China, Clean Energy and the Future of U.S. Energy Security with Harry Krejsa

Cyber Focus

In this episode of Cyber Focus, host Frank Cilluffo sits down with Harry Krejsa, Director of Studies at Carnegie Mellon University's Institute for Strategy and Technology. Krejsa, a former Pentagon and White House cyber strategist, discusses his latest report, Sunshield, which highlights the intersection of cybersecurity, U.S.-China competition, and grid security. The conversation explores how China's cyber operations exploit technical debt in U.S. critical infrastructure, the cybersecurity risks and opportunities in the energy transition, and how the rapid buildout of AI-driven power demand presents both new challenges and unique opportunities. Krejsa outlines strategic actions the U.S. must take to secure its energy future and broader critical infrastructure against Chinese cyber threats.
