# Dorm Size Refrigerator Energy Calculator (Cost and kWh Usage)

Dorm size refrigerators are a common sight in many college dorm rooms, apartments, and small living spaces. These compact appliances are convenient for storing food and beverages, but they can also consume a significant amount of energy. In this article, we will dive into the energy consumption and costs of using a dorm size refrigerator and provide tips for saving money while using this appliance.

## 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

The energy consumption of a dorm size refrigerator is measured in watts. The default provided for this article is 350 watts. This means that if the refrigerator is left running for one hour, it will consume 350 watt-hours (Wh) of energy. To put this into perspective, if the refrigerator were to run for 24 hours, it would consume 8.4 kilowatt-hours (kWh) of energy in a day, based on the default wattage.

It’s important to note that the actual energy consumption of a dorm size refrigerator may vary depending on factors such as the age and condition of the appliance, ambient temperature, and the frequency of door openings.

## Importance and Relevance

Understanding the energy consumption of appliances like dorm size refrigerators is important for several reasons. First and foremost, it can help consumers make informed decisions about which appliances to purchase. By choosing an energy-efficient model, consumers can save money on their energy bills and reduce their carbon footprint.

In addition, reducing energy consumption overall is a critical step in combatting climate change. According to the U.S. Environmental Protection Agency, appliances and electronics account for roughly 30% of household energy use. By making small changes in our daily lives, such as unplugging appliances when not in use, we can collectively reduce our impact on the environment.

## Cost in Dollars of Energy Usage

To calculate the cost of using a dorm size refrigerator, we need to know both the energy consumption in kWh and the cost of electricity per kWh. The default cost provided for this article is \$0.12 per kWh.

Using the default wattage of 350 watts, we can calculate that the refrigerator consumes 8.4 kWh of energy in a day. To calculate the daily cost, we simply multiply 8.4 kWh by \$0.12, which equals \$1.01. Multiply this by 30 for the monthly cost, which equals \$30.24. For the yearly cost, multiply the daily cost by 365, which equals \$367.92.

It’s important to note that the actual cost of energy usage will vary depending on the cost of electricity in your area and the actual energy consumption of your refrigerator. However, using the formula provided above can give you a rough estimate of your annual energy costs.

## Money Saving Tips

There are several ways to reduce the energy consumption and associated costs of using a dorm-size refrigerator. Here are some tips:

• Set the temperature to the recommended level for your refrigerator (between 35-38 degrees Fahrenheit) to avoid unnecessary energy consumption.
• Keep the refrigerator door closed as much as possible to prevent cold air from escaping.
• Regularly defrost the appliance to ensure it is running efficiently.
• Make sure the refrigerator is placed in a cool, well-ventilated area to prevent it from working harder than necessary.
• Consider purchasing an energy-efficient model that is certified by ENERGY STAR. These models typically use 10-15% less energy than standard models.

By following these money-saving tips, you can reduce your energy consumption and save money on your energy bills. Not only will this be good for your wallet, but it will also benefit the environment by reducing your carbon footprint.

In conclusion, dorm-size refrigerators provide a convenient way to store food and beverages, but they can also consume a significant amount of energy. Understanding energy consumption and associated costs can help consumers make informed decisions about which appliances to purchase and take steps to reduce their impact on the environment. By following the money-saving tips provided in this article, you can enjoy the benefits of a dorm-size refrigerator while minimizing its impact on your wallet and the planet.
