You should read "One Second After" by William R. Forstchen. This is a very good read about the aftermath of our electrical grid going down. It's a story about people surviving, not a technical discussion of things.

There is a sequel titled "One Year After" that came out recently. Well, the paperback version was released "recently", the hardback has been out a little longer. I picked that one up on the day it was released in paperback, but I haven't started reading it yet.
