How Many Watts Does a TV Use?
Modern LED TVs are known for their energy efficiency. Typically, they use between 30 to 100 watts, depending on the screen size. Whereas older LCD TVs consume slightly more, approximately 50 to 200 watts. Plasma TVs, known for their larger screens and vivid displays, are higher on the consumption scale, using about 200 to 500 watts. The latest OLED TVs strike a balance between superb picture quality and energy efficiency, with wattage generally falling between LED and plasma TVs. Understanding how many watts is a TV can be key to managing your household’s energy efficiency and costs.

Which is the Most Energy Efficient TV?
The most energy-efficient TV is the LED, which overall has the lowest wattage across the board. This mostly has to do with the backlighting source, which comes from the LED bulbs, which can allow the TVs to be thinner and require much less energy. The LED TV uses two-thirds the amount of electricity that an LCD TV does, and one-third is used by a plasma screen.
How Much Electricity Does a TV Use? – Cost
Let’s start with an example you own a 55-inch LED TV that has a rated power of 120 watts. For the whole month, you use that LED TV for 50 hours a month, and pay $0.13 per kilowatt-hour on your electricity bill (the national average).
Power Consumed (kWh) = Wattage of appliance (kW) x hours used
For your TV:
- Power = 120 watts
- Hours used = 50 per month
Power Consumed by LED TV per month = 120 watts x 50 hours = 6000 watts hours
As we saw above, we need to convert to kWh to see how much it will cost us to run for the month, so you’ll have to divide by 1000 to get kWh.
= 6 kWh
Total cost to run 55-inch LED TV for the month: 6 kWh x $0.13 = $0.78 per month
Now remember that number and imagine how much it will cost if you watch TV for much more than 50 hours per month. You can also see how if you have multiple TVs in your home quickly that can add up with TV energy consumption.

Tips and Tricks for TV Energy Consumption
There are some especially bad habits we have with TVs, as there are many different ways you can needlessly use them and waste energy. Luckily, there are tricks you can do to save some energy when using a TV and hopefully, you can save a couple of dollars by using them!
- Set a sleep timer – We all know how soothing a TV can be for a nap or nighttime rest, but time spent asleep and not watching is draining your energy.
- Use a power strip for devices – TVs are notorious for being vampire appliances, which are appliances that drain energy even when they are off. That is because stand-by mode still uses energy, and will only stop when completely unplugged. Plug all of your devices into a power strip and unplug it when not in use.
- Upgrade your TV – If you have an older version, you may be running at a much higher wattage, whereas newer TVs tend to be much more energy efficient than they used to be.
- Use Energy Saving Mode – Many new TVs offer energy-saving mode, which will automatically adjust your TV settings to optimize energy.
