Jack Killeen

Hello and welcome. I’m Jack Killeen, a curious, driven, and slightly energy-obsessed student currently splitting time between an MBA at UNC Kenan-Flagler and a Master of Environmental Management at Duke University (Energy & Environment, with a secondary focus on Environmental Analytics & Modeling). I started all this with a BA in Economics from Villanova, which gave me a foundation in markets and policy that’s followed me ever since.

I’ve worked at the intersection of clean energy, sustainability, and finance, first at Bessemer Trust, where I helped raise over $1 billion in new assets, much of it in hedge funds and private equity. From there, I pivoted to the world of climate innovation, joining InventWood to work on international expansion, market strategy, and financial modeling. I then interned with Blueridge Climate Ventures, digging into early-stage climate tech deals, performing due diligence, and helping scout what’s next. 

 Right now I’m on the supply chain team at Commonwealth Fusion Systems, working on planning and sourcing for the company’s first commercial fusion systems. It’s pulled me deeper into fusion economics, power markets, and the real-world work behind building a first-of-a-kind reactor. Fusion has become one of my favorite parts of the energy world, and getting to sit inside CFS while it happens has been pretty special. 

Outside of work and school, I recently ran my fourth marathon (NYC!) to raise money for the Leukemia & Lymphoma Society, a cause I care deeply about. I also enjoy hiking, running, camping, and spending as much time outside as possible. Nature has a funny way of keeping you grounded when you spend your days thinking about how to decarbonize the grid.

Welcome to my website, where I share my unfiltered thoughts on energy: mostly nuclear, but also renewables, transmission, and whatever else I happen to be thinking about.
