A new study by the U.S. Environmental Protection Agency has revealed America's most energy efficient cities based on buildings and several major cities made the cut.
The second annual EPA ratings were calculated based on how many commercial buildings in each city were designated "Energy Star Leaders."
Energy Star Leader buildings are structures that reduce energy use by 10 percent and perform "in the top 25 percent of similar buildings nationwide," the EPA said in a press release.
"These cities see the importance of taking action on climate change," said Gina McCarthy, assistant administrator for EPA's Office of Air and Radiation, noting that they are reducing greenhouse gases and cutting energy bills.
The Top 15 cities on the list are shown below, along with the number of Energy Star buildings in each and the amount of money it's saved due to energy conservation. Rank each on whether or not it surprises you.
