conditioning systems.

One high-definition DVR and one high-definition cable box use an average of 446 kilowatt hours a year, about 10 percent more than a 21-cubic-foot energy-efficient refrigerator, a recent study found.

These set-top boxes are energy hogs mostly because their drives, tuners and other components are generally running full tilt, or nearly so, 24 hours a day, even when not in active use. The recent study, by the Natural Resources Defense Council, concluded that the boxes consumed $3 billion in electricity per year in the United States — and that 66 percent of that power is wasted when no one is watching and shows are not being recorded. That is more power than the state of Maryland uses over 12 months.

The perpetually “powered on” state is largely a function of design and programming choices made by electronics companies and cable and Internet providers, which are related to the way cable networks function in the United States. Fixes exist, but they are not currently being mandated or deployed in the United States, critics say.

Similar devices in some European countries, for example, can automatically go into standby mode when not in use, cutting power drawn by half. They can also go into an optional “deep sleep,” which can reduce energy consumption by about 95 percent compared with when the machine is active.

One British company, Pace, sells such boxes to American providers, who do not take advantage of the reduced energy options because of worries that the lowest energy states could disrupt service. Cable companies say customers will not tolerate the time it takes to reboot the system once the system has been shut down or put to sleep.

The set-top boxes in India are less obnoxious, but still extreme power guzzlers. We power off the set-top box from the wall power switch at night. It then stays completely off until the first person in the house wants to watch TV. Once it is switched on it stays on till night. We still manage to cut down its power consumption by half. It would be better to have a device which can intelligently put itself to sleep.
