You fridge should consume between 100 and 200 kWh a year, depending on efficiency and size. 30kWh a year is a notable saving, between 10 and 15€ a year, if you keep the machine 10 years it’s like a third of the price. If you have kids more than that, since you run it more than one a week.
I feel this way about washing machines already. Oh wow, this one uses 0.6kwh less per wash. That’s like 30kwh a year!
