Are new refrigerators more efficient than older ones?
Supposedly.... Most new appliances come with KWH annual usage posted on them.
Not in my experience. I have two refrigerators that are only 2-3 years old. It all comes down to marketing--- how you define "efficiency." IMO, these newest frigs are not necessarily what I would call more efficient, but they are made to run on (use) less electricity. Call back to your 'physics 101' classes of yesteryear to recall that less electricity = less power. My old fridge had a cold spot in the freezer that in 2 hours I had new ice cubes--- in the new fridge, bragging of having no cold spot like it was a selling feature, it might take up to SIX hours to make the same ice cubes. Fact is, the new stuff simply does not cool down as cold--- that might save electricity and give you lower/better marketing numbers, but the freezers simply do not go down as cold as the old ones.
Another thing is that years ago, there were a whole bunch of competing companies making different frigs, but my understanding now is that those companies no longer exist--- they have all been bought by just two companies, Whirlpool and Frigidaire.
