1. There is not enough data. Are each appliance energy efficient or not?

However, you should be aware that the freezer changes in the amount of energy it uses. It uses more energy, once the temperature gets above a specific amount. That point will vary, depending on how much is in the freezer, whether it is already frozen, how many times a day the freezer is opened and how long it is open.
