The electricity consumption of a dishwasher can vary depending on its energy efficiency, usage patterns, and the specific model. On average, a dishwasher in the United States uses around 1.5 to 2 kilowatt-hours (kWh) of electricity per load. However, the number of loads you run per month will significantly impact the overall monthly electricity usage.
To estimate the monthly electricity consumption, you can follow these steps:
Determine the average electricity consumption per load: Let's assume your dishwasher uses 1.75 kWh per load (a typical value within the range mentioned earlier).
Estimate the number of loads per week: Consider how often you run the dishwasher each week. For example, if you run it three times a week, that would be 3 loads.
Calculate the weekly electricity consumption: Multiply the average electricity consumption per load by the number of loads per week. For example, 1.75 kWh/load x 3 loads/week = 5.25 kWh/week.
Calculate the monthly electricity consumption: Finally, multiply the weekly electricity consumption by the number of weeks in a month. On average, there are approximately 4.33 weeks in a month. So, 5.25 kWh/week x 4.33 weeks/month ≈ 22.7 kWh/month.
Keep in mind that these are rough estimates, and the actual electricity usage may vary depending on the factors mentioned earlier. Some modern dishwashers come with energy-saving features, such as eco-friendly modes or half-load options, which can reduce electricity consumption.
To get a more accurate estimate for your specific dishwasher, you can refer to the manufacturer's documentation or check the appliance's energy label, which typically provides information about its energy efficiency and estimated annual energy consumption.
