Gas, induction, air fryer or microwave: What really saves money in your kitchen?

There was a time when moving from smoky firewood stoves to LPG felt like a clean, modern upgrade. Today, the shift is happening all over again. Induction cooktops, air fryers and microwave ovens are quietly taking their place beside the gas stove. But when it comes to everyday cooking, which one actually saves you more money. Gas or electricity?

LPG gas stove
For most Kerala kitchens, the gas stove still feels like home. It works with any kind of vessel, handles everything from slow curries to high-heat frying, and keeps going even during a power cut. That reliability is hard to beat.

The downside is the cost. LPG prices keep climbing, and gas cooking is not as efficient as it looks. Nearly half the heat escapes into the kitchen instead of reaching the vessel. That is why the room heats up so quickly when you cook on gas.

Induction cooktop
Among electric options, induction stands out for sheer efficiency. It uses magnetic technology to heat only the vessel, not the surrounding air. Very little energy is wasted, which makes it faster and surprisingly economical for daily tasks.

Boiling water, making tea or cooking simple dishes can cost much less on induction compared to gas. The kitchen stays cooler too, which is a small but real comfort.

There are limitations. You need flat, induction-compatible cookware. And yes, your electricity bill may go up a bit. But when you compare it with the price of LPG refills, induction often works out cheaper.

Air fryer
For a cuisine that loves fried fish and chicken, cutting down on oil is not easy. That is where the air fryer fits in. It uses very little oil and still delivers crisp results.

It also saves time and energy compared to deep frying on gas. Snacks like cutlets, French fries, chicken and fish turn out well with less effort.

But it is not built for everything. You cannot cook large quantities in one go, and it does not suit gravy-based dishes or traditional recipes.

Microwave oven
The microwave is less about cooking from scratch and more about convenience. It is perfect for reheating leftovers in seconds.

Compared to reheating on a gas stove, microwaves retain nutrients better and use energy more efficiently. But they do not replace traditional cooking methods. You are not going to make puttu or appam in a microwave.

Add solar and the equation changes
Kerala gets good sunlight for a large part of the year, and more homes are turning to solar panels. For a typical family, solar power can take a big chunk of cooking onto electricity without the worry of rising bills.

If you shift daytime cooking to induction and use appliances like the air fryer on solar power, the cost advantage becomes even clearer. What was once the biggest drawback of electric cooking, the electricity bill, almost disappears.

So what is the smartest choice
There is no single winner here. In a Kerala kitchen, relying on just one method is rarely practical. The real savings come from using a smart combination.

Use induction for boiling water, heating milk and making simple curries. Bring in the air fryer for frying and roasting with less oil. Keep the gas stove for dishes that need open flame, like fish curry, dosa or appam.

Split your cooking this way and you will notice the difference. Your gas cylinder lasts longer, your kitchen stays cooler, and your overall cooking cost comes down without changing what you eat.
