The White House is going green. Solar panels are being installed on parts of the residence, making good on a pledge that dates back to 2010.
"The install is part of an energy retrofit that will improve the overall energy efficiency of the building," the official said.
"The project will help demonstrate that historic buildings can incorporate solar energy and energy efficiency upgrades," the official said.
Since taking office in 2009, Obama has made green energy a priority for his administration. He has since used his executive powers to bring in tougher vehicle fuel efficiency standards. In June, he unveiled a new proposal to combat climate change.
