Compared to heating with electricity, for instance, freezing is a =
relatively=20
efficient process, as it is based on the Carnot cycle. Take heat at one =
temperature
and dump it at a higher temperature. Thermodynamically very elegant!
Microwaving is a process of heating with electricity, but, compared to =
resistive
heating in an enclosure, it is quite efficient as only the item needed =
to be heated
is heated. Microwaving a daily portion of frozen bread is entirely =
optional, as
the bread will thaw rapidly at room temperature.

Over the years, gas of one kind or another, or petroleum fuels, have =
been a very
cheap kind of energy. But clearly those days are coming to an end. =
Possibly another
age of artisanal ovens on the countryside is coming.

I do not know how refrigeration and freezing works in a trailer home, =
but I assume
that it is gas (i.e., propane) fueled. That should still be relatively =
cheap, if space will

one uses
the same fuel for the bakes, as opposed to gathering wood in the =
forests.
