The power consumption of a washing machine can vary depending on the model, capacity, and the specific settings used during the cycle. On average, a standard top-loading washing machine consumes around 0.3 to 2.5 kilowatt-hours (kWh) of electricity per hour of usage.
Front-loading washing machines tend to be more energy-efficient and usually consume around 0.15 to 1.5 kWh per hour. High-efficiency models and those with energy-saving features will typically fall within the lower end of these ranges.
To determine the exact power consumption of your washing machine during one hour of usage, you can check the manufacturer's label on the appliance, the user manual, or the specifications provided by the manufacturer. The label or manual should mention the power rating of the washing machine in watts (W) or kilowatts (kW). Then, you can calculate the consumption using the formula:
Power Consumption (kWh) = Power Rating (kW) × Hours of Usage
For example, if your washing machine has a power rating of 1.2 kW and you use it for 1 hour:
Power Consumption = 1.2 kW × 1 hour = 1.2 kWh
Keep in mind that energy consumption can vary based on the wash cycle's duration, temperature setting, and the size of the load. To minimize energy usage, consider using energy-saving modes, washing full loads, and washing with cold water whenever possible.
