Where are you that you get electricity for .05/kWh?  Here in Oregon we
have pretty great rates, and I think we're paying .10-.12/kWh.

And if $1 of electricity (heat) is going in to a device, you can expect
to spend another $1 to cool off (remove) that heat.  Yes, there are
times one can put a machine somewhere that it does not need to be
cooled, but if the machine is in a "living space" it's adding to the
heat transfer load.

In an increasing number of places, electricity rates are "tiered", and
one can spend a lot more per kWh between noon and 7pm (for example) than
for other times of the day.
