did Senator Obama ever "go green" at his old Chicago house? Did h ever install any solar panels, paid out of pocket, on this old Chicago home to save on his personal energy bill/consumption. Maybe we could use this house as a example on how he did it, to retro fit and upgrade to "green" on an older building. Does he have those silly tube lights? any solar panels present ? did he insulate the roof and walls ?
