10 Best Energy Efficient Microwave 2026 in the United States

The Toshiba ML-EM62P(SS) is a large countertop microwave offering a roomy 2.2 cubic feet capacity, which easily fits bigger dishes like a 16-inch pizza or whole chicken—great for families or meal prepping. It runs at 1200 watts, providing strong cooking power for most kitchen needs. One of its standout features is the built-in humidity sensor with 6 automatic preset menus that help cook food evenly while keeping moisture locked in, which improves taste and texture without guesswork. The sensor-based cooking also supports an auto-defrost function tailored for meat, poultry, and fish, making thawing safer and more efficient.

Additionally, the microwave includes an eco mode to save energy and a mute option to reduce noise, which contribute to its energy-efficient appeal. The position memory turntable is a nice touch, ensuring food heats consistently by remembering the rotation spots. This model does not use inverter technology—a feature found in some other energy-efficient microwaves that provides more precise power control and can further save energy. It is quite heavy at nearly 50 pounds and takes up a sizeable counter space (almost 20 by 24 inches), so it's best suited for kitchens with enough room.

The stainless steel finish looks sleek and modern but might require regular cleaning to keep its shine. With simple controls and useful presets like bacon, beverages, and oatmeal, this microwave suits users who prefer convenience without complicated settings. If you are looking for a reliable, spacious microwave with smart sensor cooking and energy-saving options, the Toshiba ML-EM62P(SS) is a strong candidate, especially if inverter technology is not a must-have.

The Breville BMO870BST is a versatile 3-in-1 countertop appliance combining a microwave, air fryer, and convection oven in one, which can be a great space saver for kitchens. It has a 1.1 cubic feet capacity, suitable for everyday family use without being too bulky. With 1200 watts microwave power and 1400 watts for convection, it offers plenty of cooking strength, yet its inverter technology (called Power Smoothing Inverter) ensures the microwave power adjusts smoothly and evenly. This helps to cook or defrost food gently, avoiding hot spots or overcooked edges, which also saves energy by being more efficient.

It also has sensor cooking with 19 smart presets including defrost, reheat, and cook-from-frozen options, making it easy to get consistent results without guessing times or power levels. The Element IQ system intelligently manages power between air frying, baking, and microwaving, adding to efficiency and better food texture, especially for crispiness. The quieter operation and soft-close door add convenience and a premium feel.

On the downside, its 1200-watt power level is standard rather than low, so it’s not the lowest energy user in its category. Also, it’s a bit heavy at 45 pounds and fairly large, so it requires a good-sized countertop spot. The price and features suit those who want a multi-functional appliance with smart cooking aids rather than just a basic microwave. If you want a single device to replace multiple kitchen tools and appreciate gentle, sensor-controlled cooking, this model is a solid pick. However, if you mainly want the lowest energy microwave, simpler models might weigh less on electricity use.

The COMFEE' EM720CPL-PM Countertop Microwave Oven is an energy-efficient choice for small kitchens or dorm rooms, thanks to its compact size of 0.7 cu ft and 700 watts of cooking power. It features inverter technology and sensor cooking, which helps cook food evenly and efficiently. The microwave’s ECO Mode is a great addition for energy savings, reducing standby power consumption by 50%. Another notable feature is the mute function, allowing you to cook without the beeps, which can be particularly useful in quiet environments.

The two-step child lock adds safety, making it a family-friendly option. Additionally, it has easy one-touch buttons for common cooking tasks like popcorn and pizza, along with defrost settings by weight or time, making it user-friendly for quick meals. Despite these advantages, its smaller capacity might not be sufficient for larger families or those who cook large meals regularly. The wattage, while adequate, is on the lower end, which means it might take longer to cook or reheat food compared to higher-wattage models.

Its simple design and basic white color may not appeal to those looking for a more stylish kitchen appliance. However, it is a reliable and popular choice for those needing a compact, efficient microwave. This microwave is best suited for individuals or small households that prioritize energy efficiency and easy operation.
