I shopped for refrigerators 3x in my life; I will get to go shopping for another one soon, darn-nit $; and of course, thinking about the electric bill next the unit's depreciation. Honestly, the refrigerators that has the different compartment/doors with a good seal, these parts you are not going to believe: 1.The filtered water unit/spout should be inside a different compartment/door; 2. Nowadays, if you need a freezer, it should be made to benefit the whole refrigerator unit, because some don't! (Maybe a separate freezer unit might be the best even if you need a small unit); 3. A compartment that gets opened regularly is important. Remember the star label is important, or look into that solar panel's for running a refrigerator. I know they have the whole house water heaters with the solar panels which makes it one unit is out there.
