LED TV Energy Calculator

Televisions are an essential part of our daily lives, and with technological advancements, they’re becoming more energy-efficient. The 49-inch LED TV is an excellent example of an efficient appliance, but it’s still essential to understand its energy consumption and cost of use. In this article, we’ll dive into how much energy this appliance uses, its impact on our lives, the cost of energy usage, and 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

The energy consumption of an appliance is measured in watts. The 49-inch LED TV uses 85 watts of energy when it’s turned on. Energy consumption is an important concept as it directly impacts the environment and the cost of using the appliance. By understanding the energy consumption of this appliance, we can make informed decisions about how to use our energy resources.


The subject of energy consumption is more important today than ever before due to the increasing demand for energy and the impact of its use on the environment. Energy is a finite resource, and we must use it wisely to reduce our carbon footprint. By using energy-efficient appliances like the 49-inch LED TV, we can decrease our energy consumption, lower our energy bills, and reduce our impact on the environment.

Cost in Dollars of Energy Usage

The cost of energy usage can be calculated by multiplying the energy consumed in kilowatts by the cost per kilowatt-hour (kWh). The current energy price is $0.12/kWh, and the 49-inch LED TV uses 85 watts of energy. Here are some examples of daily, monthly, and yearly costs:

  • Daily cost: 85 watts * 24 hours = 2040 watt-hours or 2.04 kWh * $0.12 = $0.24/day
  • Monthly cost: $0.24/day * 30 days = $7.34/month
  • Yearly cost: $0.24/day * 365 days = $89.35/year

Money Saving Tips

Here are some money-saving tips for the 49-inch LED TV:

  • Adjust the brightness: Reducing the brightness even by a small amount can significantly reduce energy consumption.
  • Turn off the TV when not in use: Turning off the TV when not in use can reduce energy consumption by up to 50%.
  • Use power-saving mode: Many TVs come with a power-saving mode that reduces energy consumption when the TV isn’t in use for a specific time.
  • Unplug when not in use: Even when turned off, appliances use energy when they’re plugged in. Unplugging the TV when not in use can save energy and money.
  • Buy Energy Star certified appliances: Energy Star certified appliances are designed to be more energy-efficient and can significantly reduce energy consumption.


Understanding the energy consumption and cost of using the 49-inch LED TV can help us make informed decisions about energy use. By using energy-efficient appliances and adopting energy-saving habits, we can reduce our energy consumption, lower our energy bills, and reduce our impact on the environment.
