What a set-top box is and does is rapidly evolving. If current trends continue, by 2010electricity use by set-top boxes in the U.S. could approach 4% of total residential electricity use.In order to reduce this use, many programs and activities are underway in the U.S. including anENERGY STAR? specification (now being revised), consideration of minimum efficiencystandards in many states, and discussions of a variety of voluntary programs involvingequipment manufacturers, cable and satellite TV providers, and efficiency experts. In addition, avariety of research is underway to better understand set-top box energy use and future trends, andto develop additional intervention strategies. This paper summarizes the current state-ofknowledgeof set-top box energy use in the U.S., and describes current and emerging strategiesfor reducing this use.
