Energy vs Climate: How climate is changing our energy systems

The aftershocks of the Iran war are reshaping energy markets, investment decisions, and climate politics in very different ways around the world.

David, Sara, and Ed sat down with Vijay Vitheeswaran, Global Energy and Climate Innovation Editor at The Economist and 2025 Energy Writer of the Year, to discuss the shock rippling through energy markets since the war in Iran began. 

On one side are forces accelerating the energy transition like electrification, EV adoption, solar deployment, and rapidly scaling clean tech. On the other are forces pushing toward deeper fossil fuel lock in: energy security fears, coal expansion, oil investment surges, and persistent fossil fuel subsidies. Which force is actually winning?

The conversation covered a lot of ground — from samosa vendors in Delhi packing up because cooking fuel tripled in price, to what a potential OPEC collapse could mean for the oil sands.

This show's a great listen, especially if you're trying to make sense of a world where the energy transition and fossil fuel lock-in are happening simultaneously.

Nuclear is having a global moment. But the story in Canada is a lot more complicated.

David, Sara, and Ed sat down with Prof. Jason Donev of the University of Calgary for a full, unsparing look at where nuclear fits in a rapidly growing and electrifying Canadian grid.
Jason is one of the clearest thinkers on energy systems in the country. He's also someone who started out opposed to nuclear and changed his mind. 
We set this episode up to tackle two questions. First, what is the case for new nuclear right now, given rising electricity demand from electrification, industry, and AI. And second, why Canada, despite decades of experience, has struggled to build new projects beyond Ontario and New Brunswick.
A few things you'll hear about:
Canada had a nuclear accident in 1952. Jimmy Carter helped clean it up.
“Small” modular reactors can be up to 300 megawatts. A CANDU is closer to 700. “Small” is a relative term.
Darlington’s BWRX-300 is a closely watched test case for Western SMRs. Will costs fall with follow-on units, or will nuclear repeat its Achilles heel and get more expensive?
It turned into a lively and wide-ranging conversation on costs, timelines, small modular reactors, and the deeper issue that keeps coming up with nuclear. The physics may be solved, but the politics and institutions are not.

About Our Guest:
Prof. Jason Donev is a tenured professor teaching Energy Science and Physics at the University of Calgary. He leads EnergyEducation.ca, the world’s largest and most widely used energy resource for adults.

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.

About Our Guest Host:
Rob Tremblay is Policy Manager at Energy Storage Canada, where he leads policy analysis and advocacy efforts across Alberta while contributing to federal and technical policy initiatives nationally. He also Co-Chairs the Board of the Calgary Climate Hub. He's passionate about advancing the energy transition and is a frequent Energy vs Climate listener and questioner.

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.
