electronics use almost 40% of their normal wattage even when switched
I wonder if that is from the same people who convinced some friends years ago that switching flourescent lights off and on made them use double the electricity so they should be turned off as little as possible.
What we need there is to move as quickly beyond fluorescents with their hideous spectral characteristics to high-output, LEDs for home and office lighting. (Not that I'm agreeing with the silly contention that switching fluorescents increases their power consumption.)
I guess it is the curse of being an engineer; I am going to have to measure the power use of my TV tonight.
That's a special case of the curse of being intelligent and well-informed... 40% is extremely unlikely for a TV, but a reasonable estimate for a clock radio, perhaps. I've heard estimates that the "vampire" devices--those that remain powered when "off" so as to be amenable to remote control--consume about a gigawatt in the U.S. What's the total capacity of the North American power grid? Clearly it's far above the 2.5 GW that would be consistent with the 40% number. Check out http://www.worldchanging.com/archives/004379.html, http://standby.lbl.gov/Data/SummaryChart.html and http://standby.lbl.gov/Data/SummaryTable.html. A priori, I'm inclined to give credence to a study on power consumption by Lawrence Berkeley National Lab.
