What better place than the Sunshine State for the world's first solar-powered city? Called Babcock Ranch, the 17,000-acres-large community will have its energy needs supplied by a $300 million, 75 megawatt solar-powered generator. The city will also integrate a Smart Grid for powering electric vehicles.

While construction won't begin until later this year, Floridian city planners have some ambitious numbers for the solar community: 19,500 homes, 20,000 permanent jobs, 6 million square feet of retail/industrial space and 8,000 acres reserved for open space and greenways.

The biggest hurdle, though, may come after construction when it comes time to populate Babcock. It'll be interesting to see what kind of incentives city planners offer — electric vehicles aren't cheap, after all.
