The power utilisation of a refrigerator scales at best poorly with the quantity of food moved through it, unlike a smartphone (door openings is a far greater predictor), and human food consumption is generally constrained (1800-3200 kcal/day per person, more or less), whilst data appetites both vary and have grown markedly.

You do raise a good point that behind msny. products is a long chain of either embedded manufacturing or complementary products costs. But the avoidable costs of food vs. data (refrigerated or not, people need food to eat; we'd survived 200,000 years before iOS) argues against your comparison.

That's a false equality. Counting food would be analogous to counting the energy used to build the apps. The fact that a fridge has less features that require additional power draw don't detract from the point.
