We’ve heard it again and again – but do you know how much energy your equipment really uses when on standby? Or your computer when supposedly turned OFF?
I was indeed “shocked” to find out that both my desktops, a Shuttle XPC and a home-made Mini-ITX-based HTPC, each use more than 20W when TURNED OFF! I guess this is waste from the AC adapter and power for the USB – but… this is completely crazy. Over 24h, this is half a KWh. To stop the energy usage, I had to use an external power switch. However, this makes it impossible to automatically wake up the HTPC for recordings.
OTOH, my notebook only draws 3W when shut off.
