A bigger screen needs more power, so a list of the lowest-wattage televisions would simply be a list of the smallest ones. To make the comparison fair, this ranking divides each television's on-mode power by its screen area, using the diagonal size and assuming a standard 16:9 panel. The result is the watts needed per 100 square inches of picture: lower means a more efficient television, whatever its size.
ENERGY STAR also lists the annual energy use reported for each model, which includes time in standby, and that is the figure used for the yearly cost. The table shows both, along with the screen size, so you can see which televisions are efficient for their size and what a particular size will cost you.
Choose your state or enter your rate in the calculator, and your own television's yearly kWh if you know it, to see what each model would cost or save.

How this is calculated
- Yearly cost = the model’s ENERGY STAR annual kWh × your rate. Ten-year cost keeps today’s rate; prices will change.
- Savings = (your current television’s yearly kWh − the new one’s) × your rate. Find yours on the yellow EnergyGuide label or measure it with a plug-in meter.
- Statewide averages are not your utility’s tariff. Use the rate on your bill for a closer number.

How we ranked them
Models come from the ENERGY STAR certified televisions list published by the U.S. EPA. We keep only the current listing for each model, and only models that state an annual energy figure. They are ordered by on-mode power per screen area: the on-mode watts divided by screen area (diagonal squared, for a 16:9 panel), so a small screen does not win just by being small.
As reported to ENERGY STAR, including standby. Your use will differ with how many hours a day the television is on and the picture settings you choose. Prices are U.S. EIA statewide residential averages. We do not test products and we do not show retailer prices. See the methodology and data sources.
What to look for in TVs
Size and cost move together
Within the same technology, the yearly cost rises quickly with screen size, because screen area grows with the square of the diagonal. Choosing the size you will actually use is the single biggest saving.
Picture settings matter as much as the model
The brightest picture modes can draw far more power than the standard or an energy-saving mode. Turn on automatic brightness if the television has it, and avoid the showroom-style modes in a dim room.
Standby and network features
The annual figure includes standby, and a television that stays connected to the network or has a quick-start mode can use more when it is off. Check the settings and turn those features off if you do not use them.

How are these TVs ranked?
Models are ordered by on-mode power per screen area from the ENERGY STAR certified product list, using only models that list an annual energy figure. As reported to energy star, including standby. your use will differ with how many hours a day the television is on and the picture settings you choose. We do not test products and we do not show retail prices.
What screen size is it?
ENERGY STAR lists a 64.53-inch viewable diagonal for this television.
How much power does it draw when it is on?
ENERGY STAR lists 84.55 W in on mode. The annual figure also counts standby, so it is not just on-mode watts multiplied by your viewing hours.
Is it worth replacing an old television?
It can be, if the old one uses a lot more electricity. Enter its yearly kWh in the calculator above to see the saving per year and over ten years, or use the television replacement calculator for the full comparison.
Which TV size is the most energy efficient?
Smaller screens use less power in total, but efficiency is about power per screen area. The table shows watts per 100 square inches for every model, so you can compare a 43-inch and a 65-inch television fairly and then decide what size you need.
