With the cost of living and energy prices on the rise, it is important to understand the impact of your appliance usage on your overall energy consumption. While TVs are not the biggest energy drain, they do contribute to household energy usage and costs. Modern TVs use about 50-150% less energy than their predecessors, but they still use a fair amount of electricity. The amount of electricity a TV uses depends on the model, size, and special features. On average, TVs use 50 to 200 watts of electricity, with 100 watts being a safe average consumption for modern TVs.

Modern TVs use around 50-200 watts of electricity, depending on the model and size
Modern TVs use electricity, whether they are on or off. The amount of electricity used depends on the model, size, age, and special features of the TV. On average, modern TVs use around 50 to 200 watts of electricity, with most drawing about 100 watts. This is a safe average electricity consumption to assume for modern TVs from top manufacturers.
The wattage of a TV is determined by its voltage and amperage. Most TVs use less than one amp and connect to a 120-volt outlet. To calculate the wattage of your TV, you can multiply the volts by the amps. For example, if a TV has 1.37 amps and is connected to a 120-volt outlet, it will use 164 watts (1.37 x 120 = 164).
The size of the TV also affects its wattage. Larger screens require more watts, 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 age of the TV also plays a role in its energy efficiency. Older models are less efficient and can draw anywhere from 120 to 200 watts. Modern LCD and LED TV models are designed with energy efficiency in mind and will be more energy-efficient than older models.
There are ways to reduce your TV's electricity consumption. Many modern TVs have an Eco mode that automatically adjusts the brightness of the TV, ensuring it only uses as much lighting as it needs. If your TV doesn't have Eco mode, you can manually adjust the brightness. You can also use the sleep timer function to automatically turn off the TV after a set period of time.

Older models are less efficient, drawing around 200 watts
The age of a TV plays a significant role in how efficient it is and how much electricity it uses. Older models are less efficient, drawing around 200 watts, while modern TVs are more energy-efficient, consuming around 100 watts. The older CRT models, for example, use up to 120 watts, while newer LED TVs consume 24-28 watts for small sizes and 90 watts for larger sets.
The larger the TV, the more energy it will typically consume. A 48-inch TV, for instance, consumes 80 watts of power, while a 65-inch TV uses nearly 115 watts. The type of TV also affects its power consumption. Plasma TVs, for example, consume up to 500 watts, while OLEDs consume 60-75 watts. The latest LCDs and LEDs consume nearly 70-200 watts and 50-100 watts, respectively.
The amount of time the TV is used also impacts power consumption. Watching TV for 2 hours a day on a 100-watt TV will use 1.4 kilowatt-hours of electricity per week or 6 kilowatt-hours per month. Increasing TV usage to 3 hours per day will result in a monthly electricity consumption of 9.1 kilowatt-hours.
There are ways to optimise energy usage and reduce costs. Energy-efficient features and settings adjustments can help lower power consumption. TVs with an Energy Star rating, for example, are 25% more efficient than conventional TVs. Smart TVs can be connected to smart speakers for easy remote control and scheduling, allowing the TV to be switched off when not in use. Additionally, using solar generators or installing solar panels can be a solution to reduce electricity bills.

TVs with larger screens require more energy, with some using up to 500 watts
The power consumption of a TV depends on its type, size, and technology. In general, as the screen size increases, the power consumption (in watts) also increases. Older models like CRT and Plasma TVs are known for their high power consumption, often using several hundred watts of electricity. For example, CRT TVs draw up to 120 watts of electricity, while plasma TVs can consume up to 500 watts.
Newer models, such as LCD and LED TVs, have been designed to be more energy-efficient, reducing electricity costs and environmental impact. A typical modern TV consumes between 50 and 150 watts, depending on the screen size and model. For instance, a 32-inch LED TV may use 30-55 watts, while a 32-inch LCD TV might consume 50-85 watts.
OLED TVs, which are newer than LED TVs, tend to be more power-hungry than LED models. They consume twice as much power as older plasma TVs and slightly more than LEDs. However, it is important to note that power consumption is not solely dependent on TV technology but also on screen size and brightness. For example, an 8k TV will require more power than a 4k TV due to having four times the number of pixels. Similarly, as the brightness level is raised, power consumption and costs increase.
While TVs with larger screens tend to require more energy, there are ways to reduce their power consumption. Energy-saving features, adjustable settings, and portable power stations can help lower energy usage. Additionally, modern TVs often come with energy-saving modes, and some are Energy Star-certified, which means they are 25% more efficient than conventional TVs.

Smart TVs can help reduce energy consumption by connecting to other smart devices
TVs can be huge power-sucking devices, and their size is a major factor in how much energy they consume. Generally, the bigger the screen, the more energy your TV will consume. Modern flat-screen TVs consume anywhere between 50 and 150 watts of electricity, with older models drawing as much as 200 watts.
Smart TVs are designed for intelligent homes, and connecting to a smart electronic device is one of the best ways to reduce energy consumption. They can also be connected to smart speakers, allowing you to control the TV remotely or set it on a schedule for DVR purposes. However, be aware that just because a TV is labelled "smart" doesn't mean it's the most energy-efficient model available.
Smart TVs with light sensors can automatically adjust the screen's brightness based on the ambient lighting conditions. This can help reduce energy consumption without interrupting your viewing experience. Additionally, lowering the backlight on your TV can significantly reduce energy usage, especially if the TV is positioned away from direct sunlight.
When purchasing a new TV, look for the Energy Star rating. These TVs are 25% more efficient than conventional models. LED-backlit TVs and OLED TVs are also excellent choices for energy efficiency, consuming less power than traditional LCD screens.

To save on electricity, use the sleep timer function to automatically turn off your TV
TVs consume varying amounts of electricity depending on their type, age, size, usage, and vampire power. On average, a TV uses around 620,000 watt-hours annually, with most modern TVs drawing around 50 to 200 watts of electricity. Older models, such as CRT TVs, can consume up to 120 watts, while newer LCD and LED TVs are more energy-efficient, typically using 50 to 150 watts.
To optimize your TV's energy usage and reduce your electricity bills, consider using the sleep timer function. A sleep timer is a built-in feature in most modern televisions that allows you to set a specific duration after which the TV will automatically turn off. This simple concept has far-reaching benefits for both energy conservation and user convenience. By using the sleep timer, you can ensure that your TV doesn't run unnecessarily, reducing your carbon footprint and saving you money.
Sleep timers are distinct from auto power-off features, which activate after a period of inactivity. With a sleep timer, you manually set the duration for which you want the TV to remain on. This distinction is important to maximize your TV's energy-saving capabilities. Additionally, sleep timers can promote better sleep habits and overall well-being, ensuring that you don't wake up to a blaring TV in the middle of the night.
To set up a sleep timer on your TV, simply access the settings menu, locate the sleep timer option, and select your desired duration. The exact steps may vary depending on the brand and model of your TV, but most modern TVs provide easy access to this feature through the remote control or on-screen menu. Some smart TVs, such as those from Samsung, LG, Sony, and Vizio, offer advanced sleep timer options, including gradual volume reduction and integration with other smart home devices.
