The data above provides a broad summary of average television consumption by kind.

Different considerations, however, should be considered.

According to Online Research:

Modern TVs use, on average, 58.6 watts when in On mode and 1.3 watts in standby mode. The power consumption of modern TVs ranges from 10W to 117W (0.5W to 3W on standby). On average, TVs consume 106.9 kWh of electricity per year, costing $16.04 annually to run in the US.

How Many Watts Does a TV Use a Day?

TV watts are the unit of measurement for a TV’s strength or power, similar to how height and weight are measured in feet and inches and kilograms or pounds.

This number is proportional to the size of your television. The age, height, screen type, and the number of hours per day you watch television all affect how much Energy your television uses.

We cannot tell you with accuracy that how many watts of electricity does your TV use in a day.

Still, we can give you an unreliable estimate of how many watts of power your television can use.

For accuracy, You will need information about the manufacturer, model, size, and hourly usage. In this way, You may calculate and project your television’s daily electricity consumption.

If you know the actual watt of power of your television, then this may be calculated using the following formula:

Power consumption (kWh) = Wattage of the appliance (kW) x operating hours (Hrs).

  • For your TV,
  • Power = 100 watt,
  • Operational hours = 12 hours, so let’s feed in the value,
  • Power consumed by your TV in a day (kWh) = 100 watts x 12 hours
  • = 1200 watt-hours.
