Television, others consume 13% of US electricity supply

The United States Consumer Electronics Association has published a study that shows domestic electrical devices account for roughly 13 per cent of the average US homes electricity consumption, cellular-news reported on Thursday.There are nearly 2.9 billion CE devices in US households and an average of 25 devices per household, including battery-operated CE devices. Home use of CE devices equaled 13.2 per cent of overall residential electricity consumption and 9.3 per cent of residential primary energy consumption. Within that 13.2 per cent, televisions accounted for 34 per cent, Personal Computers 16 per cent, and set-top boxes 13 per cent.For instance, the study estimated the installed base of televisions rose to 353 million in 2010 from 342 million in 2009, though unit energy consumption declined slightly because of the shift from legacy cathode ray tube TVs to more efficient flat-panel TVs.The study was commissioned by CEA and conducted by the Fraunhofer Center for Sustainable Energy Systems to quantify the electricity consumption of CE products in US households in 2010. Devices covered in the study include: audio-visual equipment, audio video receivers, Blu-ray players, DVD players, televisions, video game consoles, set-top boxes (cable, satellite, telco and stand-alone), computers and peripherals, PCs, computer speakers, monitors, networking equipment and printers."Given the quick pace of change in our industry, it is important to have a comprehensive assessment from time to time," Johnson added. "Too often we have seen unnecessary government mandates advanced on the basis of poor data and analysis. We hope this latest study is a welcome contribution to current and future policy and program discussions."The Fraunhofer report follows a study released by the Brattle Group last month that estimates US energy consumption will drop five to 15 per cent by 2020.According to the authors, economists Ahmad Faruqui and Doug Mitarotonda, the drop will occur due to an increase in ENERGY STAR appliances, less usage of incandescent light bulbs, incentives that encourage users not to consume as much energy during peak hours, and other programmes that raise awareness of peoples energy consumption.
