Energy Star Certifies 26% of New Homes in 2011
The efficiency of appliances furnishing those homes varies by product type; according to a review by EIA, nearly all dehumidifiers, dishwashers, and televisions available in 2011 met Energy Star standards, leading to updated specifications for those categories. Energy Star standards are supposed to reflect the efficiency of the top 25% of products in a category; very few water heaters, for example, meet the standards because electric storage tank heaters cannot match the efficiency of hybrid heat-pump water heaters.
