Were shopping new refrigerators in August of 2014. I noted a wide discrepancy in the ratings of some refrigerators (Samsungs) from others. It turns out that there is a new EnergyGuide label (more black on yellow), and this relates back to new and different energy test protocols. These new tests are more realistic supposedly, and reflect more realistic energy use. Walking through Home Depot and Lowes, it turns out that only Samsung is providing units with the new labels. So if shopping and looking at energy, you cannot look at the labeling with the two different styles of label, and compare side by side. Interestingly, Consumer's reports claims that they do their own efficiency tests to identify operating costs, and they differ from what the energy guide labels claim. Interestingly, some of what I've seen on the old labels is similar to what CR says,and some are vastly different. So I don't know who/what to trust, but the values are changing, as are the tests, so just beware.
