A revamped set of Energy Star requirements went into effect last week, much to the chagrin of plus-sized plasma TVs everywhere. Under the new specification (Version 5.3), sets bearing that vaunted blue sticker will have to be, on average, about 40 percent more energy efficient than standard models, while larger displays will be held to even stricter requirements. The latest iteration also calls for qualifying TVs to adhere to a "hard cap" of 108 watts (irrespective of size), essentially disqualifying any plasmas at least 50-inches in size, and any larger, non-LED-backlit LCDs. Among those sets that qualified for certification under Version 4.2, a full 14 percent consume more than 108 watts (mostly 2010 models), and only three are LED LCD-based (including Samsung's UN65D8000). Some newly disqualified 2011 models, however, may still bear blue stickers, due to Energy Star's ongoing transition process. "With the intention of seeing products that meet the newest requirements on retail shelves when 5.3 takes effect, EPA halted certification of new TVs that met the 4.2 requirements (but not the 5.3 requirements) as of May 31, 2011," Energy Star product manager Katherine Kaplan explained to CNET. "All new products certified since May 31 meet the 5.3 requirements. A product newly manufactured and certified in June had to meet the 5.3 requirements to be labeled."
