Footnotes:

*Non-ENERGY STAR qualified units accounted for less than 1 percent of shipments of front-loading washers in 2008 and 2009. Therefore, the average annual UEC is based on a very small number of shipments.
**Note: Part of the improvement in average annual UEC for dishwashers and electric ranges over the period is due to a change in how UEC is measured (the assumption about frequency of use was revised downward to more accurately reflect household usage patterns) and does not represent an actual improvement in energy efficiency.
