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 TV (19 Inch colour) is an important factor to consider when purchasing any electrical appliance. This is because appliances that consume high amounts of energy contribute to increased carbon emissions, which have harmful effects on the environment.

According to the defaults provided, the TV (19 Inch colour) uses 40 watts of power. This may not seem like a substantial amount, but over time, it can add up. It is essential to understand that the energy consumption of a TV varies depending on its size, model and usage. Generally, newer models tend to be more energy-efficient than older ones.

When considering the energy consumption of a TV, it is important to keep in mind that the amount of energy it uses also depends on its usage. For example, leaving the TV on while not watching it, using a high-brightness setting, or using it for extended periods can significantly increase energy consumption.

Importance and Relevance

The importance of energy efficiency in electronic appliances has become increasingly significant in recent years. This is because energy consumption is directly linked to carbon emissions, and reducing our carbon footprint is an essential step towards creating a cleaner and more sustainable future for ourselves and future generations. In addition, individuals can save a considerable amount of money on energy bills by reducing their energy consumption.

Cost in Dollars of Energy Usage

The cost of energy usage for a TV (19 Inch colour) can be calculated using the formula:

Total cost = (power consumption in watts / 1000) x hours used x cost per kWh

Using the defaults provided, we can calculate that the daily cost of using the TV is:

(40 / 1000) x 8 x 0.12 = $0.04

The monthly cost of using the TV is:

(40 / 1000) x 8 x 0.12 x 30 = $1.15

The yearly cost of using the TV is:

(40 / 1000) x 8 x 0.12 x 365 = $14.02

It is important to note that these costs may vary depending on the energy price in different regions or countries.

Money Saving Tips

There are several ways to save money on energy bills when using a TV (19 Inch colour). Some of these include:

  • Turning off the TV when it is not in use.
  • Using power-saving modes, which typically reduce the brightness of the screen and reduce energy consumption.
  • Adjusting the brightness and contrast settings to reduce energy consumption.
  • Opting for an energy-efficient TV when purchasing a new one.
  • Using a power bar or surge protector to prevent energy consumption during standby mode.
  • Unplugging the TV when not in use for an extended period.

By implementing these simple measures, individuals can significantly reduce their energy consumption and save money on their energy bills.


In conclusion, the energy consumption and costs associated with using a TV (19 Inch colour) can have a significant impact on both the environment and our wallets. By understanding the energy consumption of electronic appliances and implementing money-saving tips, individuals can reduce their carbon footprint and save money on their energy bills.
