How much electricity does a TV use? Find out here and see the most efficient models based on a study of 107 of the best TVs on the market.
The following is based on a study of 107 of the best and most energy efficient TVs on the market.
- 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.
- 94% of Energy Star certified TVs are LED TVs – 89% of these are direct-lit LED TVs, while 11% are edge-lit.
Screen size and resolution have a considerable impact on how much electricity a TV uses. The average, most common and lowest TV wattage is listed by size and resolution, below.
The most energy efficient TV models by size and resolution are also listed below.
On average, modern TVs use 58.6W when on and 1.3W on standby. Per year, TVs use 106.9kWh of electricity, which costs $16.04 on average in the US.
The most common TV wattage in the study was 117W when on and 0.5W when on standby. Per year, the most common TV consumes 206kWh of electricity, which costs $30.90 to run (at 15 cents per kWh).
Older TVs, e.g. CRT and plasma TVs, were less energy efficient. Modern LCD and LED TVs are considerably more efficient, with LED TVs being most efficient.
94% of Energy Star certified TVs are LED TVs. 89% of these are direct-lit LED TVs, while 11% are edge-lit.
TV wattage varies considerably with screen size and resolution. So let’s take a look at how they impact how many watts a tv consumes.
How many watts does a TV use?
As mentioned, on average, a TV uses 58.6 watts when on, and 1.3 watts on standby, with the most common TV wattage consumption being 117 watts while in On mode and 0.5 watts when in standby mode.
The TV that uses the lowest amount of watts is the Sceptre – E18, at just 10 watts while on and 0.5 watts on standby.
Screen size, resolution and other factors impact the amount of watts a TV uses. The following tables break down the average TV wattage by screen size and resolution.
Briefly, to summarize:
- As expected, the average TV wattage consumption increases with TV size and screen resolution.
- On average, a 55 inch TV uses 77 watts while on and 1.4 watts on standby.
- On average, 4K (2160p) TVs use 80 watts while on and 0.6 watts on standby.
The table below lists the average wattage for popular TV sizes, along with the most common and lowest wattage. The amount of watts used on standby is also included.
|TV size||Result category||Watts used while On||Watts used on Standby|
|19 inch TV||Average||16.5W||0.5W|
|24 inch TV||Average||19.8W||0.8W|
|32 inch TV||Average||28W||0.7W|
|40 inch TV||Average||34.1W||0.5W|
|43 inch TV||Average||47.8W||0.9W|
|50 inch TV||Average||70.5W||2.1W|
|55 inch TV||Average||77W||1.4W|
|65 inch TV||Average||94.7W||1.1W|
|70 inch TV||Average||109.1W||0.5W|
|75 inch TV||Average||114.5W||2.6W|
This table demonstrates that, as expected, TV wattage increases with TV size.
On average, 75 inch TVs use 114.5 watts while on and 2.6 watts on standby. The most common 75 inch TV consumption is 117 watts while on, with standby mode consuming 3 watts.
The lowest wattage recorded for 75 inch TVs is 87.3W (0.5W on standby).
But how does screen resolution impact the amount of watts a TV uses?
The table below shows the average, most common and lowest TV wattage for different screen resolutions (in both On and Standby modes).
|TV resolution||Result category||Watts used while On||Watts used on Standby|
As you can see, the amount of watts a TV uses increases with screen resolution.
On average, full HD (1080p) TVs use 33.3 watts while on and 0.5 watts on standby.
The most common full HD TV consumption is 31.1 watts while on, with standby mode consuming 0.5 watts.
The lowest full HD TV wattage is 14.5W (0.5W on standby).
Now that we know how many watts a TV uses, let’s take a look at how much electricity a TV uses over time.
How much electricity does a TV use?
The amount of electricity a TV uses over time is measured in kilowatt-hours (kWh).
On average, a TV uses 106.9 kWh of electricity per year. The most common annual TV consumption is 206 kWh.
The TV that uses the lowest amount of electricity per year, at 19.6 kWh, is the Sceptre – E18.
When reporting on the amount of electricity a TV uses annually, Energy Star and manufacturers typically assume 5 hours in On mode (daily), and 19 hours (daily) in either standby-active, low mode (standby while connected to a network, if this is available) or standby-passive mode. This is the assumption used below.
The following table shows how much electricity TVs use per year by screen size.
|TV size||Result category||Annual electricity consumption|
|19 inch TV||Average||32.43 kWh|
|Most common||33 kWh|
|24 inch TV||Average||38.09 kWh|
|Most common||38.1 kWh|
|32 inch TV||Average||53.81 kWh|
|Most common||51 kWh|
|40 inch TV||Average||64.6 kWh|
|Most common||58.8 kWh|
|43 inch TV||Average||82.96 kWh|
|Most common||112 kWh|
|50 inch TV||Average||130.95 kWh|
|Most common||136 kWh|
|55 inch TV||Average||140.85 kWh|
|Most common||151 kWh|
|65 inch TV||Average||169.47 kWh|
|Most common||185 kWh|
|70 inch TV||Average||205 kWh|
|75 inch TV||Average||203.36 kWh|
|Most common||206 kWh|
The amount of electricity a TV uses increases with size. However, there is one expectation. The study shows that, on average, 75 inch TVs are slightly more efficient than 70 inch TVs.
75 inch TVs use 203.36 kWh of electricity per year, on average.
The most common 75 inch TV consumes 206 kWh, with the lowest consumption being 165.7 kWh.
These figures are for annual consumption, next let’s briefly take a look at hourly consumption.
How much electricity does a TV use per hour?
On average, in On mode, TVs use 0.0586 kWh of electricity per hour.
75 inch TVs use 0.1145 kWh of electricity per hour, on average, when On.
On average, when in On mode:
- 70 inch TVs use 0.1091 kWh of electricity per hour (p/h).
- 65 inch TVs use 0.0947 kWh of electricity p/h.
- 55 inch TVs consume 0.077 kWh of electricity p/h.
- 50 inch TVs use 0.0705 kWh p/h.
- 43 inch TVs consume 0.0478 kWh p/h.
- 40 inch TVs use 0.0341 kWh p/h.
- 32 inch TVs use 0.028 kWh p/h.
- 24 inch TVs use 0.0198 kWh p/h.
- 19 inch TVs use 0.0165 kWh of electricity per hour.
To work out how much electricity your TV uses per hour, simply use the following formula:
Hourly electricity consumption (in kWh) = TV wattage x 1 (i.e 1 hour) / 1,000
For example, the most common 55 inch TV uses 82 watts when in On mode. Using the formula, this works out at 0.082. So, the most common 55 inch TV uses 0.082 kWh of electricity per hour.
But what about when a TV is off?
How much electricity does a TV use when off?
If a TV is unplugged or disconnected from the power source, it will use no electricity.
However, all TVs, in the study of 107 of the most energy efficient TVs, use electricity on standby.
TVs use 0.5 to 3 watts of electricity when on standby.
Most TVs in the study use 0.5 watts on standby, with the average being 1.3 watts.
Get details about the cost to run a TV in Standby mode, here.
Do TVs use a lot of electricity?
TVs can use a lot of electricity.
Older TVs, such as CRT and Plasma TVs, consume a lot of electricity compared to modern, more efficient TVs.
However, even these TVs consume a relatively high amount of electricity over time.
On average, a modern efficient TV uses 58.6 watts at max power draw. This is equivalent to a standard 60W light bulb. However, larger TVs consume 3 to 4 times this amount of electricity.
Due to their high usage, TVs tend to consume a considerable amount of electricity every year.
The most common TV wattage consumption recorded in the study is 117 watts while in On mode, with 0.5 watts being consumed in standby mode. The estimated annual electricity consumption is 206 kWh.
The electricity used annually (206 kWh) by the most common TV wattage is equivalent to:
- Running a typical efficient compact refrigerator for 1 year.
- Running a standard washing machine for 6 months.
- Boiling a kettle 2,922 times.
Ultimately, depending on usage and wattage, TVs use a considerable amount of electricity.
With this in mind, let’s take a look at the most energy efficient TVs on the market.

While the average wattage for modern TVs is quite low, the amount of electricity TVs consume is high due to their regular usage.
The energy efficiency of TVs has improved substantially over the years. However, TV size and resolution has increased substantially too. And as a result, the amount of electricity TVs consume remains considerable.
I hope that by listing the most energy efficient TVs you can make a smarter choice, lower your electricity bills and reduce your carbon footprint.
