In today’s world, we are surrounded by various gadgets, and one of the most common is the television. Whether it’s catching up on the latest shows, watching a sports game, or relaxing with a movie, the TV is central to many households. But have you ever stopped to think about how much electricity your TV uses? While it might not seem like a big deal, understanding your TV’s energy consumption can help you better manage your household energy use, save on your electricity bills, and even make smarter decisions about your energy sources—like switching to solar power.

How Many Watts of Electricity Does a TV Use?

TVs typically consume between 50 and 200 watts of power, depending on the size and technology. Newer models, such as LED and LCD TVs, tend to be more energy-efficient compared to older models like Plasma and CRT TVs. These older TVs use significantly more power, especially plasma TVs, which were known for their higher energy consumption.

In most cases, a TV draws less than one amp of current from a standard 120-volt outlet, which is common in households. However, how much power your TV actually uses depends on how long you keep it running each day.

Impact of Viewing Time on Electricity Use

The more you watch TV, the more electricity it will consume. For example, the average American adult watches TV for about 3 hours per day. While your TV’s wattage gives an idea of how much power it draws, it’s really how many hours you use it that makes the biggest difference in your electricity bill.

Here’s a simple breakdown of energy consumption based on different daily usage times for a 100W TV:

  • 1.5 hours per day: This results in about 1.05 kWh per week, 4.55 kWh per month, or roughly 54.6 kWh per year.
  • 3 hours per day: You’ll consume 2.1 kWh per week, 9.1 kWh per month, and 109.2 kWh per year.
  • 4.5 hours per day: That adds up to 3.15 kWh per week, 13.65 kWh per month, and 163.8 kWh per year.

How Different TV Models Impact Power Consumption

If your TV consumes more or less than 100W, you can adjust the calculations accordingly:

  • For a 50W TV, running it for 3 hours a day would use about 1.05 kWh per day, 4.5 kWh per month, and 54.6 kWh per year.
  • For a 200W TV, the consumption would be higher: about 2.1 kWh per day, 9.1 kWh per month, and 109.2 kWh per year.

How Much Energy Does a TV Use Annually?

The following table shows the annual consumption for TVs with different wattages, assuming they are used for 4 hours per day.

TV Wattage (W) Daily Usage (hours) Daily Energy (kWh) Annual Energy Usage (kWh)
60W 4 0.24 kWh 87.6 kWh
80W 4 0.32 kWh 116.8 kWh
100W 4 0.40 kWh 146 kWh
120W 4 0.48 kWh 175.2 kWh
140W 4 0.56 kWh 204.4 kWh
160W 4 0.64 kWh 233.6 kWh
180W 4 0.72 kWh 262.8 kWh
200W 4 0.80 kWh 292 kWh

As you can see, the higher the wattage of your TV, the more energy it consumes over time. For instance, a 60-watt TV only uses about 87.6 kWh annually, while a 200-watt TV can use up to 292 kWh if watched for 4 hours daily.

To put this in perspective, depending on your electricity rate, a 200-watt TV might cost you around $35 annually if your rate is $0.12 per kWh.

How Much Energy Do Different Types of TVs Use?

TV Type Power Consumption Energy Usage (Annual) Notes
LED/LCD TV 30W - 200W 54.6 kWh - 163.8 kWh Energy-efficient, widely used.

Plasma TV 200W - 500W 218.4 kWh - 731.4 kWh High energy use, less common now.
CRT TV 60W - 150W 54.6 kWh - 163.8 kWh Older technology, not energy-efficient.
Smart TV 60W - 200W 66.3 kWh - 218.4 kWh Slightly higher use due to smart features.

Quick Takeaways:

  • LED/LCD: Most efficient, great for everyday use.
  • OLED: Beautiful picture but uses more energy.
  • Plasma & CRT: Older models that use a lot of energy, so it’s a good idea to upgrade.
  • Smart TVs: Similar to LED/LCD, but with extra energy use due to internet connectivity.

Average Power Consumption by Common TV Sizes and Standby Power Usage

Larger TVs generally use more power, but standby mode can also contribute to energy use, even when the TV is off. Here's a look at 10 common TV sizes across different types, showing their typical power usage during normal operation and in standby mode:

TV Size (inches) TV Type Power Usage (W) Standby Power (W)
32" LED 30W 0.5W
32" LCD 50W 1W
40" LED 60W 0.5W
40" OLED 80W 1W
43" LED 70W 0.5W
50" OLED 90W 1W
55" LED 100W 0.5W
60" LCD 120W 1W
65" OLED 130W 1W
75" LED 150W 0.5W

Explanation:

  • LED TVs tend to be the most energy-efficient across various sizes. For instance, a 32-inch LED TV only uses about 30 watts during regular use, and as little as 0.5 watts in standby mode.

  • LCD TVs, although less efficient than LEDs, still perform reasonably well. A 32-inch LCD TV typically consumes 50 watts, and 1 watt in standby mode.

  • OLED TVs are more power-hungry compared to LED models. A 55-inch OLED TV consumes around 90 to 130 watts, depending on size, and typically uses 1 watt in standby mode.

Standby mode may seem insignificant, but over time, that 0.5 to 1 watt of continuous power adds up. In fact, standby power consumption accounts for a noticeable portion of annual energy usage if you leave your TV plugged in all the time.

How Much Does It Cost to Run a TV in the U.S.?

On average, U.S. residents spend about $135.25 per month on electricity, with TVs contributing a notable portion to this bill. The actual cost of running a TV depends on factors such as the TV's wattage, how many hours it's used, and where you live, as electricity prices vary greatly by state.

For example, the average U.S. electricity rate is about $0.1596 per kWh. So, if you run a 100-watt TV for 5 hours a day, you'd consume 0.5 kWh daily (100W ÷ 1,000 = 0.1 kWh × 5 hours = 0.5 kWh). Over a month, that adds up to 15 kWh, costing you about $2.39 (15 kWh × $0.1596/kWh).

Average Monthly and Yearly TV Electricity Costs by State

Below is a breakdown of the monthly and yearly costs of running a 100W TV in different U.S. states, based on their average electricity rates:

State Electricity Rate (¢/kWh) Monthly Cost (100W TV, 5h/day) Yearly Cost (100W TV, 5h/day)
California 26.69 $4.00 $48.02
Texas 13.30 $1.99 $23.86
New York 23.70 $3.55 $42.60
Florida 13.37 $2.00 $24.06
Hawaii 44.09 $6.60 $79.99
Washington 10.49 $1.57 $18.97
Massachusetts 24.81 $3.72 $44.66
Alabama 14.25 $2.14 $25.69

This table highlights the impact that varying electricity rates can have on TV operating costs. States like Hawaii and California, with their high rates, naturally incur much higher costs than states like Texas or Washington, which benefit from lower rates.

Simple Ways to Reduce Your TV's Energy Usage

Here are four practical methods to help you cut down on energy consumption:

1. Reduce Standby Time

Many people don’t realize that TVs consume power even when they're off, thanks to standby mode. A TV in standby mode can use anywhere from 0.5 to 1 watt per hour, which may not seem like much, but it adds up over time. To reduce this wasted energy, you can either:

  • Turn off the power strip when the TV is not in use.
  • Unplug the TV if it won’t be used for an extended period.

2. Adjust Brightness and Contrast Settings

Most TVs come with default settings that are brighter than necessary, leading to higher power usage. You can save energy by:

  • Lowering the brightness and contrast settings to a comfortable level for your room's lighting.
  • Using an energy-saving mode that automatically optimizes the display settings for efficiency.

This simple adjustment can reduce your TV's energy consumption by as much as 30%.

3. Upgrade to an ENERGY STAR-Certified TV

If you're in the market for a new TV, consider choosing one with an ENERGY STAR label. ENERGY STAR TVs are designed to consume significantly less electricity without sacrificing performance. On average, they use 25-30% less energy than standard models. This reduction in energy use not only lowers your electricity bill but also reduces your household's carbon footprint.

4. Use Solar Panels and Home Storage Batteries

One of the most efficient ways to reduce your overall energy usage is by switching to renewable energy sources. By installing solar panels paired with a home storage battery, you can power your TV and other household devices using the sun’s energy.

This is where SEL's home storage battery system can make a big difference. Our battery systems store excess solar energy during the day so you can use it later, even at night. This allows you to run your TV and other appliances without drawing electricity from the grid, significantly lowering your monthly energy costs and reducing your environmental impact.

With solar panels and a reliable battery storage system like SEL’s, you can essentially power your TV for free once the installation is in place. Plus, any surplus energy can be used for other household appliances, further enhancing your savings and sustainability.

How Many Solar Panels Does It Take to Run a TV?

To run a TV, you'll need to calculate the number of solar panels based on the TV's power consumption and the panel's output.

  1. Determine the TV’s power consumption: Check the TV’s wattage, usually found on the label or in the manual. For example, if the TV uses 100 watts.
  2. Find out the solar panel’s output: A standard solar panel produces around 300 watts per hour.
  3. Calculate the number of panels: Divide the TV’s wattage by the panel’s output. For a 100-watt TV and a 300-watt panel, you would need approximately 0.33 panels (100 / 300 = 0.33).

This means a single solar panel can easily cover the power needed to run a TV, assuming it’s sunny. For a reliable and efficient solar energy setup, consider our solar systems at SEL, designed to meet your needs.
