As energy costs keep rising, the green juggernaut continues to grow. In response to energy concerns CEA just released a white paper entitled, "Energy Consumption of Customer Electronics in U.S. Homes." Written by the Fraunhofer Center for Sustainable Energy Systems.
This 142 page report includes the sleep, standby, and operating mode current draws for most electronic devices, including Audio Video Receivers, Blu-Ray players, DVD/VCR combos, computers, computer speakers, monitors, printers, set-top boxes, TVs, video game systems and other devices. Audiophiles will be disappointed to find there's no separate category for power amps, preamps, music servers, or subwoofers.
The report also has breakdowns of how much various devices are used in households. Among the surprises - 80% of the respondents reported no use for Blu-Ray while 1% reported 24 hours per day use. Now that's what I call a wide usage spread.
Judging by the numbers, most AVRs are pretty darn energy efficient. In off mode AVCRs used .2 watts, in sleep mode less than 2 watts, and in standby mode between 48 and 39 watts. When unplugged AVRs get a perfect energy rating of 0 watts used.
Take a look at the white paper for yourself - you'll find lots of factoids that will spice up any holiday party conversation, maybe.
