Really, that stuff is small potatoes. Look outside at night time and see how much power goes into lighting. Then heating/cooling, large scale manufacture.

It was fashionable a few years back to turn off your devices 'at the wall' so stop so-called 'vampire use' - which was TVs and other equipment on stand by. It sounded plausible - but in reality is just noise in the overall consumption picture, and is just window dressing to make people feel like they are doing something.

I'll agree that idling PCs and monitors should go into sleep mode like laptops do, but that stuff is not going to make the slightest dent in consumption anyway. Compare the power consumption of an electronic device with something like an iron or a stove or a clothes dryer and you'll see why. And that's before you start looking at heavy industry and large-scale building temperature control.
