Energy Efficiency: Is Your Old Refrigerator Costing You Money?

It’s 2024 and you might be wondering if that old refrigerator in your kitchen is costing you more than it should in comparison to running a much newer model? Well, it probably is! Older models tend to be less energy-efficient, leading to higher electricity bills. In fact, just by replacing an old refrigerator that runs 24/7 you could save $100’s per year.

Energy-efficient refrigerators not only reduce your energy consumption but also lower your utility bills. Upgrading can save you a significant amount of money in the long run. Another clear benefit being that you get the new features that come along with a brand new appliance.

Understanding Refrigerator Energy Consumption

Your refrigerator is one of the most essential appliances in your home, I’m sure that you’ve wondered how it uses energy and what affects its efficiency?

How Refrigerators Use Energy

Refrigerators work by transferring heat from the inside of the unit to the outside, keeping your food cold and fresh. They use a system of coils, a compressor, and refrigerant to achieve this. Here’s a breakdown of their main energy use:

  • Compressor: This is the motor that pumps refrigerant through the coils. It cycles on and off to maintain the set temperature.
  • Coils: The evaporator and condenser coils transfer heat out of the fridge. Evaporator coils absorb heat from inside the fridge, while condenser coils release it outside. They are usually located at the back of the fridge.
  • Thermostat: The thermostat monitors the temperature inside the fridge and tells the compressor when to turn on and off.

The energy consumption of a refrigerator is typically measured in kilowatt-hours (kWh) per year. According to EnergySage, most standard-sized refrigerators use between 300 to 800 watts, but the running wattage is generally lower as the fridge will use most electricity when the temperature rises above the set level.

If any of these key components are failing or in need of repair it can cause your energy bill to be higher than necessary because of an inefficient refrigerator.

Factors Affecting Refrigerator Energy Costs

Several factors influence how much energy your refrigerator consumes:

  1. Age of the Appliance: Older refrigerators are generally less energy-efficient than newer models. Modern, energy-efficient fridges can save significant energy and money over their lifespan.
  2. Thermostat Settings: Setting your fridge to a very cold temperature can cause it to use more energy because it will cycle on and off more regularly. The ideal temperature is between 35°F and 38°F for the fridge, and 0°F for the freezer.
  3. Ambient Temperature: If your refrigerator is in a hot environment, like near an oven or in direct sunlight, it will have to work harder to stay cool. NOPEC notes that fridges on average account for 13% of household electricity; its location can impact energy usage.
  4. Opening the Door Frequently: Frequently opening the door or leaving it open for extended periods lets cold air out and warm air in, making the fridge work harder to maintain the set temperature.
  5. Maintenance: Regular maintenance, such as cleaning the coils and inside the fridge/freezer, checking the door seals, can all improve efficiency. Properly maintaining your fridge can also increase its lifespan and potential repair costs.
  6. Refrigerant Type: The type and amount of refrigerant in your fridge also affects its efficiency. Some refrigerants are more efficient and safer than others, particularly newer gasses.
  7. Size and Capacity: Larger refrigerators generally use more energy than smaller ones, although it all depends on which model of fridge we are talking about, 2 fridges the same size can be drastically different in the amount of energy they need.

Keeping these factors in mind can help you optimize the energy efficiency of your refrigerator and save on your electricity bill.

Understanding these aspects can help you make informed decisions, whether you want to maintain your current refrigerator or consider an upgrade to a more energy-efficient model.

Calculating the Cost of Running an Old Refrigerator
