Picked up one of these, and I've started taking some measurements around the house. I assume 15 cents per kwhr for the calculations.

- Delonghi PAC10 Portable Air Conditioner 8500 btu
7.40 amps
830w
1.81 kw/h for 2:18
.787 kwhr per hour (12 cents per hour)

- Nintendo Wii
standby: .18 amps, 13 w, 0.013 kwhr per hour (.2 cents per hour at 15 cents per kwhr so about a nickel a day to keep the wii in standby)
during zelda: .27 amps, 20 w

- HTPC idle at desktop (athlon 2200 xp)
1.58 amps
121w
2.91 kwhr for 23:52
0.121927 kwhr per hour
44 cents for 24 hours (about $13 a month)
