Likely so. IF they got away from R-134A with a refrigerant that has a much lower head pressure I might see 50% reduction. The R-134A is about 100 psi higher on the condenser side of the unit than the older R-12. Compressing a gas too 250 psi takes considerable energy.
I did wire in a very low energy chest freezer designed for solar powered homes for a friend. Considering utility power was not available for him the freezer was better than nothing but not by much. Took it forever to pull down. First one he got ran a week before failing.
