Do you ever wonder Do old TVs use more electricity? Because they can do so much more than traditional televisions, smart TVs are becoming more and more common. They offer Internet connection and the capacity to operate a variety of apps, making them comparable to a smartphone or tablet.

Do old TVs use more electricity

Smart TVs often don’t consume more energy than regular TVs. However, smart TVs typically need a little bit more processing power to provide you with the best user experience and visual quality. Your smart TV will use more power with the more sophisticated settings you choose.

Do old TVs use more electricity?

Generally speaking, yes, as they had tubes or valves that needed power from a 6-volt rail supplied by a transformer to heat their filaments. The cathode ray tube needed filament element power and around 20,000 volts of low current to activate the electrostatic properties of the CRT. The tubes/valves also needed a high voltage to drive the electronics. Transistor technology, LED screens, and other technologies that consume much less current are used in modern TVs.

What Is a Smart TV?

Smart TVs use your home network to connect to the Internet. They are capable of establishing a wireless or wired Ethernet connection. For smart TVs, there is no standardized operating system. The TV you buy will determine what you get. You should check out each model to determine which offers access to applications and services, then select the one best for your home.

These TVs allow users to play games, check social media, stream content from Netflix or Hulu and connect to other devices in the home. They provide a wide range of options. Even Alexa and Google Assistant can use them. Thanks to technology, homes may now incorporate a wide range of electronic products, including TVs, lighting, door locks, and more. Frequently, your smart TV may be used to control all of these appliances.

How Much Electricity Does Television Use?

The amount of electricity a television requires depends on several variables. Your TV’s age is one important consideration, and the sort of display is another. These elements significantly impact how much energy your TV uses, whether it’s a smart TV or a standard one.

The Federal Trade Commission mandates that all televisions built-in 2011 or later display an EnergyGuide label to indicate how many kilowatt-hours a TV uses and how much it costs to operate. If the television was sold in 2011 or later, you may find out how much energy it consumes.

Black EnergyGuide labels provide these estimates based on five hours of use each day and a cost of $0.11 per kilowatt-hour. You may find out your power company’s price per kilowatt-hour and how many hours you watch TV each day to get a more accurate idea of the cost of your television.

Looking at the back panel of an older television should allow you to determine its wattage. The wattage will be shown by a number with a “W” after it. To calculate your kilowatt-hour rate, multiply that amount by the number of hours your TV is on each day and divide the result by 1000.

Do Smart TVs Use More Energy

Smart TVs often don’t consume more energy than regular TVs. If you compare the EnergyGuide ratings for the Toshiba 32″ Class LED 720p HDTV and the Toshiba 32″ Class LED 720p Smart HDTV Fire TV Edition, the smart TV is predicted to cost $6 per year on 50 kWh, whereas the normal TV is predicted to cost $8 per year on 59 kWh.

Both satellite and cable TV still require a box, whether you use one or the other. If you use a game console, you will also need to connect it. However, smart TVs generally do not use more energy because they are more sophisticated. Because the smart TV uses an Internet connection, it will consume some energy from the connection to your router.

Tips to Decrease the Energy Consumption of Your TV

Whether you have an older television model that consumes more energy or a modern energy-efficient model, it is always a good idea to reduce your power cost.

Here are some strategies for reducing the amount of electricity your TV uses:

  • Verify the Energy Star rating before you purchase a new TV.
  • The most energy-efficient displays are OLED ones.
  • In comparison to most flat-screen solutions, plasma TVs utilize more energy.
  • Reduce the brightness of your TV in the settings to save electricity.
  • Turn off your TV’s “always-on” functionality to prevent it from consuming power when it is off.
  • When not in use, switch off the TV.
  • Even though most TVs are energy-efficient today, you may still reduce your electricity costs by using these tricks.


I have explained all aspects about Do old TVs use more electricity? The fact is that a larger screen will consume more energy regardless of the type of television you have. It will consume more energy than a 32-inch screen if you insist on installing a large TV in your family room. If you go this way, you can reduce the brightness to save money and ensure the TV is turned off when not in use.

The kind of screen is still another important element. The most energy-efficient displays are now OLEDs, with LEDs coming in second. Your TV will use more energy if its plasma or CRT display is older.

You won’t consume more energy if you have a smart TV, but you will have to pay membership fees to enjoy some streaming capabilities. You won’t be able to stop your cable service if you wish to preserve your channel lineup. You might not have a choice in the future because smart TVs account for an increasing share of TV sales each year. Smart TVs won’t consume more energy than regular TVs, so you may use them as usual.

Frequently Asked Questions

Are smart TVs energy-intensive?

When the power company determines your monthly payment, it converts the typical smart TV’s 1.0 amps per hour usage to kWh (kilowatts per hour). Depending on the technology, efficiency rating, and screen design, 60″ smart TV prices may be slightly more or surprisingly lower.

Does unplugging a TV reduce energy use?

A computer, modem, monitor, TV, phone charger, or cable box all take a large amount of electricity even when not in use, in contrast to your coffee maker or microwave, which are unlikely to make a big difference.

How much does an hour of TV use cost?

The average cost of operating a modern TV is $0.0088 per hour, ranging from $0.0015 to $0.0176. The annual cost of keeping a TV continuously on standby ranges from $0.66 to $3.94.

Does watching TV cost more power?

Though it won’t considerably raise your electricity bill, leaving a modern TV in standby mode is still a waste of money. Here’s what you should do to reduce electricity use whether the TV is on or off. At night, turn the TV off completely (and other entertainment center devices).
