Energy vs Climate: How climate is changing our energy systems

EvC Superfan and fellow energy nerd Robert Tremblay turns the tables on Sara and Ed — asking the questions the podcast usually doesn't: how EvC started, the energy transition over the 7 seasons of the show, what's changed, and whether any of it is working.

They get into their backgrounds, the EvC origin story (are the rumours about Danielle Smith true?), how the show has evolved, and what they actually think about Canada's climate trajectory. Plus a rapid-fire round... well, at least as rapid-fire as EvC gets.

Energy vs Climate X Climate Books Reviews 
This week we're sharing an episode from Ed's other podcast, Climate Book Reviews, co-hosted with Dr. Roger Thompson of Arizona State University. 

Their guest is John Vaillant, author of Fire Weather: The Making of a Beast. (US and International - Fire Weather: A True Story from a Hotter World)

Many listeners will know Vaillant from his earlier books The Golden Spruce and The Tiger, both gripping works of narrative nonfiction. In Fire Weather, he turns his attention to the massive 2016 Fort McMurray wildfire and what it tells us about the new era of extreme fire.

In this episode:
How the Fort McMurray fire burned for a week straight — and why traditional firefighting was useless
The concept of "fire weather" and why wildfires are now generating their own atmospheric systems
The oil industry's early awareness of climate change and the shift to deliberate misinformation
Attribution science: can we prove a specific wildfire was caused by climate change?
What hope looks like in the face of an altered climate

The Iran war and the near-closure of the Strait of Hormuz have triggered a major shock to global oil and LNG markets. 
Roughly 20 million barrels of oil per day normally move through Hormuz. The IEA says nearly all of that has been disrupted.

Oil and gas prices have surged sharply; and the disruption extends well beyond oil as Qatari LNG exports have been largely severed. Asia is especially exposed, since most Gulf energy exports flow there. 
This isn’t just an oil story. It’s a “can people cook dinner” story, a reminder that geopolitics gets real once it enters the kitchen.

In this episode, David, Sara, and Ed unpack what this shock means for global energy markets, the climate, and the pace of the energy transition.

Vijay Gadepally joins Ed and Sara to break down the real energy footprint of AI—and why most people (and companies) are getting it wrong. 
They discuss: 
How "agentic" AI systems use an order of magnitude more energy than ChatGPT.
Whether efficiency gains can keep pace with exploding usage (spoiler: not yet). 
The one simple change that could cut AI energy use by 80%. 
Vijay is Senior Scientist at the MIT Lincoln Laboratory Supercomputing Center and Co-Founder of Bay Compute and Radium Cloud. He studies what's actually happening under the hood of AI systems—and has the data to back it up. If you've been wondering whether AI is derailing the clean energy transition, or whether smarter software design could keep energy use in check, this is the conversation you need to hear.

This episode is different. We're tackling China's energy transition, and instead of David, Sara, and Ed just talking about it, they went out and interviewed different experts on the subject.

Why China? Because it's arguably the most important energy story on the planet right now. China is the world's largest emitter. It's also the world's largest investor in clean energy. It manufactures the lion's share of solar panels, batteries, and now electric vehicles in the world.

Functionally, what happens there determines whether the world has any real shot at meeting long-term climate targets. 

David spoke with Andrew Light, distinguished professor at George Mason University and former Senior Climate Official in the Biden administration.

Sara talked with Jeremy Wallace, professor of China Studies at John Hopkins and Christina Pan, a PhD candidate at Cornell researching renewable energy in China. 

And Ed interviewed Hong Li, a professor at the Institute of Physics at the Chinese Academy of Sciences, and an expert on battery chemistry.

Three different perspectives followed by David, Sara, and Ed trying to make sense of it all.
