Leaking Electricity: Individual Field Measurement Of Consumer Electronics, Florida Solar Energy Center, David Floyd

FSEC Energy Research Center®

Leaking electricity or "parasitic load" is energy wasted by electronic devices when they are not performing any useful function, typically in an "off" or "standby" state. Before this study, little was known about the magnitude or source of this waste. While whole house losses have been estimated to be approximately 50 watts, little data has been available to quantify energy waste from individual loads. This paper summarizes measurements of over 600 consumer electronic devices taken by researchers at both the Florida Solar Energy Center and Lawrence Berkeley National Laboratory. Combined they form the largest data set of consumer electronic loads …
