I saw this show on TLC, or the Science Channel a couple of months back and it was about a worst case scenario on Solar Storms.

Basically, if a large enough Coronal Mass Ejection (CME) were to hit earth, the U.S. power grid would be overwhelmed from the event, and large transformers would be destroyed. If I remember correctly, there are only like 10 manufacturer's in the world, and 6 are located here in the U.S. They need electricity to produce their transformers.

Anyone know the name of this show?

This is probably TEOTWAWKI, but, I want to see if I can find this show again.
