Electric Can Opener Energy Calculator (Cost and kWh Usage)

Electric can openers are one of the most common kitchen appliances in any household. They offer a convenient and easy way to open cans of food without the need for manual effort. However, it’s important to note that they consume energy and therefore, impact the environment and our wallets. In this article, we will explore the energy consumption and cost of using an electric can opener, as well as some money-saving tips.


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

Electric can openers use 170 watts of power, which means that they consume 0.17 kWh (kilowatt-hours) per hour of usage. The amount of energy consumption is dependent on the frequency and duration of usage. For instance, if you use your electric can opener for 10 minutes every day, the energy consumption would be 0.03 kWh per day, 0.9 kWh per month, and 10.95 kWh per year. It’s important to note that this is just an estimate, and actual usage can vary depending on the specific model and usage patterns.

Importance and Relevance

Electric can openers provide convenience and help save time and effort in the kitchen, which is especially important for individuals with disabilities or arthritis. However, they also have an impact on the environment through energy consumption. It’s crucial to be mindful of the usage of all appliances, including electric can openers, to minimize environmental impact and reduce energy costs.

Cost in Dollars of Energy Usage

The cost of energy usage for an electric can opener can be calculated using the following formula:

Cost = Power x Time x Price of energy

Assuming an energy price of $0.12 per kWh, we can calculate the daily, monthly, and yearly costs of using an electric can opener for 10 minutes every day:

  • Daily cost = 0.17 kWh x 0.17 hours x $0.12/kWh = $0.00306
  • Monthly cost = 0.17 kWh x 5.1 hours x $0.12/kWh = $0.09828
  • Yearly cost = 0.17 kWh x 61.8 hours x $0.12/kWh = $1.1796

It’s important to note that actual energy prices may vary depending on your location and energy provider.

Money Saving Tips

Here are some tips to help you save money on the usage of your electric can opener:

  • Unplug the electric can opener when not in use to avoid standby power consumption.
  • Use a power strip to switch off multiple appliances at once when not in use.
  • Consider upgrading to an energy-efficient model that has a lower wattage rating.
  • Purchase a solar-powered can opener to reduce your carbon footprint.

In conclusion, electric can openers offer convenience in the kitchen, but it’s important to be mindful of their energy consumption and cost. By paying attention to usage patterns and implementing money-saving tips, you can reduce energy costs and minimize environmental impact.
