Plasma vs LED: TV Power Consumption and Electricity Cost
TV Electricity Cost Calculator
Use the following calculator to know how much will cost you a television in electricity over a year and compare it to an LED or Plasma TV.
As shown in the chart, the power consumption of a plasma television is higher than an LED television. The difference is more noticeable for big televisions.
A plasma TV consume significantly more power than an LED TV because each gas cell need to be excited enough to produce a bright color. In an LED display, the light is independent and shared across all the pixels so a more efficient way to produce the light can be used.
The data displayed is the average case scenario; the power consumption varies depending on the content viewed and the settings of the television. The TV consumes a lot more power when displaying a very bright white screen compared to a dark one, especially for plasma televisions.
The next chart shows the yearly cost if the television is watched 5 hours per day for 365 days, at a cost of electricity of 0.11$ per kWh.
As you can see in the chart, a plasma television does cost more electricity than an LED TV. However, the resulting cost at the end of the year is not very big, about 10$ more for a 50" plasma. On a 5 years period, the total amount saved would be 50$.
As mentioned here, a plasma TV cost on average 350$ less than an LED TV for the same size. Based on this, it will take 35 years for the total cost of ownership (initial cost + electricity cost) of a plasma television to surpass its LED counterpart.
