Yes, an air fryer generally uses more electricity per use than a microwave because it cooks with intense heat for longer periods (often 15-30 mins) using powerful heating elements (800-2000W), whereas a microwave cooks food much faster (minutes) with radiation, making microwaves more energy-efficient for reheating and short tasks, even if their wattage seems similar.
An air fryer is usually more expensive to run than a microwave. They typically have similar power ratings, but microwaves cook food much more quickly than air fryers.
People are getting rid of air fryers due to small basket sizes limiting family meals, issues with peeling non-stick coatings, difficulty cleaning, safety concerns like melting components, the perception they're just small ovens, limitations on certain foods (like wet batters), and sometimes switching to cheaper, more efficient appliances like halogen ovens. Many find they outgrow basic models, leading to batch cooking, and eventually replace them with larger or different appliances.
Heating and cooling (HVAC) typically runs up an electric bill the most, often accounting for around 40% of energy usage, followed by water heating, large appliances like refrigerators and clothes dryers, and lighting. The biggest energy drains are systems that change air temperature (furnaces, air conditioners) and appliances that heat water (showers, dishwashers) or run for extended periods (dryers, fridges).
Air fryer disadvantages include limited capacity (requiring batch cooking), taking up valuable counter space, a learning curve for even cooking (needing shakes/turns), potential formation of harmful compounds like acrylamide if food is charred, issues with cooking wet batters, and concerns over non-stick coating safety (PTFE). They also can't perfectly replicate deep-fried taste and may be noisy.
Air-frying equipment is not known to cause cancer, but the process of air frying does result in the formation of certain compounds, like acrylamide, that are linked to cancer development. Acrylamide is classified as a probable human carcinogen.
But here's the bit I wish I'd known – air fryers aren't always the cheapest option to run. It all depends on what you're cooking and the wattage of your machine. Do the same dish twice in a small 800W air fryer and you could actually spend more than if you'd just used the oven.
Microwaves, coffeemakers, toasters, and electric kettles often have clocks, digital displays, or sensors that remain active even when the appliances aren't being used. These features, while handy, drain energy continuously.
Here's what uses the most energy in your home:
Did you know that when your appliances or electronic devices are plugged in, they're draining energy – even if they're not in use? Phantom power, also called standby power, refers to the energy that's wasted around your home when devices are plugged in and using power, but you're not actively using them.
Air Fryers Reduce Taste Quality
Out of the top three reasons restaurants don't use air fryers, the taste is the leading cause. It has numerous benefits and can cook food efficiently. However, the taste can be subpar compared to other cooking methods available at the commercial level.
The "air fryer rule of 25" is a handy guideline for converting oven recipes: reduce the oven temperature by 25°F (or 10-20°C) and decrease the cooking time by about 20-25%, checking for doneness earlier. This rule works because air fryers cook faster and more intensely than conventional ovens, circulating hot air efficiently to crisp food quickly, so you often need less time and slightly lower heat.
It's not just about fat.
There's more to air fryers than calories and crunch. Cooking with less oil also reduces acrylamide, a potentially harmful chemical that forms in starchy foods when they're cooked at high temperatures. “Air frying has been shown to lower acrylamide levels compared to deep frying,” says Dr.
5 Common Mistakes to Avoid When Using an Air Fryer
Choose energy-saving appliances
Switching up the appliances you use can have a big impact on your energy consumption. Microwaves, slow cookers, and air fryers all use less energy than a traditional oven, making them a great option for low-maintenance, low-cost, and low-carbon cooking.
There's no universal winner between a microwave and air fryer; it comes down to your habits, preferences, and space. If you need quick reheating and energy-efficient cooking, a microwave delivers on all fronts. If you're after texture, crunch, and fry-like results without the oil, an air fryer will likely impress.

1. Tumble dryer. If you have a large household, laundry is likely to be a time-consuming task that tumble dryers can speed up considerably, but they are also one of the biggest energy-sapping appliances in our homes. The type of tumble dryer you have makes a huge difference to how much it costs you to run.

8 Appliances You Should Always Unplug When You're Not Using Them
Here are the five worst appliances to keep on standby - by turning these off you could save up to £75 a year.
Switch your kettle off at the wall when not in use
Does leaving a kettle plugged in use electricity? Yes. And while this won't add up to riches, making sure your kettle is turned off at the plug can help you save some pennies.
The "Air Fryer 20/20 Rule" is a guideline for converting conventional oven recipes, suggesting you reduce the cooking time by 20% and lower the temperature by 20°C (or about 20°F) to account for the air fryer's faster, more intense cooking. While a good starting point, it's essential to monitor your food and potentially shake or flip it halfway through for even cooking, as air fryer models and foods vary, notes this BBC article.
The arduous cleanup kind of negates the saved cooking time
Many oven-based recipes cook 20% faster in an air fryer. Of course, you also have to clean the air fryer, and it's a bit higher maintenance than an oven or even a toaster oven.
