Once frozen it does not cost any measurable amounts to keep it frozen.

Nope. You don't understand the thermodynamics of sublimation and the heat
of fusuion and vaporization, and the practicalities of modern appliances.

You pay energy first to sublimate ice to vapor if they're loose in the
freezer. This is why they shrink over time, and why frozen food dessicates
if not in a vapor barrier.

Most frozen food is contained in vapor barrier packages. How much energy
would we save if we kept ice trays in a baggie?
