does your TV use too much energy?

by rebecca elisabeth design

Your TV as an appliance?! Today’s consumers are spending a small fortune on their TV sets and therefore display them prominently in their homes. Some large TVs can consume as much energy as a refrigerator.

Generally, LCDs seem to be the best flat screen option using an average of .28 watts per square inch vs. the average .33 watts per square inch Plasmas. I’ll do the math for you, that means the average Plasma use 18% more energy than the average LCD. The energy saving rear projection TVs use only .13 watts per square inch, sacrificing space for efficiency. The range by brand however is great. For example, 52” LCDs range from .19-.28 watts per square inch while 50” Plasmas range from .15-.42 watts per square inch.

But the future of efficient TV is about to change. The EPA has developed a new set of criteria for HDTV that is scheduled to go into effect November 1, 2008 called: Version 3.0 Energy Star TV. New standards will mandate that 50” HDTVs use less than 391 watts. While most 50-52” Plasmas and LCDs already meet this standard, there are a few energy hogs that don’t. The 3 lowest energy consuming units tested by CNET are: the 50″ Plasma Panasonic TH-50PZ850U, the 50” Plasma Panasonic TH-50PZ800U, and the 52” LCD Samsung LN52A650.

  1. Tvs suck up alot of energy even when off and not plugged in. They are even going further with 4.1 and 5.1 TVs. Probably by next year, you won’t be able to buy a non energy star TV.

  2. Interesting. I’m sorry though – Rick, how does a TV suck energy when it’s not plugged in? Am I missing something?
