What is an 'electrical grid attack'?

Erroll Southers (Former Deputy Director of the California Department of Homeland Security) gives expert video advice on: What is an 'electrical grid attack'?; What's the likelihood of an electrical grid attack?; What can I do in the case of an electrical grid attack? and more...

Someone would attack the grid. They would attack the system that would take out power for a large segment of this country, geographically speaking. Which, as you know, I just usually tell people: look around. Everything that's running stops--everything. And most people have no concept of that. They think, "OK. It's my lights. It's my refrigerator." No, it's everything. And it's not for just a minute, meaning your computer, communications.One of the things that we are concerned about, in terms of response, is having the ability to communicate, the ability to have emergency services, hospitals, those entities up and running, even in the event that we have a grid failure. So it's much, much more than just the lights going off.
