  • Simple explanations to help understand the complexity of energy

    I recently became re-energized about working in the energy industry. This podcast has been incredible in getting me up to speed with the latest developments.

    Thank you for the simple explanations and the ability to understand in depth the complex politics and how they are shaping energy markets today.

  • Something’s Changing

    About 5 years ago, I remember living with a conservation mindset. Don’t forget to turn the lights off. Monitor you home’s electricity usage (and read those letters from PG&E telling you your performance relative to your neighbors!) And then something changed. Maybe it was buying an EV, or installing solar on our roof. But this mindset of “don’t use the precious electricity!” is disappearing . Sure, data centers have ripped open the reality of how much electricity we need, but maybe they came abo... more

Talking Points

Recent interactions between the hosts and their guests.

Building a big, abundant, clean grid
Q: But I don't have editors or bosses anymore, so I want to start at the top, at the 30,000 foot level, and just tell me, describe for us your thesis.
Jane emphasizes that the central objective is to rapidly build out a clean electricity system capable of powering growing demand, and she argues for a nuanced, multi- dimensional approach that blends technology, policy, and governance. She rejects relying on a single path or solely price signals and instead advocates for an industrial policy mindset that can mobilize investment, create technologies at scale, and build policy coalitions across sectors and regions.
Is there way more conventional geothermal than we thought?
Q: How do you test the accuracy of your model predictions in the field?
We test by comparing predicted temperatures and permeability against actual drilling outcomes, and by flow tests where we can measure heat content and flow rate to evaluate how well the well performs relative to model expectations.
Is there way more conventional geothermal than we thought?
Q: When you're looking for geothermal resources, what are the two main ingredients you need?
The two key ingredients are exceptionally hot rocks and open permeability pathways for fluids to flow; these factors exist in the Western U.S. and Iceland, and you look for places where hot rock and large open pathways align to create convection cells.
Making data centers flexible so they can serve the grid rather than stress it out
Q: How does Emerald Conductor handle the risk of scaling to multi-megawatt or higher events?
Emerald uses virtualization and abstraction to present any data center as a battery-like asset, builds buffers for faults, and deploys AI agents to manage real-time decisions; it has demonstrated multi-megawatt deployments and ongoing collaboration with partners for commercial-scale use.
Making data centers flexible so they can serve the grid rather than stress it out
Q: What is the core value proposition for existing data centers that don't plan to upgrade their compute immediately?
Even existing data centers can gain access to larger and faster power connections by being flexible grid participants and can be paid for flexibility in certain markets, though this is less lucrative than direct power connections.
