Seeking smart answers to grid questions

The smart grid is positioned as holding the answers to a lot of problems inherent in the complex and unwieldy beast that is the nation's electric grid.

The answers the smart grid provides present a compelling opportunity, but the movement brings up a lot of new questions too - especially for the telecom service providers looking for a piece of the action. Before telcos can define their role in smart grids, they must first define what exactly a smart grid is. And, like most technologies, ask 10 people and expect 10 different answers.
