Turns out that one of the most inconspicuous home fixtures is one of the biggest energy hogs — even when they aren’t recording or replaying programs!
Digital Video Recorders (DVRs) allow users to record television programs to a storage device (hard drive, memory card, etc.). They also use more electricity than a refrigerator! (albeit, an energy efficient one.)
The startling state of DVR efficiency was brought to light by the Natural Resources Defense Council (NRDC). The report finds:
In 2010, set-top boxes in the United States consumed approximately 27 billion kilowatt-hours of electricity, which is equivalent to the annual output of nine average (500 MW) coal-fired power plants. The electricity required to operate all U.S. boxes is equal to the annual household electricity consumption of the entire state of Maryland, results in 16 million metric tons of carbon dioxide (CO2) emissions, and costs households more than $3 billion each year.
Remarkably, “U.S. set-top boxes continue to use almost as much power when not in use as they do when in use. However, leading European service providers have begun to solve this problem in their newest boxes”:
According to NRDC, there is much that can be done to improve DVR efficiency including:
Meeting ENERGY STAR requirements
Manufacturers are strongly encouraged to design products that meet or surpass ENERGY STAR Version 4.0 requirements as soon as possible.Employing Automatic Low-Power States
Future products should automatically enter a low power state when the user is neither watching nor recording or downloading a show, and should wake up in a sufficiently short period of time to prevent customer dissatisfaction.Replacing Outdated and Inefficient Set-Top Boxes
Service providers should accelerate deployment of new energy-efficient set-top boxes and make any needed changes in their “upstream” equipment to ensure the energy saving features are successfully utilized. Service providers are encouraged to shift to multi-room solutions that require only one main box and employ much lower power boxes (thin clients) to view content on other televisions in the home.Spurring Technological Innovation
Service providers should work with their supply chain and industry groups to accelerate adoption of standards that enable:
- Multi-room clients to achieve deep sleep with short wake time
- Connected consumer electronics devices such as the television, set-top box, and DVD player to share power state information in support of more effective power management
- Data connections should operate at lower power levels when not in use
- Service providers to wake set-top boxes from deep sleep
With a little commonsense and ingenuity, your favorite television program can be enjoyed anytime of the day — without burning up your money and the planet.

Low-Income Students Attend For-Profit Colleges At Four Times The Rate Of Other Students
According to a study by the Institute for Higher Education Policy “in the last 10 years, low-income students have increasingly being drawn to proprietary colleges and now attend at four times the rate of other students.” The study finds that students “whose total household income is near or below the federal poverty level are likely […]
According to a study by the Institute for Higher Education Policy “in the last 10 years, low-income students have increasingly being drawn to proprietary colleges and now attend at four times the rate of other students.” The study finds that students “whose total household income is near or below the federal poverty level are likely to be overrepresented at for-profit institutions and underrepresented at public and private nonprofit four-year institutions.” As we’ve documented, many of these subprime schools make up to 90 percent of their revenue from the federal government, yet leave their students crippled with debt and with bleak job prospects. Several of the schools have been charged with using illegal recruiting practices aimed at low-income students.
