This has a similar feel to the “does the use of a power inverter while driving a car dramatically decrease gas mileage?” question. But the question at hand is: does a refrigerator use more energy when it’s full as compared to when it is empty. My thinking is that it does. If there is one water bottle in the fridge and one outside of it, the one in the fridge has used the cold air in the fridge to cool itself down, while the one outside has obviously not, but if you put the second one in the fridge that bottle will use the cold air in the fridge to cool itself down as well. Now the fridge has to supply twice as much cool air to cool both bottles than it would it there was only one. (I use the term “air” loosely)
I would love to hear what every one has to say… especially if I’m right… my girlfriend has taken the opposing side.
Thanks.
