TV manufacturers Samsung, LG, and Vizio build their TVs to pass federal energy-use tests while allowing the TVs to consume much more energy when they operate outside of the narrow test parameters, a report from the Natural Resources Defense Council (NRDC) claims.
This week, the environmental group published the results of a study it did with third-party efficiency consulting firm Ecos Research (PDF). The study found that many of the TVs they tested used more than double the amount of energy listed on the yellow EnergyGuide label every time the TV was used under conditions not tested by the Department of Energy’s (DOE) energy-use test.
EnergyGuide labels also help determine whether a TV qualifies for an EnergyStar label, which indicates whether the TV is among the more energy-efficient in its group.
