Electrical energy systems operate according to the principle of connected vessels, with the problems in one system quickly spilling over into the next one -- as was the case during the power collapse in the United States and Canada in 2003.
Elektroenergetski sistemi funkcionišu po principu spojenih sudova i problemi u jednom sistemu brzo se prenose na drugi -- kao što je bio slučaj tokom strujnog kolapsa u Sjedinjenim Državama i Kanadi 2003. godine.
