How to find the best refrigerator for energy efficiency?
What to Look For
Start with ENERGY STAR certification. In the U.S., ENERGY STAR refrigerators use about 10% less energy than standard models, and often more. The yellow EnergyGuide label lists estimated annual electricity use in kilowatt-hours (kWh) and cost. Compare that number across models—lower is better.
Size and style matter. Top-freezer refrigerators are generally the most energy-efficient, followed by bottom-freezer, side-by-side, and French-door models. Larger refrigerators use more energy, so buy the size you need, not the biggest one that fits. For a typical household, 18–22 cubic feet is often enough.
Features like through-the-door ice and water dispensers increase energy use by 10–20% because they add heating elements and extra components. If efficiency is your top priority, skip the dispenser.
- ENERGY STAR certified: Meets strict efficiency guidelines.
- EnergyGuide label: Shows estimated yearly kWh and cost.
- Top-freezer: Most efficient style.
- Right size: 18–22 cu. ft. for many households.
- Skip dispensers: They raise energy use.
How to Compare Models
Use the EnergyGuide label to compare annual kWh. For example, a typical 18 cu. ft. top-freezer might use around 350–400 kWh per year, while a larger French-door with dispenser could use 600–700 kWh. Multiply kWh by your local electricity rate to estimate yearly cost.
Check for advanced features that improve efficiency, such as inverter compressors, dual evaporators, and improved insulation. These can reduce energy use without sacrificing performance. Some models also have an 'eco' mode that slightly raises the fridge temperature and lowers energy use.
Read professional reviews and user ratings for reliability, but remember that energy efficiency is separate from overall quality. A reliable fridge that uses more energy may cost more over time.
- Compare kWh: Lower annual use means lower bills.
- Inverter compressor: More efficient and quieter.
- Dual evaporators: Better humidity control, less energy waste.
- Eco mode: Saves energy when you don't need maximum cooling.
- Check rebates: Utilities may offer incentives for efficient models.
Common mistakes
- Assuming a smaller fridge is always more efficient—a poorly insulated small model can use more than a well-designed larger one.
- Ignoring the EnergyGuide label and guessing based on price or brand.
- Placing the fridge next to a heat source (oven, direct sun) which makes it work harder and use more energy.
