DAB Mains Radio is a device that enables us to listen to radio stations. It uses 5 watts of energy when plugged into a power outlet. This means that if you use it for an hour, it would consume 0.005 kWh of energy. However, if you leave it on for longer periods, the energy consumption would increase.

## 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.

## Impact

The subject of energy consumption is extremely important today because it directly affects our environment. The more energy we consume, the more greenhouse gases are emitted into the atmosphere, leading to climate change. Moreover, energy consumption also affects our daily lives in terms of electricity bills. Therefore, it is important to understand how much energy we are consuming and how we can reduce it to make a positive impact on the environment and our wallets.

## Cost in Dollars of Energy Usage

To calculate the cost of using a DAB Mains Radio, we need to know the energy consumption and the energy price. As per the default provided, the energy price is $0.12/kWh, and the energy consumption of the DAB Mains Radio is 0.005 kWh per hour. Therefore, the cost of using the DAB Mains Radio for one hour is:

`Cost = Energy consumption x Energy price`

`Cost = 0.005 kWh x $0.12/kWh`

`Cost = $0.0006`

If we use the radio for 4 hours a day, the cost per day would be:

`Cost per day = Cost per hour x hours per day`

`Cost per day = $0.0006 x 4`

`Cost per day = $0.0024`

The monthly cost would be:

`Cost per month = Cost per day x days in a month`

`Cost per month = $0.0024 x 30`

`Cost per month = $0.072`

Similarly, the yearly cost would be:

`Cost per year = Cost per month x 12`

`Cost per year = $0.072 x 12`

`Cost per year = $0.864`

## Money Saving Tips

- Unplug the DAB Mains Radio when not in use to save energy.
- Use rechargeable batteries instead of the mains power to power the radio.
- Invest in a timer plug to turn off the radio automatically after a certain time.
- Purchase an energy-efficient radio.
- Listen to the radio on your smartphone or laptop to save on energy and cost.

By following these tips, you can save money and reduce your energy consumption, which would be beneficial for the environment. For example, if you use rechargeable batteries, you could save around $8 per year, and if you purchase an energy-efficient radio, you could save up to $15 per year.
