Does Leaving the TV On Waste Electricity? – [Here’s Answer]

Are you into saving so much that you don’t even want to waste a single? If so, you must have a question: “does leave the TV on waste electricity?”

Yes, TV does consume electricity when you leave it on, but modern and smart TV doesn’t use that much power.

Leaving a giant TV on while not watching it is lazy. Hence, let’s move ahead and learn about every aspect of leaving the TV on without using it:

Does Leaving the TV on Waste Electricity?

Well, you already know that it wastes electricity. Leaving your TV on for a long period (maybe every night) does consume electricity.

It can even add many bucks to your electricity bill if you are an (especially) middle-class person. But a thing you must know is that it’s not just your TV that consumes electricity.

Other devices that we use in our daily lives, such as light bulbs, refrigerators, and air conditioners, all consume electricity. The even more interesting thing is that they waste more energy than TV if left on.

How Much Does it Cost to Leave a TV On?

Note: Although we have facts and figures, we still can’t guarantee that your TV will cost the exact same when left on as it’s just an average. Got it?

The cost of leaving your TV on depends on how much electricity it consumes. According to the US Department of Energy, an average TV uses around 0.2 to 0.5 watts of power in standby mode.

This amazing report from the US Department of energy indicates that you will have to pay extra 44 cents per month or $5.28 per year if you leave the TV on for 12 hours a day.

But leaving your TV without turning it off for a whole month will cost you more than you think. Because in most countries, the electricity bill calculation will change after more consumption, and you will be charged more.

Moreover, the size and age of your TV also affect its energy consumption. Older TVs consume more electricity than modern and energy-efficient ones.

Similarly, larger TVs require more power to operate than smaller ones. So, if you have an older or larger TV, it will consume more electricity than a new and smaller TV.

That’s why you can’t go for one specific number!

How Much Does it Cost to Leave a TV On for All Night Long?

Leaving your TV on all night long can result in a hefty electricity bill. According to Energy.gov, an average TV uses around 80 watts of electricity when turned on.

If you keep your TV on all night long, it can cost you around $0.18 per hour, which adds up to $1.44 for eight hours. If you do this every day, it would add up to $43.20 per month, which is a lot of money.

Furthermore, if you have a smart TV, it may consume more electricity than a regular TV because of its additional features and functionalities.

Therefore, it’s crucial to turn off your TV when you’re not watching it to save electricity and reduce your energy bills.

Things to understand: All the numbers mentioned above are for those dealing in dollars (More specifically, US residents). If you live somewhere else, convert them to your currency. Numbers will be almost the same.

How to Estimate the Cost of Electricity Consumption of TV Once Left On? (More In-depth)

You already have an estimate of how much your TV will cost you if turned on all night long. Now, let’s move to a more comprehensive estimation:

To estimate the cost, you can use a simple formula:

Cost = (Wattage x Hours Used) ÷ 1000 x Cost per kWh

For example, if you have a 100-watt TV and you leave it on for 10 hours a day, and your electricity rate is 12 cents per kWh, the estimated cost would be $0.12 per hour, or $1.20 per day, which adds up to $36 per month.

Now, you just need to read the power of your TV from the box of your TV (written in watts). If you lost the box, search for your TV with the exact model name and number to know its power.

After knowing power, just simply put its value in the formula with the number of hours you left it on without using it.

Don’t forget to know the “cost per kWh” in your country or region, which you will find on the electricity bill. For example, in the UK, it’s almost 16.6 pennies per kWh as of now. You can also search for it on the Internet.

Factors Affecting the Electricity Consumption of TV:

You want to know the exact amount of electricity your TV consumes when you leave it turned on. Right?

But we can’t provide you with it because many factors make your TV and its electricity consumption.

So, here are the main ones:

TV Size:

Bigger TVs use more energy to power the screen, so smaller TVs are a better choice if you want to reduce electricity usage.

TV Age:

Older TVs are less energy-efficient and consume more power compared to newer models. Consider upgrading to a more energy-efficient TV.

TV Technology:

Plasma TVs consume more electricity than LED or LCD TVs. Features like 3D or high refresh rates can also increase energy consumption.

TV Usage:

Leaving your TV on when not in use or using it for high-energy activities like gaming can increase electricity usage. Turning it off when not in use can help reduce energy consumption.

Conclusion:

So, you know that leaving the TV on while not using it wastes electricity. But you also know the cost of electricity that you are wasting every day only because of laziness and carelessness.

This must be quite stressful. Right?

Don’t sweat, and just follow our tips to reduce your electricity bills:

  • Turn off devices when not in use.
  • Use energy-efficient devices. (modern smart TVs consume less electricity, so buy one if you can afford as it’s a great investment)
  • Adjust the brightness and contrast settings on your TV to reduce power consumption.
