I've actually worried about this one a lot after reading about the solar storm of 1859. For those of you who haven't read about it (http://en.wikipedia.org/wiki/Solar_storm_of_1859 http://en.wikipedia.org/wiki/Solar_storm_of_1859) I highly recommend reading up on it. The TL;DR version is that one of the largest solar flares ever recorded was produced on the surface of the sun and the ensuing geomagnetic storm that passed by earth was so strong it was able to power telegraph machines that were not plugged in. My laymen speculation is that this would be much worse than just transformers, given how computers are penetrating every aspect of our lives. Imagine the impact to our society if transportation and electricity failed simultaneously.
