Nowadays the TVs are rather efficient, so the electricity usage of a TV it is quite low if we take into account the amount of time they are powered on.

On this page you will find out:

Electricity measurement units: Watt, Kilowatt or Kilowatt hour

Alternatively, you may want to fast forward to the TV electricity cost calculator.

How much electricity does a TV use

All the TVs should have a label describing at the very least their power consumption. Some TVs will also be labelled with information about the stand-by power consumption.

Television electricity usage

If you are considering to purchase a new TV, better have a look to the specifications. The power consumption of a TV can significantly increase our electricity bills so better to know the electricity cost in advance.

For example, according to the specifications of our TV, it is estimated that it uses 532 Kilowatts hour (kWh) per year. Because we are paying to our electricity provider 0,217 euro per every kWh we consume, that means that our TV is going to cost us around 115 euro on electricity every year.

532 kWh x 0,217 euro per kWh = 115,44 euro per year

Electricity cost calculator

The calculator below can be used to calculate the energy consumption and cost of a TV over a year. 

You just need to adjust the values in the PARAMETERS section to your requirements and the calculator will automatically display the RESULTS section.


For example, if your laptop’s adapter:

> It has a power consumption of 532 kWh per year

> You are paying 0,2 euro (or dollars or pounds) per every kWh you consume 

You will be paying around 106 euro (or dollars, or pounds, or…) per year in electricity costs.

If you are planning to buy a new TV and want to know its electricity consumption, use your favorite browser to have a look on the internet for it’s specifications. 

In the majority of the cases, the specifications will describe the yearly power consumption of the TV.

Still, if you want to know the exact electricity usage of your laptop, your best option is to use a plug in power meter to measure the electricity consumption. 

Clicking on the image below it will redirect you to the Amazon page where you can have a look to the specifications of the power meter we use for our measurements.

All of our house appliances and devices like the washing machine, the dishwasher, the TV or the printer are plugged to a wall socket. 

So, with a power consumption meter we can determine how much electricity our appliances or devices are using and, more importantly, we can measure the electricity usage over a period of time.

Electricity measurement units

Not everybody it is familiar with terms like Watts, Kilowatts or Kilowatt hours so if you would learn more about them, have a look to this YouTube video that we have prepared about this topic.

What is a Kilowatt hour (kWh)

Or you can have a look to this electricity measurement units calculators to get a better understanding of:

How to lower the electricity bill

If you are concerned that your TV may be using too much electricity, here are some tips that you can apply to reduce the electricity usage:

1.- Enable the power saving settings

Most probably your TV it is setup to stay in standby mode waiting for your commands. 

While in standby, your TV will use electricity, even if it is not in use. This is, your TV will be using electricity while your are sleeping, away from home or just cooking or having a shower.

If you would like to learn more about standby electricity usage, have a look to this video:

Standby Power Consumption

2.- The larger the TV is, the more electricity it will use

It may not always be the case but the larger the TV is the more electricity it will use. Be aware of this when you decide to buy a new TV and have a look to the specifications, find the power usage and compare it to other TV models.

Energy conservation

Energy conservation can be defined as the decision and the act of using less energy

Energy conservation both benefit you and the environment

The act of saving and conserving electricity does benefit you because you will be paying less on your energy bills. 

And it also does benefit the environment because conserving electricity prevents any unnecessary waste of natural resources.

Now, at individual level it may not look worth to try to save a few watts here or there. 

Still, every little counts and if hundreds or thousands of us do save a little every time, it will make an important contribution towards conserving our natural resources.


For example, if 9000 households would manage to save as little as 10 Watts per day (0,01 kWh) that would add to 32850 Kilowatt hour (kWh) saved per year. 

9000 households x 0,01 kWh per day x 365 days per year 

32,850 kWh saved per year

That is a considerable amount of electricity, but let’s add additional perspectives for clarity:

> Assuming an average cost of 0,18 euro (or dollars, or pounds, or any other currency) per kWh, we would collectively be saving nearly 6000 euro per year.

> To produce 32,850 kWh of electricity it is necessary to use around 17 metric tons of coal or 56 barrels of residual fuel oil.

Have a look to this page for more information about the amount of resources needed to produce electricity.

In any case it is clear that small energy savings do really count when looking into the bigger picture.
