I hear you, but I just don't buy that it's a significant issue. In fact, I don't think it's an issue at all.

I may have mentioned /my/ PC, but you don't know what I do the rest of the time, so no need to get cocky with yer 'we mostly do business' - I couldn't give a toss what you do. As it happens, most of the fixes (apart from hardware) I do for people are either malware or crappy/incompatible windows updates. Thinking about it, some of you folks out of the AV group are belligerent little buggers aint'cha? -- SteveH

If you assume a power savings of 50 watts (low power state versus off state) and a KWh cost of $.10, my back of the napkin calculation is just under $15 a year in savings. Obviously, the actual numbers will vary depending on the specific system and the local cost of power, causing the result to vary.

Not very difficult to see how much wattage your system is actually using in a low power state... Bad to just take a guess and try to pass that off as knowing... ? -- "Hrrngh!

With a motor, it takes more ( > less) power until the motor spins up to generate the opposing "back voltage" that a spinning motor generates. Running for some period of time is equal to this power consumption. De-energizing for less than that period of time will not save you any power. As for the bulbs, there is that factor plus the efficiency and the life expectancy of the bulb is reduced with multiple starts (though I don't know exactly why).
