Set the temperature of your refrigerator
One of the basic principles for food preservation is to store it at a suitable temperature. This should be between 3 and 5 degrees. This means that food spoils more slowly.
Remember that your fridge accounts for 30.6% of the electricity used by your appliances. To cut your bill and ensure efficiency, be sure to close the door properly. Every time you leave the door open the cold escapes... and you also add a few euros to your your bill to cool things down again.
Remember that A+++ refrigerators are the most efficient and can save up to 80% in energy consumption compared to refrigerators with lower energy efficiency labels. In addition, they are more environmentally friendly, and will emit one and a half tons less CO2 during their useful lives.
