While old standards required TVs to barely sip power when turned off, starting November 1, the new standards will be launched and TVs that want to sport the Energy Star logo will have to be a bit more efficient when actually turned on. The old standard (you may want to sit down for this) only tested TVs for phantom power. In other words, to be Energy Star certified, they could use no more than than one watt when turned off. Sure, this is important considering phantom power is an issue and TVs are turned off about 80% of the time. But still, c'mon.
Luckily Energy Star sees the flaws in this and the new standards will test TVs when turned on. The power-on testing will have to be made in the default picture mode of the TV. Using the "home" setting versus the "retail" setting puts the TV in standard picture mode which is much more energy sipping. Switching to modes like "vivid" or "dynamic," which are used in stores, draws a heck of a lot more power.
With Energy Star testing for energy use when people are actually using the TVs, consumers will be able to get a better idea of just how efficient the TV is when in a mode they'll be using at home.
The amount of energy a TV is allowed to consume and still meet Energy Star certification is based on size and resolution. Specifics for allowed consumption amounts for different TVs in on mode can be found on page 5 of Energy Star's Requirements document.
