HIGH DEFINITION POWER HOGS
Most people shopping for a high-definition television (HDTV) consider screen size, resolution, and auxiliary connections—but what about energy use? According to the U.S. Environmental Protection Agency (EPA), the more than 275 million TVs in this country consume over 50 billion kilowatt-hours of electricity each year. That’s equivalent to the output of more than 10 coal-fired power plants, according to researchers at the Union of Concerned Scientists.
While display technology has become more efficient over the years—liquid-crystal display (LCD) technology uses less energy per square inch than older cathode-ray tube (CRT) technology—energy use increases with screen size regardless of the technology. Some of today’s HDTVs, as a matter of fact, can consume more electricity in a year than a refrigerator.
Energy consumption varies widely between HDTVs, even between models of similar size. There are ways to ensure your new TV is as efficient as possible:
Even if you’re not in the market for a new TV, there are ways to reduce the energy being consumed by your current TV:
