City 2.0: Using tech building blocks in tomorrow's urban centers

Science fiction writers call it Utopia, the glorious City of the Future. But short of downtown atriums being guarded by invisible walls and flying cars, City 2.0 is not as far off as you may think.

Ubiquitous wireless networks are already available in cities including Baltimore and Minneapolis, corporations such as Thomson Reuters have sustainable data centers that sell power back to the local utility, the smart energy grid is well on its way, and city-provided social networks are common. Indeed, the next steps toward the city of tomorrow are all about integrating these services cohesively, making them widely available across the entire metropolis and managing the services more efficiently.

"The reality is that the city of the future will likely have many aspects of a contained and managed ecosystem," says Rob Enderle, a consumer analyst with Enderle Group based in San Jose, Calif.

While the concept of City 2.0 is monumental, these key technology advancements are already helping pave the road to the next-generation city.

Smart grid
The smart use of energy is one of the most important goals for urban centers today. The smart grid concept centers around the idea of using electricity when it's available cheaply, rather than at peak times when it's more expensive, and allows wind and solar and other renewable sources to be integrated into the energy grid. This requires two-way communication between utility companies and the businesses and individuals who use their power. We're nowhere near a comprehensive smart grid yet, but some cities and energy companies are taking steps in that direction.
