The Energy Transition Show with Chris Nelder

What architectural and construction techniques are best for creating comfortable, healthy, and affordable buildings in Alaska? Part 1 of a miniseries on Alaska.

Nic Fulghum, an energy analyst and lead author of Ember's Global Electricity Review 2025, brings compelling insights on the rapid progress of the energy transition. He reveals that solar is growing faster than any energy source in history, electrification is dramatically reducing fossil fuel demand, and global power-sector emissions may be peaking. With renewables and nuclear now over 40% of the energy mix, Fulghum's data challenges skeptics and highlights the accelerating shift towards clean energy.

Mike Grunwald, a veteran reporter and author of 'We Are Eating the Earth,' dives deep into the truths about bioenergy. He questions whether biofuels like ethanol and biodiesel truly offer carbon-neutral benefits, especially when it comes to land usage and deforestation. Grunwald shares insights from his global research, revealing that many bioenergy solutions have unintended consequences that undermine their environmental claims. The conversation also highlights the political dynamics influencing biofuel policies and challenges the narrative surrounding agricultural practices and climate change.

How can a country replace a critical technology like blast furnaces with a low-carbon alternative while preserving national security and jobs?

How will South Australia maintain stability and reliability as it becomes the world’s first gigawatt-scale grid to operate with a 100% renewable energy supply?

Will Russia finally get on board with the energy transition, or will it just white-knuckle its energy exports all the way down to zero?

Dr. Martin Green, the “father of solar cells,” recounts the evolution of modern solar PV cells, and we interview the CEOs of two CSP companies in Australia.

What will it take to make next-generation geothermal energy economically competitive and commercially available all over the world?

Numerous energy innovations in Australia help to integrate DERs, VPPs, microgrids, advanced solar and grid technologies, efficient buildings, and more.

How is the Australian government is working with the grid power sector to plan and execute its transition away from fossil fuels and toward renewables?
