TV Electricity Cost Calculator
Use the following calculator to estimate the annual electricity cost of a television as defined by size, viewing habits, electricity cost, and TV technology.
When picking out a TV, electricity consumption is less of a concern than it once was. TVs have gotten more efficient in recent years, and since nearly all TVs currently being sold use LED lighting, which is less demanding than plasma, most people have very minimal electricity bills attached to their TVs.
That doesn’t mean there are no considerations at all. Different sizes demand a different amount of power, and so larger TVs will cost more to run (though still not that much).
What’s more, all the electricity that goes into a TV is turned into heat. This can create issues for cooling, particularly in areas with extreme temperatures in summer.
The Relationship Between Electricity Cost & Size
There is a clear relationship between the size of a TV and its power consumption, and therefore how much it costs to run. Take a look at these images, which use figures from 2013 (the numbers will be similar for 2015 models) to demonstrate the links.
The axes are different, but the distribution does not change. It’s also worth noting that even the largest LED TVs do not cost a lot to run each year, so you shouldn’t worry about that too much when deciding on a TV.
Something to keep in mind is that almost all the electricity your TV uses ends up becoming heat. In winter, this isn’t a big issue. The heat generated by the TV just ends up (slightly) lowering the amount of heating that your heater has to do.
In summer, though, or in areas that are warm year round, the extra heat can be a problem. In essence, it works against any cooling you’re doing, so you’ll be spending a bit more on air conditioning, or else suffering through more heat in order to watch TV.
If this extra heat is a big problem for you, you may want to make energy consumption one of the things you look at before diving in and buying a TV.
Two tips for reducing power consumption
- Lower the backlight setting. The backlight is by far the biggest drain on your power, and the lower you can get your backlight, the less power your TV will consume. Placing your TV in a dark or dimly lit environment will help you avoid needing a bright backlight.
- Turn the TV off. It may sound basic, but some people leave their TVs running all the time. Leaving a TV on constantly will result in much higher costs than if you turn the TV off.
The bigger or brighter your TV, the more power it will take to run. While even large, bright TVs don't consume that much power, the easiest ways to reduce the amount of energy your TV consumes is to go smaller, go dimmer, and turn your TV off when it is not in use.
