Smart Cites is a concept that is not coming but it’s already here. Cities all over the globe and in America are in the process of transforming their urban centers into more efficient, resilient, sustainable and livable spaces for citizens to be able to “Live, Work and Play” in. The Smart Cities Council defines a smart city as one that has digital technology embedded across all city functions. The challenge is not just getting these functions to work in sync but how do we “power” everything? The last 8 years the government promoted a Clean Power Plan as the energy solution to build our smart city frameworks. . Is switching energy sources simple as switching one Lego block for another is it “plug and play”.Can cities just swap out their entire electric power grids to renewable energy? Would that be “smart” to do?
