Bullshit on the fridge. A modern day french door uses almost 2 kWh per day at the mid range model level (which really isn't that different from older top freezers). Higher end fridges use even more. The 1.6 kWh capacity isn't enough for 2-3 days.

Sadly, a modern day french door is pretty inefficient. Consumers prefer them because of their looks but they are very far from being an efficient way to keep food cold.

Why are they any less efficient than a single-door fridge? Losses in between the two doors? I don't see why it should be much different. Both types of fridge causes the cold air to "fall out" when you open the door(s).

A top-loading chest fridge/freezer is of course most efficient, but don't think many people have those in their kitchens.

French door has less insulation because there's more "seams". Also typical french doors tend to have an ice machine or water dispenser, which is even less insulation and/or more seams.

That’s a lot of energy! What fridge do you have?

According to this, it really is not:

Wow, I was surprised by this claim too, and found the specs for my fridge[0]. 755 kWh/yr, which works out to just over 2 kWh/day. Damn, that's a lot!

Check out this[0] and think about regional markets: half the capacity with 108kWh/yr consumption. I had theirs previous gen one and can attest that the number is correct.

Wow that’s crazy! What fridge is that?
