We have always wasted electricity without knowing it

For freezer compartments, if storing a lot of fresh food such as seafood, it is best to maintain a high cooling level at around -18°C. This temperature prevents bacterial growth and keeps food fresh for a longer period.
Additional Tips to Save Electricity with Your Refrigerator
Besides adjusting the temperature, experts recommend the following energy-saving habits:
1. Place the Refrigerator in an Optimal Location
Refrigerators release heat from the back or sides. If heat dissipation is obstructed, energy consumption increases.
Keep the refrigerator at a reasonable distance from walls or other objects to allow proper airflow.
Avoid placing the refrigerator near heat sources such as microwaves, ovens, or stoves. Too much surrounding heat forces the refrigerator to work harder, increasing energy usage and reducing its lifespan.
2. Avoid Keeping the Door Open for Too Long
