Environmental Defense Action Fund, United Steelworkers, and the Blue Green Alliance unveiled new television ads this week in support of a cap on carbon and a comprehensive green energy and jobs bill.

The housing collapse be damned, Kitson & Partners announces it will build a planned city near Fort Meyers with 19,500 homes, offices, retail shops, and light industry. Its electricity will come from the world’s largest solar voltaic power plant, a $300 million, 75-megawatt plant to be built on-site by Florida Power & Light. That’s nearly twice as large as the current largest plant in Germany, says Time magazine.

The planned city—Babcock Ranch—will include a smart grid to let residents monitor and adjust their energy consumptions. More than half of its 17,000 acres will be permanently protected as greenways and open space, according to the Miami Herald.
