I didn't say CPUs always take 80 watts.  But I believe that's
not a bad number for the whole package, it's what I measured
my server at.

Not all California pays the 14 cents we pay here, I agree.

Well, no, that is indeed what many always-on servers with 3 disk drives
and a high speed processor and a fancy graphics card and various other
cards do indeed draw, all day long.  More when they are playing HD, transcoding
or commercial eliminating, which they do several hours a day in many myth
systems.   The supposed average family that watches 6 hours/day (I think that's
crazy but you keep seeing numbers like that) is going to use their CPU a lot.

How about my power bill?  14.1 cents per kwh.   How about the specs on
the components in the systems or power meters?
