Short answer: induction is the most efficient way to cook: about 85% of the energy reaches the pan, versus about 75-80% for standard electric and about 32% for gas, according to ENERGY STAR. It’s fast and keeps combustion pollutants out of your kitchen. Running cost differences are small; the bigger factors are the upfront price, cookware and air quality.
Efficiency compared
| Cooktop | Share of energy reaching the food |
|---|---|
| Induction | about 85% |
| Electric resistance (coil or smooth top) | about 75-80% |
| Gas | about 32% |
ENERGY STAR says induction is about 5-10% more efficient than standard electric and roughly three times more efficient than gas. Because the heat is made in the pan itself, the cooktop surface stays relatively cool and less heat escapes into the kitchen.
Running costs
Cooking is a small part of most energy bills, so switching rarely saves more than a modest amount each year. Whether gas or induction is cheaper to run depends on your local gas and electricity prices. Don’t switch for the bill savings alone; switch for speed, control, cleaning and air quality.
Air quality: what the research says
A 2025 U.S. Government Accountability Office report found that studies show gas stove emissions of nitrogen dioxide can exceed the EPA’s outdoor and the WHO’s 1-hour limits, and nitrogen dioxide has been linked to childhood asthma, though the GAO says the debate over health risks is ongoing. The GAO also found ventilation that sends emissions outdoors is one of the best ways to reduce them, as reported by ConsumerAffairs.
If you keep gas: use a range hood vented outdoors every time you cook, cook on back burners, and open a window when you can.
Induction pros and cons
| Pros | Cons |
|---|---|
| Very fast boiling and precise control | Needs magnetic cookware (cast iron, most stainless steel) |
| Cooler surface, easier cleanup | Higher upfront price than basic electric or gas ranges |
| No combustion pollutants indoors | A range may need a 240 V, 40-50 A circuit |
| Less heat into the kitchen in summer | Some models hum or buzz at high power |
How to switch without a big remodel
- Test your pans with a fridge magnet. If it sticks firmly, they’ll work.
- Try a portable single-burner induction plate on a regular outlet before committing.
- Check your panel. Ask an electrician whether a 240 V circuit is available; some 120 V induction ranges with built-in batteries avoid a panel upgrade.
- Look for rebates. Some states and utilities rebate induction ranges; see rebates still available.
FAQ
Can I use cast iron? Yes, it works very well; lift rather than slide it to avoid scratching the glass.
Is induction safe with pacemakers? Ask your doctor or the device maker; some recommend keeping a distance from active induction zones.
