I thought I was just grabbing numbers ofv the top of my head
But no - it REALLY is that bad for refrigeration.
My original source was a slide that was distributed internally a few weeks ago at my workplace where - along the more important markets for us like India, China and the EU - it showed US ratings.
Those were normalised numbers for one model to what the equivalent rating would have been under each system.
And that was absurd.
But looking at it now, it REALLY blows me off my socks.
Luckily (though I personally despise that trend) the US-style side by side has become the next status symbol in EU Kitchens.
And luckily, manufacturers like LG sell similar sized units on both sides of the pond:

https://www.lg.com/de/kuehlschraenke-gefrierschraenke/lg-gslv31mcxm
Those are the same dimensions basically, same internal volume more or less, both have an ice maker.
And either your testing procedures are inherently so different that it is beyond my comprehension, but the US equivalent uses 600+kWh a year compared to the 400+kWh in the EU - and that model is F-rated, so won't be legal to sell after next March here.
Edit:
Findung and understanding testing methology takes some time, but I got there eventually.
So, most fridges in the EU are tested at both 16C and 32C ambient temperatures.
DOE testing runs at 32C non stop to simulate door opening.
The EU has a very convoluted calculation system, and the values behind that aren't usually made public - BUT there are a hadfull of listings that show the values.
The one model I could find info on that made sense was a Beko side by side.
It's sizing is comparable to that LG, and it's rated F aswell, features are similar.
It uses 1.508kWh in 24h at 32C under EU testing.
That is more or less exactly 550kWh yearly - still 100kWh less than the US LG.
And again, F-rating is the worst of the worst so to speak.[this post was last edited: 2/19/2023-12:24]
