Modern TVs consume 50-200 watts of electricity, depending on the model, size, and features
Modern TVs consume electricity, whether they are on or off. The amount of electricity consumed depends on the model, size, and features of the TV. On average, modern TVs use around 50 to 200 watts of electricity. A larger screen TV will require more power, with some larger screens requiring up to 200 watts. For example, a 32" LED TV will consume 30-55 watts, while a 32" LCD TV might consume 50-85 watts.
The power consumption of a TV can make a big difference in energy bills, especially if you have multiple TVs or larger-screen TVs. The average TV uses around 620,000 watt-hours annually. This is less than the average refrigerator, which uses between 350 and 780 watts. However, the energy use of TVs can add up quickly, especially if they are left on when not in use.
There are ways to reduce your TV's electricity consumption. One way is to turn off your TV when you're not actively watching it. If you need background noise, you can turn on the radio or listen to a smart speaker instead. You can also use the sleep timer function to automatically shut off the TV after a set period of time. If you know you won't be using the TV for a while, unplugging it can also help reduce energy consumption.
Another way to reduce energy consumption is to connect your TV to a smart electronic device or smart speaker. This allows you to control the TV remotely or set it on a schedule. You can also look for Energy Star-rated televisions, which meet strict efficiency standards and use less electricity in sleep, idle, and active modes.

Older TV models consume more energy than newer ones
The power consumption of a TV depends on several factors, including the TV type, age, size, usage, and vampire power. Older TV models, such as the CRT (cathode-ray tube) TVs, consume more energy than newer ones. These older TVs are bulky and can consume up to 120 watts of electricity, while still being popular among gamers for their lack of motion blur or input lag.
Newer TV models, such as LEDs and LCDs, are more energy-efficient. A 32-inch LED TV, for example, consumes around 30 to 55 watts, while a 32-inch LCD TV consumes around 50 to 85 watts. The latest LCDs and LEDs consume approximately 70 to 200 watts and 50 to 100 watts, respectively.
OLEDs, which are known for their superior picture quality, consume more energy than LEDs. A 55-inch OLED TV consumes around 98 watts per hour, while a similar-sized LED TV consumes only 57 watts per hour. A 65-inch OLED TV will use 116 watts per hour, compared to 88 watts for an LED.
While TVs can contribute to an increase in electricity bills, other factors should also be considered. For example, running an air conditioner during heatwaves can also impact energy costs. Additionally, while newer TVs are more energy-efficient, the overall energy savings from switching to a newer model may not be significant compared to other household energy usage.

TVs still use electricity when they're turned off
The amount of electricity a TV consumes depends on its type, age, size, usage, and vampire power. Most modern TVs consume nearly 100 watts of power, with a typical range of 50 to 150 watts. However, older CRT TVs can consume up to 120 watts, while plasma TVs can consume up to 500 watts. The latest LCDs and LEDs consume nearly 70-200 watts and 50-100 watts, respectively.
Even when turned off, TVs can still consume a small amount of electricity, known as "vampire power" or "standby power". This power is used to keep the device in a standby mode, allowing it to be turned on quickly and to power features such as a clock or indicator LED. While the power consumed by a TV in standby mode is relatively small, it can add up over time, especially for older models.
To completely prevent a TV from drawing power when not in use, it needs to be unplugged from the power outlet. However, unplugging a TV every time it is turned off may not be practical or convenient, and it may cause wear and tear on the electrical socket. As an alternative, some surge protectors and UPS units have a "main" outlet that can detect when the TV is turned off and cut power to all connected devices, preventing them from consuming standby power.
While modern appliances have fairly negligible standby power consumption, it is worth checking your home for older devices that may still draw a significant amount of power when turned off. Additionally, you can refer to the user manual or guide to find out the specific power consumption of your TV when it is turned off, as this information is typically provided by the manufacturer.

Quick Start mode on Smart TVs can increase energy consumption
The power consumption of a TV depends on various factors, including the type, age, size, usage, and vampire power. Modern TVs are more energy-efficient than older models, with LCD and LED TVs being the most energy-efficient options. However, the larger the screen size, the more power the TV will require.
Quick Start mode on Smart TVs is a feature that allows the TV to switch on quickly and tune into a favorite channel without having to wait for a few seconds. While this mode may seem convenient, it can increase energy consumption. When a TV is in Quick Start mode, it remains in sleep mode when not in use, consuming a small amount of energy continuously. This can add up over time, resulting in higher electricity bills and increased carbon dioxide emissions.
To save energy and reduce power consumption, it is recommended to turn off the Quick Start feature when not in use. Turning off the TV completely will also help reduce energy usage. Additionally, lowering the backlight and adjusting the brightness based on ambient lighting conditions can significantly reduce power consumption.
It is worth noting that some Smart TV models, such as those from Samsung and LG, have found ways to support smart wake features without significantly increasing standby power levels. However, for other models, enabling smart wake features can cause a TV's annual electricity consumption to increase by up to 75%.
By making small changes to TV settings and choosing energy-efficient models, users can reduce their energy consumption, lower their electricity bills, and contribute to a more eco-friendly home.

Energy Star-rated TVs lower electricity consumption
Television consumption has become a cornerstone of home entertainment, with activities such as binge-watching series, late-night gaming, and streaming contributing to increased screen time and energy usage. While modern TVs generally consume nearly 50 to 200 watts of electricity, with some larger models consuming up to 500 watts, there are ways to lower electricity consumption.
One effective way to reduce energy usage is to choose a television with an Energy Star rating. Energy Star-rated TVs are designed to be energy-efficient, saving energy across different usage modes such as sleep, idle, and on. These TVs are certified to be, on average, 25% more energy-efficient than conventional models. By opting for an Energy Star-rated TV, you can significantly lower your electricity consumption associated with television usage.
Energy Star-rated TVs come with pre-set picture views such as "vivid," "sports," or "cinema," ensuring energy savings without compromising on visual quality. Additionally, these TVs often feature the latest "must-have" technologies, including high dynamic range (HDR) for enhanced colours and contrast levels, and internet connectivity, also known as "Smart TVs," providing access to popular streaming platforms.
When selecting an Energy Star-rated TV, it's important to consider the size of the television relative to your viewing distance and room size. While a TV that's too small can cause eye strain, a larger TV isn't always the best choice. By measuring your viewing distance and dividing it by two, you can determine the recommended UHD TV diagonal length. This ensures an optimal viewing experience and helps prolong the time between TV upgrades.
In addition to choosing an Energy Star-rated TV, there are other ways to further reduce energy consumption. Customizable brightness settings can have a notable impact, as lowering the brightness can reduce power usage. Additionally, consider the energy source used to power the TV, as switching to renewable energy sources can significantly lower the environmental footprint of your TV's energy use.
