In an attempt to save on their electricity bills, many consumers look for strategies that are successful on the internet. One example is the story that says that turning off the refrigerator at night is an energy-saving habit. It will be?

Thus, the refrigerator is designed to operate continuously in order to maintain a constant internal temperature. When it is turned off, the internal temperature starts to rise. When the refrigerator is turned on again, it has to work harder to cool the food and reach the ideal temperature.

On the contrary! This extra effort to compensate for the time off can result in an increase in energy consumption, resulting in an effect completely opposite to what was expected. For this reason, it is most recommended to leave the refrigerator on all the time to maintain a constant temperature and to save money energy in another way.
It is more useful to avoid opening the appliance door unless it is really necessary. This can result in much greater savings than this on/off switch. Other items in your home can be unplugged for real savings, such as speakers, microwaves and some others. In the case of the refrigerator, this is not a good idea!
