Refrigerators consume a lot of power, however, they are also modern kitchen equipment. So you will have some power savings. After heating, cooling, and hot water systems, they're the top energy users in most houses. That is why the refrigerators in India have Star power ratings. You can look at them. The 5 Star Refrigerators consume lesser power in comparison to the same capacity product of a different volume. But a the same time it is also expensive. So, I suggest you go for 4 stars to 3-star refrigerators, in the budget ranges.
