This is something I have been commenting on for a long time in
relation to services that require the use of a PC to operate (e.g.
Skype etc.) I maintain that you need to add the cost of running
hardware to the cost of your telephone service.

Even a very modest modern PC consumes 70Wh (without the monitor) -
many others take much more.
I did an audit on hourly power consumption of other devices in my
house when on standby.
This might surprise you:-
Sky box 19W
Netgem DTT STB 8W
DVD 16W
VCR 5W
Hard disk DTT recorder 23W
Cordless phone (satellite NOT main base) 2W
There are 4 cordless phones in total but it isn't practical to switch
those off. The remainder of the above items, however, use up approx.
52 units of electricty per month. That's 624 units per year. At
9p/unit that's GBP56/year! A 70W computer (AMD64 2800 for example),
running 24/7 for Skype, would ADD another GBP 55/year to that.

I don't leave my PC switched on and I have since unplugged most of the
above. The Sky box is now on a timer so it is switched off during the
night.
