The Consumer Electronics Association (CEA) this week released a study which shows how much more energy efficient flat panel televisions are today than six or seven years ago.
The report, produced by research firm TIAX LLC, reviewed power consumption data on best-selling high-definition liquid crystal (LCD) and plasma display models produced between 2003 and 2010. The report examined active and standby power consumption in models with screen sizes ranging from 13- to 65-inches.
Among the groups findings:
- LCD active power use fell 63 percent from 2003 to 2010.
- LCD standby power use dropped 87 percent from 2004 to 2010.
- Plasma TV active power use dropped 41 percent from 2008 to 2010.
- Plasma TV standby use fell 85 percent from 2008 to 2010.
The group says the power consumption of the average TV sold in 2010 consumes less energy than a 100 watt incandescent light bulb and less power than what is needed to light a typical living room.
“Power consumption in TVs has fallen dramatically." said Douglas Johnson, vice president of technology policy at CEA, “Many consumers don’t realize they can replace an old analog TV with a new flat-panel digital TV that uses less energy.”
Gains in LCD Televisions were primarily attributable to the shift towards LED backlighting while plasma display panels saw significant improvements in energy efficiency thanks to the optimization of the xenon/neon gas mixture, which produces UV light.
In terms of market share, CEA expects LCD TVs to account for 82 percent of TV display sales in 2011 with 27.1 million units shipped. CEA expects 4.6 million plasma TVs to ship this year.
