Refrigerator Energy Calculator (Cost and kWh Usage)


When it comes to household appliances, the refrigerator is an essential one for many people. It helps to keep food fresh and prevents spoilage. However, like all appliances, it also consumes energy, and this energy consumption can add up over time. In this article, we’ll explore the energy consumption and costs of using a refrigerator, as well as provide some money-saving tips to help reduce your energy bill.


How To Use This Calculator

Using this energy calculator is a simple and will help you determine the costs of running your appliance. Click on ‘Calculate’ to use the predefined values, or enter your daily usage in hours, appliance watts, and your current energy costs in dollars. The calculator will provide you with the daily, monthly, and yearly results. It’s important to ensure the accuracy of the information entered to get the most accurate results.

Hours Used Per Day

Enter the number of hours you estimate the appliance will be on throughout the day. To use fractions of an hour please use a decimal point in the form.

For example: 1 hour and 30 mintes would be 1.5, and 3 hours and 15 minutes would be 3.25

Power Used in Watts

The calculator already includes a default average wattage. If your appliance uses a different wattage then enter it in the calculator.

Your Energy Rate in kWh

The calculator includes an average energy rate (price in $/kWh) to use for the calculation. This may not be the exact price that you’re currently paying for electricity. If you know your energy rate please enter your price per kilowatt-hour.

Energy Consumption

A refrigerator uses electricity to keep its contents cool. The amount of energy it uses depends on a few factors, including its size, age, and efficiency rating.

The most common measurement for energy consumption is watts (W) and kilowatts (kW). A watt is a unit of power equal to one joule per second, while a kilowatt is equal to 1,000 watts.

For example, if your refrigerator uses 100 watts, that means it consumes 0.1 kilowatts (kW) per hour. If you run it for 24 hours, that’s 2.4 kWh per day.

To put it into perspective, a refrigerator with a capacity of 18 cubic feet and an efficiency rating of 350 kWh per year will use approximately 0.96 kWh per day, or around 350 kWh per year.

Importance and Relevance

The energy consumption of refrigerators has become increasingly important in recent years due to the rising cost of electricity and concerns about energy consumption and environmental impact.

According to the US Department of Energy, refrigerators account for approximately 14% of the total energy usage in the average American home. This means that any reduction in energy usage can have a significant impact on your energy bills and carbon footprint.

By understanding the energy consumption of your refrigerator and implementing energy-saving tips, you can save money on your energy bills and reduce your carbon footprint.

Cost in Dollars of Energy Usage

The cost of running a refrigerator can be calculated using the following formula:

Cost = Power (kW) x Time (hours) x Price per kWh

Using our default values of 100 watts and an energy price of $0.12 per kWh, the cost of running a refrigerator for 24 hours is:

Cost = 0.1 kW x 24 hours x $0.12/kWh = $0.29 per day

For a month:

Cost = 0.1 kW x 720 hours (30 days x 24 hours) x $0.12/kWh = $8.64 per month

For a year:

Cost = 0.1 kW x 8760 hours (365 days x 24 hours) x $0.12/kWh = $105.12 per year

As you can see, the cost of running a refrigerator can add up quickly. However, by implementing some energy-saving tips, you can reduce your energy bills significantly.

Money Saving Tips

Here are some money-saving tips for your refrigerator:

  • Keep your refrigerator full: A full refrigerator doesn’t have to work as hard to maintain a cool temperature. If your fridge is empty, fill it with jugs of water or other non-perishable items.
  • Clean the coils: Dust and debris can accumulate on the refrigerator coils and make it work harder. Clean them regularly to improve efficiency.
  • Don’t overfill the fridge: Overfilling the fridge can cause it to work harder to maintain a cool temperature. Keep the fridge at a reasonable capacity.
  • Check the temperature: The temperature of the fridge should be set at 37-40 degrees Fahrenheit and the freezer at 0-5 degrees Fahrenheit.
  • Keep the door closed: Every time you open the fridge, cold air escapes, and warm air enters. Keep the door closed as much as possible to maintain the temperature.

By implementing these tips, you can reduce your energy consumption and save money on your energy bills. It’s a win-win situation!

In conclusion, understanding the energy consumption and cost of using a refrigerator can help you make informed decisions about your energy usage. By implementing energy-saving tips and being mindful of your usage, you can reduce your carbon footprint and keep your energy bills in check.
