ENERGY STAR does not label clothes dryers because most dryers use similar amounts of energy, which means there is little difference in the energy use between models.
The Department of Energy's Appliance Standards program conducted a detailed study which found that the clothes dryers on the U.S. market do not vary significantly from each other in terms of energy consumption. This is also the reason why the Federal Trade Commission (FTC) does not require clothes dryers to have a yellow EnergyGuide label.
Over the next few years, DOE Appliance Standards program will be revisiting this study as it determines whether to revise the current federal energy conservation standards for dryers. We will keep a close eye on this process to see if changes in technology and market conditions have made an ENERGY STAR clothes dryers program more feasible.
