1. What is the Most Energy Efficient Refrigerator?
Energy efficiency is a measure of how well an appliance converts energy into the desired output. In this case, the output is the refrigeration of food and beverages. The most energy efficient refrigerator is one that consumes the least amount of energy while still performing its primary function effectively.
The most energy efficient refrigerators are those that have earned the ENERGY STAR® label. The ENERGY STAR program is a joint effort between the U.S. Environmental Protection Agency (EPA) and the U.S. Department of Energy (DOE). The label is awarded to appliances that meet or exceed energy efficiency guidelines established by the EPA.
To earn the ENERGY STAR label, refrigerators must be at least 20% more energy efficient than the minimum federal energy efficiency standards. These standards are set by the National Appliance Energy Conservation Act (NAECA). In addition, ENERGY STAR refrigerators must meet certain criteria related to features, such as automatic defrost, anti-sweat heaters, and high-efficiency compressors.
2. Best Energy Efficient Refrigerator Features
When selecting an energy efficient refrigerator, it is important to look for specific features that contribute to its energy efficiency. Here are some of the best energy efficient refrigerator features:
a. Size
The size of the refrigerator is an important consideration when it comes to energy efficiency. Generally, larger refrigerators consume more energy than smaller ones. Therefore, it is important to choose a refrigerator that is the right size for your household’s needs.
b. Compressor
The compressor is the heart of the refrigerator and is responsible for keeping the food cold. A high-efficiency compressor can significantly reduce energy consumption. Look for refrigerators with compressors that have a variable speed or a DC motor, as they are more energy efficient.
c. Insulation
The insulation in the refrigerator is another important feature that affects its energy efficiency. Refrigerators with thicker insulation keep the cold air inside and reduce the amount of energy required to maintain the desired temperature.
d. Lighting
The lighting in the refrigerator can also affect its energy efficiency. LED lighting is more energy efficient than traditional incandescent lighting, as it consumes less energy and generates less heat.
e. Automatic Defrost
Automatic defrost is a feature that prevents ice buildup in the refrigerator and freezer compartments. It also helps the refrigerator run more efficiently by keeping the evaporator coils clean.
f. Temperature Controls
Refrigerators with temperature controls allow you to adjust the temperature settings to your specific needs. This can help you save energy by not overcooling or overfreezing your food. Modern smart appliences provide more control including the ability to monitor and adjust the temperature remotely through a mobile app.
g. Door Features
The doors of the refrigerator can also affect its energy efficiency. Look for refrigerators with doors that seal tightly to prevent cold air from escaping. In addition, consider purchasing a refrigerator with a door alarm that alerts you if the door has been left open for too long.
3. How to Measure Refrigerator Efficiency
To measure refrigerator efficiency, you need to look at its energy consumption and compare it to its size and features. The most common way to measure refrigerator efficiency is by using the Energy Guide label.
The Energy Guide label is a yellow label that is required by law to be displayed on most appliances, including refrigerators. The label provides information on the estimated annual energy consumption of the refrigerator, as well as its size, features, and efficiency rating.
The efficiency rating is measured in kilowatt-hours per year (kWh/year) and is based on the estimated amount of energy the refrigerator will consume in one year of normal use. The lower the kWh/year number, the more energy efficient the refrigerator is.
In addition to the Energy Guide label, you can also look for the ENERGY STAR label. As previously mentioned, ENERGY STAR refrigerators are at least 20% more energy efficient than standard models. The ENERGY STAR label also provides information on the estimated annual energy consumption and efficiency rating of the refrigerator.
4. Cost Benefit Analysis of the Most Energy Efficient Refrigerator
While energy efficient refrigerators may have a higher initial cost, they can save you money in the long run through reduced energy bills. To determine the cost benefit of purchasing an energy efficient refrigerator, you can perform a cost benefit analysis.
A cost benefit analysis involves comparing the initial cost of the refrigerator to the estimated energy savings over its lifetime. To perform a cost benefit analysis, follow these steps:
- Determine the initial cost of the refrigerator.
- Estimate the annual energy consumption of the refrigerator using the Energy Guide label or ENERGY STAR label.
- Estimate the cost of energy per kilowatt-hour in your area.
- Calculate the estimated annual energy cost of the refrigerator by multiplying the annual energy consumption by the cost of energy per kilowatt-hour.
- Determine the expected lifetime of the refrigerator.
- Calculate the estimated lifetime energy cost of the refrigerator by multiplying the estimated annual energy cost by the expected lifetime of the refrigerator.
- Subtract the estimated lifetime energy cost from the initial cost of the refrigerator to determine the estimated lifetime savings.
For example, let’s say you are considering purchasing an energy efficient refrigerator that costs $1,000 and has an estimated annual energy consumption of 300 kWh/year. The cost of energy in your area is $0.15 per kilowatt-hour. The expected lifetime of the refrigerator is 15 years.
Using the steps above, you can calculate the estimated lifetime savings:
- Initial cost of refrigerator = $1,000
- Annual energy consumption = 300 kWh/year
- Cost of energy = $0.15 per kWh
- Estimated annual energy cost = 300 kWh/year x $0.15 per kWh = $45/year
- Expected lifetime of refrigerator = 15 years
- Estimated lifetime energy cost = $45/year x 15 years = $675
- Estimated lifetime savings = $1,000 – $675 = $325
In this example, the estimated lifetime savings from purchasing an energy efficient refrigerator are $325.
5. Pro Tips for Choosing the Best Energy Efficient Refrigerator
