# AV Receiver Energy Calculator (Cost and kWh Usage)

When it comes to home entertainment systems, an AV receiver is an integral part of the setup. It serves as the central hub to which all of the audio and video components are connected. These devices can be a bit of an energy hog, so it’s important to consider the energy consumption and associated costs. This article will provide an in-depth look at the energy consumption and costs of using an AV receiver, as well as some money-saving tips to help keep your energy bills in check.

## 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 an AV receiver can vary depending on the model and how it’s being used. On average, an AV receiver uses around 450 watts of electricity when in use. This can add up quickly if you’re using your home entertainment system frequently. To put this into perspective, a 450 watt AV receiver left on for 4 hours a day, 7 days a week would use about 50 kWh of electricity per month. This is equivalent to leaving a 100 watt light bulb on for 500 hours.

It’s important to note that the energy consumption of an AV receiver also varies depending on the volume level and the number of speakers being used. Higher volumes and more speakers will require more power, so it’s important to use your AV receiver efficiently.

## Why Is This Important?

The energy consumption and associated costs of using an AV receiver are important because they directly impact both the environment and your wallet. The more energy that is consumed, the higher the associated greenhouse gas emissions, which contribute to climate change. Additionally, using more energy will result in higher electricity bills, which can be a significant expense over time.

## Cost in Dollars of Energy Usage

To calculate the cost of using an AV receiver, you need to know the wattage of the device and the current energy price. Using the defaults provided above, we can calculate the hourly cost of using an AV receiver:

Hourly cost = wattage / 1000 x energy priceHourly cost = 450 / 1000 x \$0.12Hourly cost = \$0.054

Using the hourly cost, we can calculate the daily, monthly, and yearly costs of using an AV receiver:

Daily cost = hourly cost x hours used per day

Daily cost = \$0.054 x 4 = \$0.216

Monthly cost = daily cost x days used per month

Monthly cost = \$0.216 x 30 = \$6.48

Yearly cost = monthly cost x 12

Yearly cost = \$6.48 x 12 = \$77.76

As you can see, the cost of using an AV receiver can add up quickly over time. However, there are ways to reduce these costs and save money.

## Money Saving Tips

1. Use Energy-Saving Mode: Many AV receivers have an energy-saving mode that can help reduce power consumption when the device is not in use. This can be a great way to save energy and reduce your electricity bill.
2. Use a Power Strip: Using a power strip is a great way to reduce standby power consumption. When your AV receiver is turned off, it still draws power in standby mode. By connecting your AV receiver to a power strip, you can easily turn off all of your devices at once and reduce standby power consumption.
3. Turn Off Unnecessary Devices: When you’re not using your AV receiver, be sure to turn off any unnecessary devices. This includes speakers, gaming consoles, and streaming devices. This can help reduce power consumption and save money on your electricity bill.
4. Upgrade to Energy-Efficient Devices: If you’re in the market for a new AV receiver, consider purchasing an energy-efficient model. These devices are designed to use less energy and can help reduce your electricity bill over time.

By following these money saving tips, you can reduce your energy consumption and save money on your electricity bill. Additionally, you’ll be doing your part to protect the environment by reducing greenhouse gas emissions.
