Clothes Dryer Energy Calculator (Cost and kWh Usage)


Clothes dryers are a common household appliance used in most parts of the world. They are convenient for drying clothes, especially when the weather outside is unfavorable. However, the constant use of a clothes dryer can lead to high energy consumption and increased costs. In this article, we will discuss the energy consumption and cost implications of using a clothes dryer, and provide some money-saving tips to help reduce energy costs.


How To Use This Calculator

Using this energy calculator is a simple and will help you determine the costs of running your appliance. Click on ‘Calculate’ to use the predefined values, or enter your daily usage in hours, appliance watts, and your current energy costs in dollars. The calculator will provide you with the daily, monthly, and yearly results. It’s important to ensure the accuracy of the information entered to get the most accurate results.

Hours Used Per Day

Enter the number of hours you estimate the appliance will be on throughout the day. To use fractions of an hour please use a decimal point in the form.

For example: 1 hour and 30 mintes would be 1.5, and 3 hours and 15 minutes would be 3.25

Power Used in Watts

The calculator already includes a default average wattage. If your appliance uses a different wattage then enter it in the calculator.

Your Energy Rate in kWh

The calculator includes an average energy rate (price in $/kWh) to use for the calculation. This may not be the exact price that you’re currently paying for electricity. If you know your energy rate please enter your price per kilowatt-hour.

Energy Consumption

The energy consumption of a clothes dryer depends on its power rating and how long it is used. The default power rating of a clothes dryer is 1000 watts, and the current energy price is $0.12/kWh. To calculate the energy consumption, we use the formula:

Energy Consumption (kWh) = Power rating (W) x Time (hours) / 1000

For example, if you run a 1000-watt dryer for 2 hours, the energy consumption would be:

Energy Consumption (kWh) = 1000 W x 2 hours / 1000 = 2 kWh

This means that every time you run a dryer for 2 hours, you consume 2 kWh of energy.

Importance and Relevance

The use of clothes dryers is important and relevant today because it affects the environment and our wallets. The energy used by clothes dryers comes from power plants that burn fossil fuels, which contributes to air pollution and climate change. By reducing the energy consumption of clothes dryers, we can reduce carbon emissions and protect the environment. Additionally, clothes dryers consume a lot of energy, and therefore, increase electricity bills, which can put a strain on people’s finances.

Cost in Dollars of Energy Usage

The cost of using a clothes dryer depends on the energy consumption and the cost of electricity. In the United States, the average cost of electricity is $0.12/kWh. To calculate the cost of using a clothes dryer, we use the following formula:

Cost = Energy consumption (kWh) x Energy price ($/kWh)

For example, if you run a 1000-watt dryer for 2 hours, the energy consumption would be 2 kWh, and the cost would be:

Cost = 2 kWh x $0.12/kWh = $0.24

This means that every time you run a 1000-watt dryer for 2 hours, it costs you $0.24.

To calculate the daily, monthly and yearly costs, we use the following examples:

  • Daily cost: If you use a 1000-watt dryer for 2 hours every day, the daily cost would be: 2 kWh x $0.12/kWh = $0.24/day
  • Monthly cost: If you use a 1000-watt dryer for 2 hours every day for a month, the monthly cost would be: 2 kWh x $0.12/kWh x 30 days = $7.2/month
  • Yearly cost: If you use a 1000-watt dryer for 2 hours every day for a year, the yearly cost would be: 2 kWh x $0.12/kWh x 365 days = $87.6/year

Money Saving Tips

Here are some money-saving tips to help reduce the energy consumption and costs of using a clothes dryer:

  • Clean the lint filter before every use. A clogged filter reduces the dryer’s efficiency, which means it will take longer to dry clothes and consume more energy.
  • Use the moisture sensor option. Most modern dryers have a moisture sensor that automatically turns the dryer off when the clothes are dry. This saves energy and reduces the risk of over-drying clothes.
  • Dry clothes in batches. Drying clothes in batches reduces energy consumption because the dryer retains heat from the previous load.
  • Hang clothes outside to dry. On sunny days, hanging clothes outside to dry is a great way to reduce energy consumption and costs.
  • Use a lower heat setting. High heat settings consume more energy. Use a lower heat setting when possible.
  • Time your drying cycle. Set a timer for your drying cycle to avoid over-drying clothes, which wastes energy and can damage clothing.

In conclusion, clothes dryers are convenient appliances that make our lives easier. However, their energy consumption can add up quickly and lead to high energy costs. By implementing some money-saving tips, we can reduce our environmental impact and save money on our electricity bills.
