Best Energy Choices in TV Technologies

As the mid-February deadline looms for conversion of U.S. television broadcasts to digital signals, millions of people will take advantage of the government coupon program for buying an Energy Star digital-to-analog converter for their existing set (dtv2009.gov). But others will see the switch as a signal to purchase a new TV, making it time to recycle the older set. In addition to screen size, resolution and auxiliary connections, it’s also time to consider energy use.

 The Union of Concerned Scientists, at ucsusa.org/publications/greentips, spells out the best options. First look for an Energy-Star rated model. Then choose a rear-projection microdisplay mode (commonly known as DLP, or digital light processing). According to a study by technology reviewer CNET, a DLP consumes only .13 watt per square inch of screen. LDC TVs use more than twice that, at .28 watt per inch, with plasma TVs dead last at .33 watt per inch.


Other energy-saver tips: Turn off the quick start option to cut standby power consumption. Turn down brightness settings. Unplug the TV when not in use.
