In just five seconds, 15 gigawatts of power, around 60% of Spain’s electricity supply, vanished… plunging tens of millions into darkness across Spain and Portugal. Transport halted, hospitals scrambled, internet and commerce collapsed. It was a stark reminder that our energy infrastructure, even in highly developed nations, is still alarmingly fragile.
