I'm looking for a small compact 1.7 cu ft refrigerator for my office. A
freezer is not really necessary, but if it doesn't cost more to run I guess
it might be used several times a year, and ice would be nice to have if
needed.

None of the units without freezers are "Energy Star" rated (and when
comparing some of the same models with and without freezers some
specifically  say Energy Star COMPLIANT "yes" to freezer model, and "no" to
non freezer models).

I'm not sure if this is saying that non freezer units are just not rated,
but use the same amount of power as the freezer units and whether they are
not compliant just because they are not rated.

I would assume it would cost more to run a freezer, than not. So if the
freezer unit is ES compliant and the non freezer is not, which should cost
more to run -  an ES compliant freezer, or non ES compliant non freezer
unit?

Obviously if there were specifications with current draw I could compare
something, but I don't see that given anywhere.

Thanks
