An average of 25 devices per household make up the usage, with television usage the highest consumption. 
A new study from the Consumer Electronics Association entitled “Energy Consumption of CE in US Homes in 2010” has revealed that consumer electronics account for a surprisingly low amount of US home electricity consumption, at 13.2 percent, despite their popularity.
Within this figure, television accounted for 34 percent of usage, with PCs making up 16 percent and set-top boxes 13 percent. The study states there are nearly 2.9 billion CE devices in US households; an average of 25 devices per household.
Douglas Johnson, CEA Vice President of Technology Policy, commented: “This landmark study provides a recent and comprehensive assessment of CE energy consumption, which is helpful to policy makers and others interested in efficiency trends. Energy efficiency improvements in consumer electronics are driven by innovation, competition and market-oriented programs such as Energy Star.
“Given the quick pace of change in our industry, it is important to have a comprehensive assessment from time to time. Too often we have seen unnecessary government mandates advanced on a basis of poor data and analysis. We hope this latest study is a welcome contribution to current and future policy and program discussions.”
