Who doesn’t own a TV these days? Almost everyone has one. We also need to pay electricity bills. We’ll thus see how much electricity does a TV use. People often wonder how much electricity does a TV use. Everyone should know this so that they can control the amount of electricity they spend daily on TV. We will hence discuss this question in this blog and support our answer with some facts and data.

Types of TV Sets –>

Because it is a technology that is constantly evolving, there are many different types of television sets. In the past, most people had cathode ray tube sets (CRTs) in their homes, but today there are a number of sleeker sets that are capable of displaying premium quality images. So, let’s see the different types of TV sets, one by one:


LCD screens slowly made their way into homes in the late 1990s and early 2000s. The main difference between these sets and others was the fact that they were slimmer, allowing homeowners to mount them on the wall. LCD Televisions work by using pixels, tiny lights in red, blue and green colors that are quickly manipulated to create moving color images. In a LCD television, the pixels are electronically controlled by liquid crystals, hence the name liquid crystal display. LCDs also use less energy than older CRTs.

Plasma TV

Plasma is essentially a gas that can conduct electricity. The more energy added to this gas, the more activity occurs at the molecular level, causing particles to collide and release photons of light. The process of displaying images makes it possible to combine plasma televisions into apartment-panel displays, just like LCDs. At the beginning of the twenty-first century, LCDs gained prominence, and so did plasma televisions. While they are considered to have higher contrast than LCDs, they are not as energy efficient in comparison.

Just as there are LED light bulbs, there are LED televisions that consumers can buy. Although they use a LCD screen, the light source in the actual televisions of these electronics is a LED. These bulbs are among the most energy efficient and compact available on the market. This fact allows LED televisions to be even thinner than others. When comparing LED TVs to LCD TVs, the only difference between the two is the backlight. So the only difference is energy consumption, and there is no difference in picture quality.

The Intelligent One — A Smart TV

One of the latest developments in the field of television is the development of smart TV. This TV is essentially the same as its counterparts, but differs from them in terms of its need to connect to the Internet. By connecting to your home network, the smart TV can access applications such as Netflix and Amazon Prime to stream content.

Comparing the overall energy consumption of each TV, the LED is the most efficient of the three. It uses two-thirds the amount of electricity that a LCD TV uses and one-third that a plasma TV uses.

You might do good to also remember that LCD TVs and Plasma were advertised as the better option in comparison to traditional Cathode Ray Tubes (CRT) technology of cumbersome TVs. This is because they consume less power and space but are on the expensive side. However, it is now the generation of LED TVs with CRT obsolete.

How much electricity does a Smart TV use?

In case your TV is not completely unplugged then it will consume about .05 watts of power. Remember that this will happen even if the TV is “off” or in the “standby” mode. A smart TV will thus consume an average of 157 watts of power. When you leave your TV on for 24 hours then an average TV will use up to 6.36 kilowatt-hours. So, if you want to save power then you should completely unplug your TV.

How much does it cost to have a TV running for 24 hours?

On the basis of wattage or amount of power your Smart TV consumes in an hour, you will thus get to know the power consumption. We will now consider the Samsung Q80T QLED 65-inch smart TV as an example. This model uses up to 265 watts of power in an hour thus. When you leave this smart TV on for 24 hours then it will consume up to 6,360 watts or 6.36 kilowatt-hours. In this case, if you pay $.12 cents per Kilowatt hour then running this model for 24 hours will cost you around $.76 cents.

TV Sets use Vampire Energy — Now, what’s that?

TV Sets being susceptible to Vampire Energy refers to the drain of energy from devices that are turned off but still plugged in. This phenomenon can be countered by using power strips that can accommodate televisions, cable boxes and other electronic accessories such as video game consoles. Simply unplugging the power strip will cut the power to all of these devices, preventing vampire energy from costing you money.

Is it possible to reduce the amount of electricity a Smart TV uses?

There are also various things that you can try for lowering the amount of electricity that your smart TV uses. For instance, lowering sounds, changing backlight settings, and using the built-in time of the smart TV.

Does your TV uses electricity when left on?

It is for sure that when you leave your TV on for a long period of time, your electricity bill will increase. There are many users who keep their TV on for the whole night or when they are away from home. This may be because of the ambient noise or to simulate someone being home. But this can use up a lot of electricity and it also has the disadvantage of overheating your TV. This will cause damage to your TV over time.

Do Smart TVs use electricity when switched off?

Your TV enters a Standby mode when you switch off your smart TV by using a remote or the power button. You can call this “Off” because the TV is still plugged in and using electricity. The amount of electricity consumption may be small in the standby mode but it’s still there. The TV remains on standby for your smart home or remote control to turn it on quickly hence.

As already mentioned above, the standby mode thus will consume only 0.5 watts of power in an hour. However, it will accumulate if you leave it off for a long period of time. This is the reason we recommend you unplug all appliances, rather than just switching them off with your remote. This will surely keep your power consumption at bay.

Do bigger TVs consume more electricity?

The power efficiency of smart TV does not necessarily depend on the size of your TV but on the quality of components. For instance, a small Smart TV using various apps running at the same time will use more power than a larger TV that is not smart. Many manufacturers have their own sets of components that are more efficient in power consumption than other brands. However, you have to keep in mind how much of your Smart TV you are using at once.
