As momentum gathers for the creation of an Internet-like "smart grid" that will do for the electricity grid what the Internet did for home shopping, the WSJ reports the cyberspace wars have begun. The big question is whether the move to a smart grid would increase the country's vulnerability to cyber attacks, or serve as the best form of defense. California-based Electric Power Research Institute has been selected by the Commerce Department to draw up the "roadmap" of the new smart grid. Its main task will be figuring out just what standards should prevail in that brave new world.
