does a tv use a lot of electricity

Does a TV use a lot of electricity? Well, if you’re also asking this question, stick around to learn everything you need to know.

Generally, a TV device doesn’t use much electricity. It really depends on the size of the screen, operating system, and what else turns on along with your TV.

A good proportion of the TVs use around 80 to 400 watts. It really depends on the size of the TV and the time you use it. Given the average power prices, a 42 inch TV that works around five hours a day will cost you ~$2. Your monthly price is going to be around $9 and the year consumption will translate to about $100.

There are, however, quite a few things you need to take under consideration so you can calculate exactly how much electricity your TV consumes.

Does TV Use A Lot Of Electricity?

Based on average statistics, one TV isn’t going to consume a portion of power you should be worried about.

The regular TV, on its own, does not use a lot of electricity. However, depending on the brightness, volume, screen size, and uptime you could reach higher consumption thus higher price.

Let’s now see the general factors that can fluctuate the power consumption of your TV:

How To Calculate TV’s Electricity Usage?

The average electricity usage of your TV is based on several factors. Down below we have provided the essentials determining your TV’s daily power usage:


One of the most important things, when it comes down to TV power usage calculation, is uptime.

In other words, the uptime is how many hours your TV has been working during the day.

TV Size

The next thing you should take into consideration when calculating your TV’s usage is the TV’s size.

When comparing a 32-inch TV with a 55 inch TV, it is obvious that the larger TV is going to consume more electricity than the smaller one.

Additional Devices

The more devices you have attached to your TV (TV boxes, antennas, consoles, and so on…), the more electricity your setup is going to consume.

Operating System

For example, Android TVs will consume more electricity in comparison to non-smart TVs.

That’s because to run heavier software the TV requires more processing power; thus more power is being used.

Brightness & Volume

A TV playing audio higher, with increased brightness will definitely consume more power than a TV with a dimmer display and lower levels of audio.

Given those factors, you will be able to come up with an audible estimation of power consumption. Let’s now compare the daily, monthly, and yearly usage of your TV.

How To Come Up With TV’s Average Electricity Bill?

Most people want to find out how much electricity does their TV consumes in order to calculate the bill at the end of the month. This is exactly what we are going to do.

Let’s see what are the parameters of your average TV’s electricity usage in a day, month, and in a year.

TV Power Consumption Per Day?

Given the average statements by the TV researchers, a television that has been working for around 5-6 hours a day, generates around $2 of electricity bills.

You can stretch that statement, based on the daily hours you use your TV for and come up with the average electricity bill you’re going to have to pay.

Let’s say your TV works 12 hours a day. This will cost you up to $4.50 dollars if your TV is over 32 inches.

Simply measure the hours you’re watching your TV for and consider that 6 hours of watch time generates a $2 electricity bill. Increase the 5–6-hour price accordingly with the screen size.

TV Power Consumption Per Month?

The monthly power consumption of your TV for the average user is being around $9, given the 5-6 watch hours per day.

Even if your TV works 24/7 during the month, you will barely get over $25 only for the TV.

TV Power Consumption Per Year?

For the users who are seeking to learn their TV’s yearly usage, it could vary from $22 up to $100 electricity bill per year, generated from your TV.

Depending on the daily usage you’ve come up with, multiply that by 30 (average) and then by 12 months.

This statistic really depends on how you are using your TV during that time. That calculator should give you the approximate yearly bill that only your TV generates.

Does Plasma TV Use A Lot Of Electricity?

The average power supply of your plasma TV might be from 200 to 500 watts for a 42-inch model.

If you’re a fan of larger TV and let’s say the TV is 60-plus-inch, the power supply can jump up to 500 to 600 watts.

Calculating the electricity bill you’re going to give in a month for that type of usage is about $18 to $20 dollars for around 4-5 hours of watch time per day.

If you were to watch more than 10 hours per day, your plasma TV’s electricity bill can jump over $40.

Since most of the TVs are plasma nowadays, you won’t be worrying much about the power usage, caused by the optimization.

How To Reduce TV’s Power Usage?

If you’re interested in reducing your TV’s power usage, you can try a few things recommended widely.

Here are a few things you can do to minimize the power your TV is consuming:

Use Energy-Saver Mode

There is a mode implemented on your TV meant for reducing power usage.

In most cases, it is called “energy-saver mode” or “eco-mode” in your TV’s interface. When enabled your TV will start using less power.

Turn off Your TV Regularly

Leaving your TV running whenever you aren’t at home is the biggest power consumer.

Make sure to shut the device off when not watching it to save additional power. You can also use a sleep timer.

Configure Ambient Light Sensor

Your TV is most likely to have an ambient light sensor feature that will let you adjust settings, that consume power.

Switch TV to Standby Mode

You can switch your TV to standby mode from the settings, which will prevent unnecessary uptime.

Applying any of the recommendations above are guaranteed in reducing your TV’s overall power consumption.

Even if little, you will definitely see changes in regard to your TV’s electricity bill during the next month.

Bottom Line:

Your TV’s power usage is based on its size, power supply, and overall uptime. The average TV’s power supply is from 200-400 watts and consumes up to $2 in electricity per day.
