He specifically states the setup draws 220 watts at idle and that his electricity costs $0.0974/kWh. So 22024/10000.0974 = 0.514272 per day, or about $15.40 a month at idle.
yea if it's idle the entire month, which is doubtful. but even if it's not, it's not likely to be too much more than the $135 you calculated. I figured the internet service would have been more, since the rest of us get screwed by our ISPs on costs.
