Sen. Bernie Sanders (I-VT), chairman of the Senate's green jobs subcommittee introduced legislation with nine cosponsors to encourage the installation of 10 million solar systems on the rooftops of homes and businesses over the next decade.

Sanders said a recent report shows that solar power could help make every state more energy independent if solar units were installed on available rooftop space, because every state can meet 10 percent or more of its electricity needs just through rooftop solar.
