The Consumer Electronics Association(CEA) commissioned this study to quantify the electricity consumption of consumer electronics(CE) in US households in 2013 as a follow-‐up to the two prior studies it commissioned for 2006(Roth and McKenney 2007) and 2010(Urban et al. 2011). Relative to other energy end uses, the CE end use characteristics typically change very quickly due to innovation, short product cycles and lifetimes, evolving usage patterns and dynamics, and rapid technology adoption that can strongly influence device power draw by mode. As a result, the characteristics of the installed base of most CE have changed dramatically since the first study.

Such rapid changes in the energy consumption characteristics of CE make it essential to develop up-‐to-‐date and accurate assessments of CE energy consumption. If older data are used to analyze potential energy policy decisions, such as voluntary or mandatory regulatory programs, they can lead to less effective policy decisions that may not achieve their end goals. Consequently, CEA commissioned this follow-‐up study to provide high-‐quality data to inform public policy decisions affecting CE.
