“If we’re in a contingency, shipping energy over the ocean in a contested environment... then we need to think about what kinds of energy technologies are available that are resilient to blockade,” @harrykrejsa.bsky.social tells The Wire China. Read more www.thewirechina.com/2025/09/28/t...

Taiwan’s Achilles’ Heel - The Wire China

Taiwan is almost entirely dependent on imported fossil fuels for its energy supply — a critical weakness in the event of a Chinese blockade.

Batteries are increasingly linking the defense & modern energy sectors. If “tree huggers” and “dragon slayers” join forces, America can reindustrialize on stronger footing. Sarah Hipel & I make the case today in our @washingtonpost.com op-ed. wapo.st/4mvNjen

Opinion | How tree huggers and dragon slayers could recharge a vital industry

The hurdles to marrying clean tech and the defense industrial base are cultural more than technical.

I was thrilled to be back in Taiwan speaking at DSET's National Strategic Summit on Supply Chain Resilience. I appreciated the opportunity to discuss shared US-Taiwan interests in energy and tech security as the AI race heats up.

AI's energy demands are making our grid an even more tempting target for cyberattacks. Mark Montgomery and I argue in our new op-ed that clean tech & advanced transmission can make our grid more defensible & resilient to these attacks while fueling our race for AI advantage.

I thoroughly enjoyed having this conversation on the Columbia Energy Exchange about how clean energy technologies can not only decarbonize our infrastructure, but also fortify it against the kinds of attacks we know Beijing and others are preparing. www.energypolicy.columbia.edu/the-cybersec...
