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.
