In the quiet corners of South African kitchens, a silent revolution is humming—not with the roar of generators or the flicker of load-shedding alerts, but with the soft whir of a countertop appliance that has turn into both a lifeline and a lightning rod in the national conversation about energy. Air fryers, once dismissed as a fleeting kitchen trend, are now being scrutinized not just for their ability to crisp fries without oil, but for their potential to reshape household electricity consumption in a country where every kilowatt-hour carries economic and emotional weight.
The question isn’t merely technical—it’s deeply personal. For millions of South Africans navigating Stage 6 load-shedding, rising tariffs, and the slow burn of economic uncertainty, the air fryer represents more than convenience. It promises agency: the ability to cook a meal without waiting for the grid to breathe. But does it truly save electricity? Or is it just another appliance adding to the silent drain on already strained household budgets?
To answer this, we must look beyond the marketing claims and into the real-world patterns of use, the hidden costs of standby power, and the broader energy ecosystem that shapes how South Africans live, cook, and cope.
The Myth of the “Always-Off” Appliance
At first glance, the math seems straightforward: an air fryer typically draws 1,400 to 1,800 watts during operation, compared to a conventional oven’s 2,000 to 5,000 watts. Used for 20 minutes to cook chicken wings or roast vegetables, it undeniably consumes less energy than preheating a full-sized oven for the same task. Studies by the Energy Research Centre at the University of Cape Town confirm that for small-volume cooking, air fryers can reduce energy use by 30–50% per meal.
But here’s the gap the headlines miss: usage frequency. A 2025 survey by the South African Appliance Retailers Council found that 68% of air fryer owners use their device daily—or even multiple times a day—often replacing not just oven use, but stovetop cooking, microwaving, and even takeaway orders. What began as a tool for occasional crisping has become a primary cooking method.
“People aren’t just swapping one appliance for another,” said Dr. Lerato Mokoena, senior energy analyst at the Council for Scientific and Industrial Research (CSIR), in a recent interview. “They’re changing their entire cooking rhythm. If you’re using your air fryer three times a day for 15 minutes each, you’re not saving energy—you’re shifting the load, and in some cases, increasing total daily consumption.”
“The real issue isn’t the appliance’s wattage—it’s behavioral adaptation. When something becomes easier, we use it more. In energy terms, that’s called the rebound effect, and it’s real in South African kitchens.”

The Hidden Drain: Standby Power and the Phantom Load
Another overlooked factor is standby power. Unlike older appliances that truly shut off, many modern air fryers—especially those with digital touchscreens, Wi-Fi connectivity, or preset menus—draw between 0.5 and 3 watts continuously, even when “off.” In a household with multiple smart devices, this phantom load accumulates.
Research from the National Regulator for Compulsory Specifications (NRCS) indicates that the average South African home now has 12–15 devices drawing standby power, collectively accounting for 5–10% of total household electricity use. An air fryer left plugged in 24/7 could add as much as 26 kWh annually—equivalent to running a 60-watt LED bulb for over 430 hours.
“We’re seeing a quiet creep of energy use,” noted Thandiwe Ndlovu, head of consumer energy efficiency at Eskom’s Demand Side Management division. “It’s not dramatic like a geyser or stove, but when you multiply it by millions of homes, it becomes a measurable strain on the grid—especially during peak evening hours when air fryers are most commonly used.”
“Consumers think ‘unplugging’ is obsolete. But in a country where every watt counts, the simplest act—pulling the plug after use—can save more than switching to a more efficient model.”

Beyond the Watt: The Socioeconomic Ripple
The air fryer’s impact extends beyond the meter. In townships and informal settlements where access to reliable electricity is intermittent, the appliance has become a symbol of resilience. For families relying on prepaid meters, the ability to cook a nutritious meal quickly during brief power windows reduces reliance on expensive, unhealthy alternatives like vetkoek or fried street food.
Yet this same accessibility brings equity concerns. A 2024 study by UCT’s Poverty and Inequality Initiative found that whereas air fryer ownership has surged across income groups, usage patterns diverge sharply. In higher-income suburbs, they’re often secondary gadgets—used for convenience. In lower-income households, they’re primary tools—sometimes the only reliable cooking device when the grid fails.
This duality reveals a deeper truth: energy efficiency isn’t just about technology. It’s about access, behavior, and context. An air fryer saves electricity only if it replaces a more energy-intensive method—and only if it’s not left drawing power 24/7.
The Takeaway: Wisdom Over Wattage
So, do air fryers really save electricity? The answer, as with so many things in modern life, is: It depends.
They save energy when used mindfully—for small batches, replacing oven use, and unplugged after each session. They become energy liabilities when used excessively, left on standby, or treated as a justification for cooking more, more often.
For South Africans navigating an energy landscape defined by scarcity and innovation, the lesson isn’t to reject the air fryer—it’s to reclaim agency over how we use it. Measure your meals. Unplug the device. Cook with intention, not just convenience.
The most powerful appliance in your kitchen isn’t the one on the counter. It’s the habit you build around it.
What’s one small change you’ve made in your kitchen to save energy—and did it surprise you how much it mattered?
