Did this electrician use a simple Watt meter before making these napkin 
calculations?   Unless these two computers have attached CRT's turned on 
24/7, I would be *really* surprised if combined these are using more 
than 150W, (3.6 KWh / day, * 30 = 108KWh)  Still worth reducing, of 
course, but that should cost less than half than this $30 estimate.
