Almost half of U.S. households own three or more televisions. With the average TV getting larger and consuming more energy, the TVs in your household could be using as much electricity as your refrigerator.
It is estimated that about 33 million televisions will ship in 2013. More than 19 million of these will be greater than 40 inches in size. With televisions getting bigger and using more energy, it’s no wonder that most consumers say that energy efficiency will be a factor in their next television choice. Look for the ENERGY STAR label to save energy, save money, and help protect the climate.
ENERGY STAR certified televisions are on average, over 25 percent more energy efficient than conventional models, saving energy in all usage modes: sleep, idle, and on. The label can be found on everything from standard TVs to large screen TVs with the latest features like 3D and internet connectivity. Many models that earn the ENERGY STAR incorporate LEDs, the latest in screen backlighting technology.
Saving energy with ENERGY STAR certified home entertainment products helps protect the climate. A home equipped with TVs, a Blu-Ray player, a compact audio system, and a home-theatre-in-a-box that have earned the ENERGY STAR, can save more than $200 over the life of the products. If each TV, DVD player, and home theatre system purchased in the U.S. this year earned the ENERGY STAR, we would prevent more than 2.2 billion pounds of greenhouse gas emissions every year, equal to the emissions from more than 200,000 cars.

Televisions originally qualified for the ENERGY STAR label in 1998. ENERGY STAR certified televisions must consume 1 watt or less in Sleep Mode and On Mode power requirements vary according to screen area. External power supplies (EPS) packaged with TV products must meet level V performance requirements under the International Efficiency Marking Protocol and include the level V marking.
Today’s flat screen televisions that are sold in the U.S. are Liquid Crystal Displays (LCDs), plasma or OLED TVs.
Digital televisions come in two subgroups, which are differentiated by sharpness of picture, usually described as “lines of resolution.”
Compare contrast ratios. Contrast ratio is a measure of color representation (how the color information appears against a dark background). The higher the number, the better the color representation.
There are two ways that a TV picture can update itself to display moving images. One way is by using an interlaced signal and the second is by using a progressive scan signal. An interlaced signal, which is the method used by the standard analog screen, updates half of the scan lines (i.e. every other scan line) at a time (typically every 1/60th of a second, though some panels can update faster). A progressive scan signal updates all of the scan lines every 60th of a second. So progressive scan technology creates a sharper picture with less flicker.
The term “pixel” is shorthand for “picture element”. A pixel is the smallest item of information displayed on a television screen. Think of pixels as the tiniest dots that the picture is made of. A megapixel is one million pixels.
The ABC feature is a self-acting mechanism that controls the brightness of the TV relative to the brightness of the room in which it is located. The ABC feature is intended to enhance the viewing experience and also save energy.
Local dimming is different than ABC. Local dimming typically occurs in LED-backlit LCD TVs when sections of the LED backlighting are turned off or dimmed to help produce deep blacks and save energy.
Increasingly, TVs can be connected to the Internet over Ethernet or Wi-Fi. Network-connected TVs allow viewers to download or stream content from the Internet to their TVs. These Smart TVs can have varying levels of ability to run apps, display interactive on-demand content, and provide access to other Internet-based programs in addition to providing traditional broadcasted television.
Many TVs are now shipping with pre-set picture settings that viewers can select, such as ‘vivid,’ ‘sports’ or ‘cinema.’ These picture settings reflect changes in the brightness and contrast ratio to enhance the content in a specific manner. The default picture setting is the setting that has been used to earn the ENERGY STAR. To ensure you continue to see energy savings, make sure you use the ENERGY STAR setting as much as possible.
Some technologies are emerging that allow you to watch live and recorded programming on any TV in a home, without needing additional, or any, set-top boxes. In one instance, RVU™ (pronounced “R-view”) is a client/server-based technology that allows a central set-top box to send live or recorded programming to various consumer electronics, including TVs, without the need for additional set-top boxes in each room. In other cases, manufacturers are working with programming providers to offer limited service on their TVs without the need for a set-top box at all.
These are the top FAQs related to Televisions and the ENERGY STAR program.
