Could the US grid be brought down by Chinese hackers? To find out, I talked with Patrick Miller, who helped write the cybersecurity rules for the bulk power system and became the first person with federal authority to enforce them. We get into what's actually been hacked, why those "rogue devices" in Chinese inverters are less sinister than they sound, and why squirrels still do more damage than hackers.
