Why buy an energy efficient TV?

Energy efficient TVs are a brilliant shout to provide all your entertainment, whilst saving on your energy use.

In 2023 the UK population spends around 5 hours every day watching TV. This may be active watching or just having the TV on for a bit of background noise. Either way, you’re using electricity.

Going for a more energy efficient television equipped with the latest technology is a win-win for you and your electricity use.

Do TVs use a lot of electricity?

TVs don’t use a massive amount of energy compared to other products. Roughly, we’re talking 4% of your households total energy use.

Appliances that use more energy than your TV include tumble dryers, electric fires and electric ovens.

Appliances that use less energy than your TV include energy efficient kettles and microwaves.

Roughly on par with your TV is the energy use of a fridge freezer and dishwasher.

All of the above depends on how much you actually use the appliances and what kind of energy consuming models you have.

How much electricity does a TV use?

Before we get into the best models, how much energy does a TV use anyway?

How much electricity a TV uses depends on a number of factors. The main factors include:

• TV wattage – This is how much electricity is required to power it. This can range from 50W to 300W
• Size – Bigger screens will use more electricity
• Screen type – Most TVs sold in 2023 are either OLED, QLED, LED or LCD.
• Resolution – The amount of energy a TV uses increases with resolution. Televisions equipped with 4K, 8K, Full HD, Ultra HD and the like will use more energy. You also have HDR (High Dynamic Range) and SDR (Standard Dynamic Range).
• On time – How long it’s used for per day (5 hours is the UK average)
• Smart tech – automatic power off, sleep mode, local dimming

According to ecocostsavings.com, the average TV will use 106kWh of electricity per year.

With the price per kilowatt (kW) currently at 0.34p, this energy use would cost you just over £34 per year. That’s for the average TV.

If you have a larger, high resolution TV this will cost you more.

For example, a 55″ Ultra HD TV with HDR may cost you around £68 per year to power.

Taking it up further, a 75″ 8K HDR TV could cost you £200 a year to use.

Interesting to note, a TV using HDR, instead of SDR, requires around twice the amount of electricity.

Work out the cost of running a TV

To work out the electricity cost of any TV all you need is the wattage, the price of electricity you pay and how many hours you watch TV for.

Just follow these steps. I’ll use a TV with a power rating of 80W as an example.

1. Divide wattage by 1000 to get the kW per hour rating – For example, 80W / 1,000 = 0.08kWh
2. Multiple kWh by your electricity unit rate – The rate I currently pay for electricity is 0.34p per kWh, so 0.08kWh x 0.34p = 0.0272.
3. Multiple this by 100 to get per hour cost in pence – 0.027 x 100 = 2.72p
4. Multiple cost per hour by how many hours you watch TV a day – 2.72p x 4 hours = 10.88p per day
5. With the cost per day you can get estimates for weekly, monthly and annual costs – For example, weekly costs in my example would be 76p, monthly costs would be £3.26 and annual cost would be £39.71.

How energy efficient TVs save money

The most energy efficient TVs on the market now use LED technology.

Just like your lightbulbs, LEDs are a much more efficient way of providing light. Plasma TVs (remember them) and LCDs are lit up using different, more energy intensive technology. This is why they are now being phased out to be replaced with LED, QLED and OLED.

Energy efficient TVs use less power than traditional TVs, which means they cost less to operate on a pixel by pixel basis.

Even though some more eco friendly TVs will cost more to run per year, they will actually use less watts per inch. The increase in costs come from the fact that the TVs are larger.

TV Energy Rating Labels

As of March 2021, there’s a new Energy Rating label system in operation throughout the UK and EU.

Instead of A+++ to D, it’s now a more easy to understand A-G rating. The closer the rating is to A, the more energy efficient the appliance is.

Different appliances have a different energy rating system. For example, energy efficient fridge freezers are not judged on the same system as eco dishwashers and washing machines.

Why do TVs have low energy ratings?

Most TVs on the UK market now have an energy rating of E or lower.

Many TVs have been downgraded in energy rating since the change in labelling system. Previously, a TV using 110W of power could be classed as A. But now, the same TV would be G.

To get a 55″ TV to the new A standard, it would have to consume less than 30W of electricity.

This leaves TV manufacturers plenty of room for improvement.

This is because a TVs energy rating is based on energy use per inch of the display screen rather than total energy consumption.

This makes it possible to compare TV energy efficiency of small and large screen sizes.

All new TVs sold on the market will have an Energy Rating label so you can check this out.

Improve your efficiency with other appliances…

As well as your TV, it’s a wise choice to invest in other energy efficient appliances when the time is right.

Everyday items such as energy efficient kettles are good, but you might want to invest in instant hot water taps that come with good efficiency ratings.

There are lots of other appliances you can look into when it comes to running a more sustainable kitchen.
