WASHINGTON (U.S. EPA) – Houston and Dallas top the list of 20 U.S. markets with the most Energy Star homes, according to an announcement released today by the U.S. Environmental Protection Agency (EPA).

San Antonio and Austin also made the list.

The EPA also announced that it reached a milestone for the Energy Star program by passing the one millionth Energy Star–qualified–home mark.

According to the EPA, families living in Energy Star–qualified homes will save more than $270 million on their utility bills this year while avoiding greenhouse gas emissions equivalent to those from about 370,000 vehicles.
