As of aboriginal 2008, boilerplate refrigerators charge 20% accumulation over the minimum standard. Dishwashers charge at atomic 41% savings. Best accessories as able-bodied as heating and cooling systems accept a chicken EnergyGuide characterization assuming the anniversary amount of operation compared to added models. This characterization is created through the Federal Trade Commission and generally shows if an apparatus is Activity Star.9 While an Activity Star characterization indicates that the apparatus is added activity able than the minimum guidelines, purchasing an Activity Star labeled artefact does not consistently beggarly you are accepting the best activity able advantage available. For example, dehumidifiers that are rated beneath 25 US pints (12 L) per day of baptize abstraction accept an Activity Star appraisement if they accept an activity agency of 1.2 (higher is better), while those rated 25 US pints (12 L) to 35 US pints (17 L) per day accept an Activity Star appraisement for an activity agency of 1.4 or higher. Thus a higher-capacity but non-Energy Star rated dehumidifier may be a added activity able another than an Activity Star rated but lower-capacity model.10 The Activity Star program's accumulation calculator has additionally been criticized for unrealistic assumptions in its archetypal that tend to aggrandize accumulation allowances to the boilerplate consumer.11

Another agency yet to be advised by the EPA and DOE is the all-embracing aftereffect of energy-saving requirements on the backbone and accepted account activity of a mass-market apparatus congenital to a consumer-level amount standard. For example, a refrigerator may be fabricated added able by the use of added insulative agreement and a smaller-capacity compressor application electronics to ascendancy operation and temperature. However, this may appear at the amount of bargain autogenous accumulator (or added exoteric mass) or a bargain account activity due to compressor and/or cyberbanking failures. In particular, cyberbanking controls acclimated on new-generation accessories are accountable to accident from shock, vibration, moisture, or ability spikes on the electrical ambit to which they are attached. Critics accept acicular out that alike if a fresh apparatus is energy-efficient, any chump apparatus that does not accommodate chump satisfaction, or charge be replaced alert as generally as its antecedent contributes to landfill abuse and diffusion of accustomed assets acclimated to assemble its replacement
