Choosing a stove involves more than cooking preference — energy costs, ventilation requirements, and cookware compatibility all matter. Here's a full comparison of induction, gas, and electric stoves on efficiency, cost, and performance.
Induction: Most Efficient, Highest Upfront Cost
Induction cooktops transfer energy directly to compatible cookware through magnetic fields, with 85–90% efficiency (only 10–15% of energy is lost as ambient heat). This compares to 74% for electric resistance and 40% for gas. A mid-range induction range costs $900–2,000. Induction heats faster than gas or electric, offers precise temperature control, and doesn't heat the kitchen. Requires magnetic cookware (cast iron, stainless steel — check with a magnet). Incompatible with copper, aluminum, and most non-stick pans unless specifically labeled induction-compatible.
Gas: Precise Control, Lowest Efficiency
Gas ranges cost $500–2,000 and achieve only 32–40% efficiency — the majority of heat goes into the kitchen and ventilation. Annual cooking cost for a family of 4: $30–60/year in gas at $1.30/therm. Gas allows visual flame control and works with any cookware, but requires a gas line and proper ventilation. Indoor air quality research has raised concerns about NO₂ and other combustion byproducts from gas stoves, particularly in poorly ventilated kitchens.
Electric Resistance (Coil/Smooth Top): Middle Ground
Standard electric ranges cost $400–1,200 and achieve 74% efficiency. Annual cooking cost: $50–80/year at 13¢/kWh. Smooth-top glass-ceramic electric ranges are easy to clean but slow to heat and cool. Coil electric ranges are the cheapest but least convenient. Electric ranges work with any flat-bottomed cookware.
Annual Cooking Cost Comparison
- Induction (at 13¢/kWh): ~$40–60/year
- Electric resistance (at 13¢/kWh): ~$50–80/year
- Gas (at $1.30/therm): ~$30–60/year
Cooking represents a small fraction of home energy costs — the choice of stove type has minimal impact on total energy bills. The bigger considerations are efficiency, cooking experience, and air quality.
