1. Air Fryers: Crisp Results, Minimal Power

Try: Ninja AF101 Air Fryer, 4 Qt, Crisping Technology

Air fryers cook food faster and use significantly less energy than a full-size oven. They’re efficient for small meals, reheating leftovers, and even baking, all while staying cool, making them a win in the summer.

2. Single-Serve Coffee Makers: Easy, but Wasteful?

Try: Keurig K-Mini Plus Single Serve Coffee Maker

While they use less electricity per brew, single-serve machines can waste more resources if used multiple times a day. To offset this, choose one with an auto-off feature and use refillable pods to reduce waste.

3. Electric Kettles: Small Appliance, Big Savings

Try: COSORI Electric Kettle with Stainless Steel Filter and Auto Shut-Off

Boiling water in an electric kettle is faster and more energy-efficient than using a stovetop, especially for tea or instant meals. Just make sure to only boil the amount of water you need to save even more.

4. Robotic Vacuums: Time-Saving, but Always Charging

Try: eufy by Anker, RoboVac G30

These are game-changers for busy households, but standby power can add up. Look for models with smart scheduling and energy-efficient navigation to reduce unnecessary cycles and energy drain.

5. Toaster Ovens: Smart Swap for the Big Oven

Try: Breville Mini Smart Toaster Oven with Element IQ

Toaster ovens are ideal for small baking and roasting tasks. They preheat quickly and use less electricity, making them a great energy-saving alternative to your full-sized range.

6. Countertop Dishwashers: Compact but Consuming?

Try: COMFEE’ Portable Countertop Dishwasher with 6 Programs

These models are perfect for small kitchens and renters, and they often use less water than handwashing. To reduce energy use, always run them full and use the eco-mode when available.

7. Electric Food Processors: Time Saver for Home Cooks

Try: Hamilton Beach 10-Cup Food Processor & Vegetable Chopper

If you cook from scratch, this tool cuts down meal prep significantly. Although it uses energy, it reduces the temptation to buy processed, packaged (and more resource-heavy) alternatives.

8. Mini Fridges: Handy, but Energy-Thirsty

Try: BLACK+DECKER Compact Mini Fridge with Freezer

Mini fridges are great for dorms, offices, or drink storage, but cheap models can be energy hogs. Choose one that’s Energy Star certified and unplug it when not in use for maximum savings.

9. Microwaves: Quick Heating, Low Consumption

Try: Toshiba EM131A5C-BS Microwave Oven with Smart Sensor

Despite their convenience, microwaves are surprisingly energy-efficient, especially for reheating or cooking small portions. Just avoid using them for large meals better suited to an oven or slow cooker.

10. Multi-Cookers: One Pot, Many Jobs

Try: Instant Pot Pro 10-in-1, 8 Quart Pressure Cooker

A multi-cooker can replace several appliances—slow cooker, rice maker, steamer, and more—saving space and power in the long run. It uses energy smartly and minimizes heat output in the kitchen.
