  • Self congratulating capitalist tripe

    If you want to hear a bunch of privileged capitalists get together and tell each other how great they are at saving the world and being eco warriors then this is for you. It’s pathetic, flimsy and superficial. The only episode I listened to was a tour around the inside of Europe’s largest data centre. It’s sickening how much money is being poured into protecting chips when there is so much human tragedy in the world. Vulnerable women, children and babies the world over are dealing with war, fami... more

  • Great podcast series from an OG!

    Liebreich has been involved with renewable energy for many years, starting Bloomberg New Energy Finance (BNEF) years ago and his experience shows. Many of these episodes include captivating discussions and clarity around current issues in renewables. Liebreich isn’t shy on providing his well researched opinion and rationale behind it.

Talking Points

Recent interactions between the hosts and their guests.

Why Flexible Power Is Suddenly So Valuable | Ep259: Håkan Agnevall
Q: What is driving Wärtsilä's growth in data centers?
The rapid growth of AI-enabled data centers, especially in the US, is creating demand for large, reliable, modular power solutions that can be deployed off-grid or grid-tied with fast ramping and high uptime.
RCP8.5 Is Dead, What Comes Next? Ep260: Roger Pielke, Jr.
Q: What happened with RCP 8.5 and why is it considered implausible now?
The guest explains that RCP 8.5 was never a plausible representation of the future; it came to dominate discourse due to early framing, media coverage, and the way scenarios were adopted by policy and IPCC processes. New analyses show much lower chances of a future powered by coal and extreme emissions, and the high end of that pathway is not supported when plausibility and changing demographics are properly accounted for.
India’s Solar Revolution Is Bringing Cheap Energy To Millions | Ep257: Harish Hande
Q: Why do you emphasize decentralized energy as a pathway to livelihoods rather than expanding centralized grid power?
Because distributed energy aligns energy access with actual on-the-ground needs, reduces transmission losses, and enables specific use-cases (health centers, dairy processing, education) that directly improve livelihoods and outcomes; it also offers modular, bankable opportunities that scale through existing financial products.
Europe Needs Clean Tech More Than Ever | Ep 255: Thomas Pellerin-Carlin
Q: Thomas, can you summarize how energy policy actually gets made in Europe today?
Europe relies on a mix of regulations, directives, investment instruments, and enabling tools, with a push for predictability and gradual implementation across member states to coordinate a continent-wide transition.
⁠Energy Shocks, Inflation & Risk: How a Central Bank Responds to Crisis | Ep252: Pierre Wunsch
Q: How do you view the role of carbon pricing given practical concerns about credibility and long-term investment?
The guest argues for a credible, clear carbon price trajectory complemented by subsidies and R&D to address the expensive, long-horizon technologies, noting that markets discount uncertain long-run prices and that policy design must consider political feasibility and instrument credibility.
