A recent study released by the Consumer Electronics Association has found that the overall level of electricity used by household electronics has reduced since 2010. The report found that the amount of energy used by these devices has decreased by 13% over a three year period. Two of the biggest reasons for this decrease are improved televisions and improved personal computers. According to an article from the MIT Technology Review:
Televisions continue to account for the largest portion of power consumption by electronic devices in U.S. homes, consuming 30 percent of the total used by the devices covered in the report. But TVs consumed 23 percent less electricity in 2013 than in 2010. The authors attribute this to there being 50 million fewer TVs in use and to a “massive” shift away from power-hungry cathode ray tube displays to more efficient liquid crystal displays.
The second biggest drop in consumption occurred in personal computing. Power use by desktop PCs declined substantially, largely because there were fewer in use in 2013 (88 million) than in 2010 (101 million) and because of an increase in the amount of time the computers spent off or in low-power mode. There was also a decline in the use of external monitors, along with a 10-fold increase since 2010 in the number of households with at least one tablet. Tablets consumed about 0.6 terawatts-hours in 2013.
As household electronics are one of the biggest sources of overall electricity household use, the fact that they are becoming more efficient is beneficial for consumers. As the study suggests, newer models of household electronics are becoming increasingly energy effifienct. This more than likely means that consumers who are in the market for new household electronics will be able to save on overall electricity costs if they decide to buy these newer models.
