Which is why I always laugh when people say to replace a 15 year old fridge to “save” on electricity.

Really depends on how much your electricity costs relative to your efficiency gain on the new fridge.

But refrigerators are also largely a "solved" technology. We aren't radicallu changing how we run a compressor or insulate a unit. I ended up getting a new one recently because my old refrigerator's repair bill was going to be as much as a new unit.

Now, if units were more modular and easier/cheaper to repair? The math changes.
