plasma TV that bathed you in warmth all winter will soon become between you, your air conditioner and comfort. Yes, we love the images that are pumped out by the emissive cells of a plasma display, but as a general rule, LCDs spin the electric meter more slowly. This benefit is not lost on The LCD TV Association, which has launched its GreenTV logo program to tout the fact. The baseline requirement for an LCD TV to wear the badge is ambient light sensors that adjust the backlight brightness, a feature good for at least a 30-percent reduction in electricity consumption. The association has more plans as well, so expect to see environmentally-conscious features like recyclable parts, fewer heavy metals, and LED backlights get billing as well. With the EPA's Energy Star ratings coming to TVs this year, being "green" could be a real differentiator in the market -- and we all know that more badges on the box mean more sales, right?
