Backbone in a male-dominated industry

After more than 40 years in the energy industry, Katherine Hamilton is retiring. And that means she’s also retiring from the podcast after a decade behind the microphone.

In this farewell episode, Katherine shares insights into a career that spanned one of the most transformative periods in energy history. We’ll reflect on her accidental entry into grid engineering at Dominion Virginia Power in the 1980s, where she learned to design distribution circuits, calculate load, and build early efficiency projects. 

She talks about how those experiences gave her an intuitive grasp of how the grid works — a foundation that shaped her roles at NREL, in federal advocacy, in leading industry associations, and becoming a trusted policy voice in clean energy.

We’re deeply grateful for the clarity and optimism Katherine brought to every conversation. Over the years, she helped listeners make sense of policy upheavals, market shifts, and the messy, unpredictable reality of the energy transition. 

This is a chance for us to say thank you. Katherine was an incredibly effective translator for the clean energy industry, and we’re going to miss her deeply. 

This is our final episode of the year, but we’ll be back in January with fresh episodes.
