Want to keep your electricity bill low? This is how a full fridge will help you

Stretching your monthly token purchase usually means switching off lights and limiting heavy kitchen appliances.
However, your refrigerator runs continuously, and its daily power use depends heavily on what sits on its shelves.
Running a fridge that is mostly empty forces the compressor to work twice as hard compared to one packed with food and chilled liquids.
How chilled food keeps temperature stable
The main reason comes down to how air and solid objects hold cold temperatures. Air warms up fast. Whenever you open the fridge door, cold air spills out into your kitchen and warm room air rushes in. The cooling compressor then has to work hard to bring that fresh warm air back down to temperature.
Chilled liquids and solid foods act differently. They store cold temperatures far better than air.
When your fridge contains items like water bottles, vegetables, and cooked food, these items act as a cold anchor. Less warm air can get inside because chilled items take up the space.
In a peer-reviewed study published in the journal Energies, researchers verified that “the thermal load and the room temperature have a significant influence on the energy performance of the refrigerator.”
When chilled items keep the internal temperature steady, the motor turns on less often and stays on for shorter periods.
Simple ways to fill space without buying extra food
You do not need to buy extra groceries just to pack your shelves. You can easily get the same result using tap water.
Filling empty spots with reusable plastic bottles or jugs full of water creates a cooling block. As the water chills, it absorbs heat whenever the door opens.
However, avoid cramming shelves so tightly that air cannot move around. Air needs space to circulate so the fridge cools evenly. Leaving a small gap of two or three inches between items keeps cold air flowing properly.
Making sure your door rubber seals close tightly also prevents cold air from leaking, helping your electricity token purchases last longer.
