CWmike writes "The US Department of Homeland Security is looking at a report by a research scientist in China that shows how a well-placed attack against a small power subnetwork could trigger a cascading failure of the entire West Coast power grid. Jian-Wei Wang, a network analyst at China's Dalian University of Technology, used publicly available information to model how the West Coast grid and its component subnetworks are connected.
