Corded electric lawn mowers are typically more powerful than cordless models and offer longer continuous operation times. Their energy consumption is directly tied to the motor’s power rating, typically measured in watts (W). A higher wattage indicates a more powerful motor, which consumes more electricity.
Typical Power Ratings
Most corded electric lawn mowers have power ratings ranging from 1200W to 1600W. This means they consume 1.2 to 1.6 kilowatt-hours (kWh) of electricity per hour of operation. To put this into perspective, a 100-watt light bulb uses 1 kWh of electricity over 10 hours of operation.
Calculating Electricity Costs
To calculate the cost of operating a corded electric lawn mower, you need to consider your local electricity rates. Assuming an average electricity rate of $0.15 per kWh, a 1500W corded lawn mower operating for one hour would consume 1.5 kWh of electricity, costing approximately $0.23.
Battery Capacity and Energy Consumption in Cordless Electric Lawn Mowers
Cordless electric lawn mowers offer convenience and portability, but their energy consumption depends on the battery capacity and charging frequency. Battery capacity is typically measured in amp-hours (Ah), indicating the amount of electrical charge the battery can store.
Battery Capacity and Run Time
A higher amp-hour rating generally translates to a longer run time. For example, a 5Ah battery might provide 30 minutes of mowing time, while a 10Ah battery could offer an hour of operation. The actual run time can vary based on the mower’s power demands and your lawn’s characteristics.
Energy Consumption During Charging
Charging a cordless lawn mower’s battery consumes electricity, contributing to the overall energy usage. The amount of energy consumed during charging depends on the battery’s capacity and the charging efficiency of the power adapter. Higher capacity batteries naturally require more energy to charge.
Tips for Minimizing Electric Lawn Mower Energy Consumption
While electric lawn mowers generally consume less energy than gas-powered counterparts, you can further optimize their energy usage with these tips:
Charge Batteries Efficiently
Always charge your battery using the recommended charger and follow the manufacturer’s instructions. Overcharging or using incompatible chargers can damage the battery and reduce its efficiency.

Heat can reduce battery lifespan and performance. Avoid storing batteries in extreme temperatures or direct sunlight.
Maintain Your Mower
Regularly clean and sharpen the mower blades to ensure optimal cutting performance. Dull blades require more power to cut grass, increasing energy consumption.
Conclusion: Making Informed Choices
Electric lawn mowers offer a sustainable and convenient alternative to gas-powered models, with minimal environmental impact. Understanding the factors influencing their energy consumption can help you choose the right model for your needs and optimize your energy usage. By considering lawn size, battery capacity, and your mowing habits, you can find an electric lawn mower that delivers efficient performance without compromising on convenience or environmental friendliness.
