from the living-off-the-grid dept.

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?

    A total continent-wide loss of electricity due to geomagnetic storm hopefully won't be a regular event.

    The point is not the loss but the ability to recover. You don't think stuff will work again, just like that, after the event do you? After the event where are you going to get your next watt from when all the generators are burnt out and you have lost the capability to build more. How do you rebuild with no manufacturing capacity remaining?

      My post was about the claim that the planes already in the air would not be able to land.

        Was not my claim. I claim there wouldn't be a functioning system left. I am not sure of the percentage of fly-by-wire aircraft but those would just be totalled. I am pretty sure almost any aircraft except some Chinese and Russian military aircraft would drop out of the sky. Aircraft without much electronics would still work.
