How Much Electricity Does A TV Use

How much electricity does a tv use? Today, it’s not uncommon to have a TV in almost every household. Several TV sets are kept up and running at the same time.

As a result, technology keeps improving with more energy-efficient appliances, even within just one household! But how do you determine exactly how much energy your TVs are consuming?

This article will show you some different ways of measurement so that you’ll know exactly which devices are eating up more energy and ultimately affecting your electricity bill.

Then help you decide whether they’re worth keeping around anyhow or if they should be replaced with something better (which may or may not use less Electricity)

How Much Electricity Does A TV Use?

guide on how much electricity does a tv use

On average, most individuals in the U.S. use a total of about 900 watts of Electricity daily.

However for many homes, this will be less such as one who is living more countryside than the city, or who is living in an apartment with multiple people and therefore using less basic appliances throughout the day.

On the other spectrum, we have not taken into account that because electricity prices differ considerably by state.

This number could potentially land at between 350 watts and 2000 watts per TV used within each bracketed area and it’s best to consult your local utility company for exact details and cost-saving tips.

So you may determine for yourself what number (and hence wattage) falls more appropriately within your own specific home(s).

How much is a TV amount of Electricity required per Hour?

A label on the back of most TVs states how much energy the television uses, and the wattage number is marked with a “W” at the end.

All you must do is multiply the wattage number by how many hours you watch your TV per day, and then you will get an idea of how many watt-hours have been used just to keep it turned on for however long.

By dividing that number by 1,000, you will obtain your daily electricity usage in kilowatt-hours (kWh). Keep in mind that every state has a different price for their kilowatts.

Which thing determine TV’s Energy Consumption?

The people who watch the most TV usually spend much more on their electrical bills because they leave their televisions turned ON in between watching shows.

Although saving money is not the main concern, it’s something you need to think about.

Moreover, it would help if you focused on finding TVs that exhibit an efficient use of energy and a good quality picture so that one can savour every moment of entertainment being provided by the television.

A group of friends might decide to get together and purchase a new tv and share it since this is one mode of saving money by sharing expenses. Age, Size & Screen Type are the main things that determine Energy Consumption.

Average Power Consumption Calculations of several Types of TVs

In the average household, a family watches TV for approximately 5 hours a day, which amounts to 150 hours per month or 1,800 hours per year.

This statistic does not determine the amount of power that the television itself consumes.

Rather, it indicates how much energy is being used as part of the usage by electricity generators to ‘make’ that Electricity from other sources such as coal power plants.

To determine an approximate estimation of your TV’s energy use, you would multiply 1,800 (the number of hours watched each year) by 0.077 kilowatt-hours per Hour to come up with around 136 kilowatt-hours consumed by a typical 60″-screen model. Let’s go over the most common televisions available on the market today.

1. Cathode-ray Tube TV

These are cathode-ray tubes, a relic from the ’80s. While it is difficult to find a TV repairer who can fix these dated models, their benefits include durability and image quality over the years.

What makes these TVs so wasteful is that they consume anywhere between 0.5 kW and 1 kW of power per day on average, which might not seem like much.

But when 12 months pass and you have watched 36 to 48 TV episodes in your free time (please don’t add it up!), that amount reaches around 17 kW per month!

Quite a shocking figure from something we use in our homes as just one more piece of furniture. And this doesn’t even take into account the energy used by your old tube TV when it thinks no one’s watching.

Standby mode uses 2 to 3 watts an hour at this point – which means we aren’t only paying for our TV show habits but also for what we previously considered a “free” service.

2. LCD or LED TVs

The amount of Electricity our LCD TVs consume depends on the size of the screen. The smaller models use anywhere from 40 to 55 watts per Hour when turned on, comparable to other small home appliances.

However, when it is in sleep mode and not turned on, our TVs use only 1 watt of power. For a 32-inch model, our TVs would use somewhere between 6.72 and 8.97 kilowatt-hours of power a month.

According to the kWh infographic, that’s enough energy — to run a coffeemaker or powerful hairdryer for five straight years! LED technology offers significant power savings compared with LCD screens.

While most LED panels use approximately 50 per cent less power than comparable LCDs, some new ‘power-saving’ models can reduce that consumption by as much as 600 per cent!

So if one purchased an ultra-low-power LED TV (for example, with a 49-inch model), this could save between 15.22 – 22.72 kWh each month!

3. Plasma TV

Plasma TVs have a lot of power consumption. The quality of the picture is extremely important for the plasma TV, and thus, it needs to be switched on all of the time. (42 Inch Plasma TV XVT3D424SV).

One 42-inch plasma TV that weighs around 112 lbs. can consume from 150-190 watts per Hour, while in the sleep mode, it only needs 0.5 watts (Onanoff (EXPIRED)).

As a result, such equipment consumes a maximum of 24.36 kW per month if in operation around 8 hours daily.


How much electricity does a tv use? When purchasing a new TV, you want to think about more than just its price and picture quality. You also want to make sure the television is energy efficient, using Electricity wisely.

Today’s high-definition televisions can emit lots of bright light to cause headaches and sleeplessness in some people. Many HDTV models have a special setting called “Night Mode”.

Which reduces glare, making the television easier on your eyes while watching in a dark room.

The amount of Electricity used by TVs varies greatly depending on the model and features – big screens with high resolution devour Electricity whereas older models use far less power.
