Boston Mayor Thomas M. Menino has been pushing real estate developers and property owners to make their buildings more energy efficient and environmentally friendly. Now he’s going green at home, too: Menino is installing solar panels on the roof of his home to help promote a state program that makes it cheaper for residents to go solar.

“If I’m the mayor of Boston, I should be participating also,” Menino said. “We’re making sure we’re leading by example.”
