Bad example, it is actually better to replace older fridges (older than 10 years though) with modern low energy designs, obviously with the expectation that they'd last longer than 3 years.

Fridges and Freezers are the only appliances I'm aware of where it works out like that though.

Edit: Here's a case study for those that don't believe me.

That's just savings in end-user monetary expenses, which is a proxy for energy use, but not necessarily a good one.

I wonder whether this calculation holds once you account for the energy used to develop, construct, market and transport the new fridges that replace the older-but-working fridges. It's a genuine question - I haven't seen such calculation done. My current intuition is that the extra marginal energy used in manufacturing a new fridge dwarfs the energy savings of replacing the old one before it dies.

The link gives a figure of 700kwh saving a year.

This [1] gives the embodied energy for a fridge as 5900 Mj which equals 1600 kwh.

So broadly speaking you new fridge 'pays' for itself in 2 years. I suspect its worse that, but even if its 5 years, my point still stands.
