The New York Times revisits the historical electrical blackout across the U.S. and Canada in 2003. A lot of work has been done to improve our power grid, but are we really safe from another national power outage?
2003 saw one of the largest blackouts in history. It hit cities as far away as Cleveland and New York City. 50 million people were without power. This presented major issues like the number of people who were trapped in elevators and on subways, but it also brought to attention the weaknesses in the national power grid. After much investigation, it was discovered that the blackout had been caused by a downed power line in Ohio. Because there is no centralized system, human and computer error led to the blackout. Improvements have been made to the system, but trillions of dollars would need to be spent to get the power system to where it really should be.
