Power grid down disaster scenarios are not just fodder for movie plots -- they pose a pressing concerns for government and security experts as well. The United States electrical grid fails more than its counterparts in any developed nations, but system problems posed by weather and peak usage are only a fraction of the problems that could spell disaster for millions of Americans.
A power grid analysis compiled by USA Today from government records shows that the nation's power grid is vulnerable and is often subject to attack. As previously reported by the Inquisitr, the United States power grid is comprised of 160,000 miles of transmission lines and 55,000 different sub-stations. Approximately once every four days, the electrical grid is struck by either a physical or a cyber attack. Former Department of Homeland Security Secretary Janet Napolitano said that a cyber attack worthy of taking down the power grid was a matter of "when" not "if."
