about GREEN TV
A recent article on the Scientific American website says that some flat screen TVs draw more power than a large refrigerator.
According to The Wall Street Journal’s Rebecca Smith, a 42-inch plasma TV set can draw more power than a large refrigerator, even if the TV is only used a few hours a day. Smith recommends green consumers consider the Liquid Crystal Display (LCD) models, which typically uses less energy than comparable plasma sets.
According to the U.S. Environmental Protection Agency (EPA), a 28-inch conventional cathode-ray tube (CRT) set uses about 100 watts of electricity. A 42-inch LCD set might consume twice that amount, while plasma could use five times as much, depending on the model and the programming. For the largest screen sizes (60 inches and up), projection TVs are the most energy efficient, clocking in at 150-200 watts—significantly less than the energy a plasma set would use.
Of course, the greenest option of all (aside from getting out from in front of that tube and spending more time outdoors) is to keep or repair your existing CRT unit (a digital-to-analog converter will be needed after February 2009 when new signal specifications go into effect). Most CRT sets use less energy than any of the LCD or plasma models, and if it ain’t broke, why fix it? Buying a new TV, even a greener one, only generates more pollution in production and transport, and creates waste in junking the old model.
Luckily for us consumers, beginning in November 2008, TVs will start displaying "Energy Star" labels. So if we're determined to buy an LCD to save floor space, we can identify the greener choices.
