Cable Boxes Consume 'Startling' Amount Of Electricity: "The groups say their findings were startling. 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.
How can such a relatively small appliance use so much electricity? Today’s set-top boxes operate at near full power even when the consumer is neither watching nor recording a show. As a nation, we spend $2 billion each year to power these boxes when they are not being actively used.
Boxes equipped with digital video recorders (DVRs) use even more electricity. DVRs typically use around 40 percent more energy per year than their non-DVR counterparts, the study says."
