How to lower the cost of running an electric oven
Electric ovens use their full wattage during preheating, then switch the elements on and off to hold the set temperature. On average, a 3,000W oven baking at 350°F uses roughly 60% of its rated power — about 1.8 kWh per hour. Convection mode can shorten cooking times by about 25%, and a smaller appliance like an air fryer or toaster oven uses far less energy for small meals.
- Skip preheating for long roasts and casseroles where precise timing doesn't matter.
- Use convection mode and lower the temperature by 25°F.
- Cook several dishes at once, and use the air fryer or microwave for small portions.
