The Gist
The authors argue that America's power grid is dangerously vulnerable to attacks from China, Russia, and Iran because we've built foreign-made components (especially Chinese inverters) into our systems and haven't hardened against cyber, physical, or electromagnetic attacks. They call for four urgent fixes: banning adversary-made grid components, prioritizing energy security over other concerns, hardening against cyberattacks, and building EMP defenses.
Conclusion
The U.S. must urgently take four specific actions to harden its power grid against attacks by adversaries like China, Russia, and Iran: banning adversary-manufactured critical infrastructure components, prioritizing secure/reliable electricity in fuel choices, hardening systems against cyberattacks and sabotage, and developing defenses against electromagnetic attacks.
Premises
- Iran, China, and Russia explicitly include attacks on American and allied energy infrastructure in their military doctrines.
- Iran has already conducted cyberattacks on U.S. water supply systems in at least seven states, demonstrating willingness and capability to target critical infrastructure.
- China is the largest producer of electricity inverters used in the U.S. grid, and by remotely controlling these components Beijing could trigger widespread blackouts.
- Chinese military doctrine calls for attacking U.S. domestic energy infrastructure before invading Taiwan.
- Recent real-world incidents (Colonial Pipeline cyberattack, sniper attacks on transformers in California, Utah, and Oregon) show the grid has already been targeted with insufficient response.
- The U.S. military and society are deeply dependent on electricity for communications, logistics, weapons systems, and troop morale, making disruption strategically devastating.
- European and UK net-zero policies and Taiwan's nuclear plant closures have already compromised energy security and, by extension, physical/military security in those regions.
Assumptions
- Adversary nations would actually follow through on doctrinal threats to attack energy infrastructure in a real conflict scenario.
- Removing Chinese-made components and hardening infrastructure would meaningfully reduce vulnerability rather than adversaries finding alternative attack vectors.
- The economic and logistical costs of replacing infrastructure components are justified by the security benefits.
- Renewable energy sources are inherently less stable/secure than traditional or nuclear sources, and this trade-off outweighs other considerations (climate, cost).
- Government and utility companies can effectively implement these security measures without significant market or diplomatic complications.
- The examples cited (Colonial Pipeline, transformer sniper attacks) are representative of a broader adversary-driven pattern rather than isolated criminal/domestic incidents.
