Results: Do you think the power grid will collapse this year?

A string of attacks on power facilities in Oregon and Washington has caused alarm and highlighted the vulnerabilities of the US electric grid. The attacks in the Pacific north-west are similar to the assault on North Carolina power stations that cut electricity to 40,000 people. It’s unknown who is behind the attacks but experts have long warned of discussion among extremists of disrupting the nation’s power grid. The US electrical grid is vast and sprawling with 450,000 miles of transmission lines, 55,000 substations and 6,400 power plants.-The Guardian
