On March 13th, 1989 a surge of energy from the sun, from a "coronal mass ejection", had a startling impact on Canada. Within 92 seconds, the resulting geomagnetic storm took down Quebec's electricity grid for nine hours. It could have been worse. On July 23rd 2012 particles from a much larger solar ejection blew across the orbital path of Earth, missing it by days. Had it hit America, the resulting geomagnetic storm would have destroyed perhaps a quarter of high-voltage transformers, according to Storm Analysis Consultants in Duluth, Minnesota. Future geomagnetic storms are inevitable.

And that is not the only threat to the grid. A transformer-wrecking electromagnetic pulse (EMP) would be produced by a nuclear bomb, designed to maximise its yield of gamma rays, if detonated high up, be it tethered to a big cluster of weather balloons or carried on a satellite or missile.

[...] After the surge, telecom switches and internet routers are dead. Air-traffic control is down. Within a day, some shoppers in supermarkets turn to looting (many, unable to use credit and debit cards, cannot pay even if they wanted to). After two days, market shelves are bare. On the third day, backup diesel generators begin to sputter out. Though fuel cannot be pumped, siphoning from vehicles, authorised by martial law, keeps most prisons, police stations and hospitals running for another week.

[...] Yet not much is being done. Barack Obama ordered EMP protection for White House systems, but FERC, the utilities regulator, has not required EMP-proofing. Nor has the Department of Homeland Security (DHS) pushed for a solution or even included EMP in official planning scenarios. (The Pentagon should handle that, DHS officials say; the Pentagon notes that civilian infrastructure is the DHS's responsibility.) As for exactly what safeguards are or are not needed, the utilities themselves are best equipped to decide, says Brandon Wales, the DHS's head of infrastructure analysis.

But the utilities' industry group, the North American Electric Reliability Corporation (NERC), argues that, because EMP is a matter of national security, it is the government's job. NERC may anyway be in no rush. It took a decade to devise a vegetation-management plan after, in 2003, an Ohio power line sagged into branches and cut power to 50m north-easterners at a cost of roughly $6bn. NERC has repeatedly and successfully lobbied Congress to prevent legislation that would require EMP-proofing. That is something America, and the world, could one day regret.

Is a widespread blackout the end of the world?

    I experienced the 2003 blackout in New York City. A giant triangle of outage covered the Northeast. It was summer. It took them days to restore power. Millions of people had to walk home at once. There were no riots or looting. People didn't panic. They handled it. Ice cream shops gave their ice cream away. People checked on their elderly neighbors. Everyone helped out strangers.

    So it was possible for people to enjoy the unexpected benefits of having no electricity. BBQs on the roof and being able to see the Milky Way over Manhattan.

    Life, even modern life, can continue without electricity if it has to.

    That is encouraging to hear. I suspect that there was a universal expectation that the power would be restored in a short time. That the power loss condition was not permanent, or at least not long term (eg, months)
