Those can be had for about 20 eur or so from your local superduper market, and they're a great fun to plug into things. Combine with a calculator, your hair will rise up when you put the meter between the wall outlet and the extension cord that has all your entertainment systems at home or at work: mine was pulling 100W+ when in sleep mode, yikes! Our internal test servers (2 of them) were pulling around 120W each - and we never use them outside regular office hours, and even then not every day. Both of these are super easy to just turn off when they're not in use, it just never occurred to me to check if they really use much electricity. Well they do - or maybe I should say did, 'cause now I'm shutting them down for good when not used. A great motivational tool is an electricity consumption meter.
