On Sunday, October 27th the National Geographic Channel will be presenting a "world premiere movie event" called American Blackout. It looks like it is scheduled for 9 PM Eastern and Pacific -- please check your local listings.
This is a video made on the premise that the US electric grid would be knocked out due to a cyber attack.
I have not seen the video --- only the trailer which you can find at this link.
If you look closely on the video there is a link http://www.survivetheblackout.com/1/ that takes you to a graphic depicting the 10 days of the blackout along with some ideas described as "Personalize your Experience" to help you through such events. A screen shot of "Day 1" is below. This information does appear to be helpful and less dramatic than posed in the video.
I plan on watching the show, but the trailer concerns me that there will be more "drama" than fact. If NOVA were to be offering this video I'd be more confident in the factual content and demeanor.
Anyway, decide for yourself but please remember that the North American electric grid (map below) is made up of large, separate geographic sections and that knocking out the entire US grid is highly unlikely -- even from a physical or cyber attack.
I look forward to your thoughts on this video.
