For example, if your microwave is rated at 1,000 watts and you use it for 10 minutes, the calculation will be:
Energy (kWh) = (1,000 watts × 0.167 hours) / 1,000 = 0.167 kWh
Calculating Electricity Costs
Electricity costs vary by location, but in the U.S., the average cost ranges between $0.10 to $0.15 per kWh. To find out how much it costs to run your microwave, use the following formula:
Cost = Energy (kWh) × Cost per kWh
Continuing with the example above, if your electricity cost is $0.12 per kWh, the cost to run your microwave for 10 minutes will be:
Cost = 0.167 kWh × $0.12 = $0.02004
Therefore, it would cost approximately 2 cents to microwave for 10 minutes at 1,000 watts.
Maximizing Energy Efficiency
While microwaves inherently use less energy than traditional ovens, there are several strategies to maximize their efficiency and minimize electricity bills.
Utilize the Right Settings
Optimize your cooking by utilizing appropriate settings. If you’re reheating leftovers, consider using lower power settings to avoid overheating and wasting energy.
