Suppose my power company claims that the charge is

or $1.73 a month. I've been under the impression for quite some time that
it costs $20 a month to run a typical modern desktop computer 24 hours a day
for a month. I know there are taxes and fees thrown into the power bill.
But what's wrong with my math? Was I wrong before or am I wrong now? I got
this kw/h price from the power company web site burried in a pdf somewhere.
It looked like the right price to me. Maybe the actual charge is much
higher?
Brian, you might want to get yourself a gadget called a "Kill-A-Watt".
You can plug your PC's power strip into it and see exactly how much power
your computer consumes. They cost about $25.
