A massive solar storm emitted from the sun could fry electronics and satellites around the globe, and take down much of the power grid. A 2009 report from the National Academy of Sciences said that such a storm could cause some $2.6 trillion in damage and a full recovery could take years. John Kappenmann, a co-author of the National Academy of Sciences 2009 report, found that a large solar storm could leave 130 million in the dark.
