When Will Ferrell installed solar panels on his home, he tapped into star power, too; through the BP Solar Neighbors Program, Ferrell’s solar power purchase sponsored the installation of a 48-panel solar system for the St. George Hotel, a permanent residence for the formerly homeless run by the Skid Row Housing Trust.

The St. George’s solar system was unveiled today by actor/director Ed Norton, who helped create the BP Solar Neighbors Program, and Mayor Antonio Villaraigosa. The Solar Neighbors Program donates a solar system to a low income family for each solar system installed by a celebrity. Norton explained the program’s mission:

“Many people perceive environmentally friendly practices as costly and available only to the wealthy. We need to expand our awareness of the many ways environmentally sustainable development and construction can apply to affordable housing. The installation of the BP solar panels on the St.George is a great example of a dynamic solution to our intensifying economic and environmental crisis.”

Norton’s green do-goodiness is in his DNA; he’s on the board of the Enterprise Community Partners, a non-profit co-founded by his grandfather, James Rouse. Enterprise, whose goal is “to see that all low-income people in the United States have the opportunity for fit and affordable housing and to move up and out of poverty into the mainstream of American life,” is a partner in the BP Solar Neighbors Program. How’s that for a shining example of the golden rule?
