No. Modern fridges span the entire spectrum of energy efficiency, from highly efficient to heavy power consumers. Because scales have been updated (like the A-to-G rating) to reflect modern technology, many average fridges sit in the middle, while highly engineered models—like ENERGY STAR Certified Refrigerators—offer top-tier savings.
Checking the energy label before you buy a product gives you an idea of how expensive it will be to run. An appliance with a low energy rating is less efficient than one with a high rating.
Top-freezer refrigerators are typically the most energy-efficient standard option. Because of their simpler design, natural airflow, and lack of complex door features, they consume 10% to 25% less electricity than side-by-side or bottom-freezer models.
Heating and cooling systems (HVAC)—such as central air conditioning and electric furnaces—use the most electricity in a home, accounting for about 40% to 50% of your total energy consumption.
There is no single "most efficient" brand, as efficiency depends heavily on the specific style and capacity of the unit. However, LG, Samsung, GE, and Frigidaire frequently produce top-rated models that earn the ENERGY STAR Most Efficient designation.
The Top Energy-Draining Appliance: Space Heating & Cooling
This includes both forced-air systems, heat pumps, furnaces, baseboards, window A/C units, and fans. Because they run for long periods and often at high wattage, they dominate the consumption profile.
In general, French door refrigerators offer more fresh food storage that is easy to customize to your needs, while side-by-side refrigerators provide more freezer space and door storage at a lower price point.
In most homes, Heating and Cooling (HVAC) systems drive the highest energy costs, accounting for nearly 40% to 50% of your total electricity bill. Following these, the appliances that run up your bill the most include water heaters, refrigerators, and laundry machines.
Many folks go by the 50-50 rule. If the appliance has reached 50 percent of its expected life and it costs more than 50 percent of the cost of new, buy a new one. Oven failures can start with underperformance. For example, a family favorite just doesn't come out like it used to.
Yes. Leaving a TV plugged in uses electricity even when it is turned off. This continuous trickle of energy is known as "phantom load" or "vampire power".
Avoid external water/ice dispensers and "smart" screens. These features add unnecessary complexity and are leading failure points across major appliance brands. Additionally, never buy a fridge without mapping your space—measure both the installation nook (including hinge/door clearances) and your home’s entryways (hallways, doorways).
Without modern electricity, the Amish keep food cold using propane-powered appliances, insulated ice houses, and traditional root cellars. By adapting to their religious and community guidelines, they successfully preserve food year-round.
Top-Freezer Refrigerators
Top-freezer models are generally the most energy-efficient option on the market.
The top 5 worst appliances to leave on standby
Electric heating systems and tumble dryers tend to be the most expensive electrical items to run because they use large amounts of power over extended periods. Other high-cost appliances include electric ovens and immersion heaters.
To choose a good refrigerator, measure your space accurately first—allowing 1 inch of clearance on all sides—and select a style that fits your layout, such as a French door, side-by-side, or top freezer. Prioritize energy efficiency by checking the EnergyGuide label, and avoid overpaying for complex smart features that are prone to breaking.
Holiday Sale Periods (May, September, and November)
Certain holidays have become synonymous with appliance discounts, and for good reason. Many shoppers wait for these times to make big purchases, and retailers respond with competitive pricing across most major brands.
Your heating and cooling system is by far the biggest energy consumer in your home. Air conditioners, furnaces, and heat pump HVAC systems work hard to keep your home comfortable year-round, but they also account for almost half of your energy bill.
Small appliances with the shortest lifespan typically include kitchen appliances like toasters, blenders, and coffee makers. These tend to have more limited warranties and are generally less durable compared to larger household appliances like refrigerators or washing machines.
The fix: Lower your home temperature to 68 degrees when you're home. Maintain comfort by adding extra layers of clothing – try fabrics like fleece, flannel and wool – and don't forget comfy slippers and blankets. If you can comfortably go a degree or two cooler than 68, your wallet will benefit even more!
Yes, unplugging appliances does save energy. According to the U.S. Department of Energy, standby or "phantom" power accounts for 5% to 10% of residential energy use, costing average households $100 to $200 annually.
The Amish generally use propane (gas) refrigerators, solar-powered appliances, or traditional iceboxes stocked with harvested pond ice. Because their Ordnung (community rules) forbid direct connection to the public electrical grid, they rely on alternative energy and low-tech cooling solutions to keep food fresh.
There is no single "number one" refrigerator brand, as the best option depends on your priorities. However, industry experts and consumer testing currently highlight three top brands:
The best times to buy a refrigerator at Costco are May, Labor Day, and Black Friday. During these peak periods, Costco runs aggressive "Appliance Savings Events", often offering bundle discounts, significant price markdowns, and bundled perks like free delivery, haul-away of your old unit, and extended warranties.
