Rerference the book "48 hours", by William R. Forstchen , how plausible is it that the Earth, at some time in the near future, will be hit by a Coronal Mass Ejection (CME) from the Sun, a "Carrington Event" that has the power to shut down and possibly destroy the world's electrical infrastructure? Is there a timeline on when the next solar flares would be strong enough to do so? If so, when? How best to prepare for such an event, for our own homes as well as our nations infrastructure?
