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 the

  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. [1] https://energyeducation.ca/encyclopedia/Appliance https://energyeducation.ca/encyclopedia/Appliance
