Energy vs Climate is a live webinar and podcast where energy experts David Keith, Sara Hastings-Simon and Ed Whittingham break down the trade-offs and hard truths of the energy transition. Guests include scientists, policy experts, and industry leaders.
The AI energy conversation is focused on the wrong thing.
Training = ~20% of lifecycle energy use.
Inference = ~80%.
Every query shifts the balance further. MIT's Vijay Gadepally from our latest episode. 🎙️

A single AI server node draws 30–50 kilowatts of power.
That's the equivalent of you plus 10–15 neighbours' daily energy use at the same time.
MIT's Vijay Gadepally on the real energy cost behind every prompt you send. 🎙️
#AIEnergy #ClimateChange #EnergyVsClimate
One AI query = electricity for 10-15 homes.
MIT's Vijay Gadepally on why 80% of AI energy now comes from using it (not training), how agentic AI uses 10x more power, and why one vacation planning request consumed 500,000 tokens.

18.64 million EV chargers in China versus 35,000 across Canada.
Christina Pan walks through exactly how China built that — and why the model looks nothing like what we have here.

China's energy transition isn't a story about ideology or green identity.
It's institutional — set direction, tolerate failure, scale ruthlessly when something works.

Very interesting convo on aviation and what can, and can't, be done to lower its emissions.

Andrew Light recounting a conversation at COP with a senior Chinese nuclear official.
China looked at the global pledge to triple nuclear by 2050 and decided it was too small a target to bother signing onto.

@jeremywallace.bsky.social argues that China's EV success is less about state control than about brutal startup competition. Capitalism working the way it's supposed to.

This was a fun episode, each of us talked to different folks (thanks @jeremywallace.bsky.social and Christina (who is not on bsky?) both inside and outside of China and then we got together for a quick chat about what we heard.
(and yes it was a logistical nightmare for @amitinoz.bsky.social)
New episode of Energy vs Climate — and it's a different format.
David, Sara, and Ed each interviewed experts separately. Then debriefed together.
Four guests. A lot of assumptions challenged.

"If there is all this money coming out—dividends, buybacks—and it continues to be a cash cow, why should public money go into this business?"

I enjoyed listening to this conversation on my bike commute this morning, and was very happy that @shastingssimon.bsky.social you corrected the take on the IEA 'backtracking' on peak oil... and seeing today's news illustrates that this is an important difference.

Oilsands reality check:
Operating costs: $20-30/barrel ✅
New project needs: $70/barrel
WTI forecast: $50/barrel 📉
EV market share: 25% & rising 📈
New investments? Math doesn't work.

Alberta claims energy transition leadership while:
- Producing ~1 barrel/day per person
"Would you expect the French to lead a transition away from wine?"

New episode: We recorded live in Calgary tackling Alberta's energy transition.
Oil sands economics. Who pays for decarbonization. What Alberta bets on next. Plus, great audience Q&A.
Honest conversation Alberta needs.

Climate travel tip: Fly in the morning, not at night ☀️
Contrails trap heat 24/7. But during the day, they also reflect sunlight (cooling). At night, it's all warming, no cooling.
Summer morning flights = best. Winter night flights = worst.

Could we cut aviation's climate impact 50% overnight?
Just fly higher/lower to avoid ice-supersaturated zones where contrails form.
Trade: 5% more fuel
Benefit: 90% fewer contrails
Sebastian Eastham explains.

Climate cosplay: when it LOOKS like climate action but isn't.
Example: "sustainable" aviation fuel that's dirtier than fossil fuel.
"Like turning champagne into tap water and paying extra."

Thanks to everyone who made it out to our live show last night at Avatar Innovations!
We had a great discussion on Alberta's Energy Transition & Economic Diversification and a fantastic Q&A to wrap things up.
Was great to meet so many listeners in person! See you again next time!
"You can't burn batteries. You have to carry dead batteries with you for half your trip."
Sebastian Eastham (@imperialcollegeldn.bsky.social) breaks down the battery problem for electric planes.

Some solutions exist today and don't require waiting for new tech. So why aren't we using them?
It's a lively and at times blunt conversation, with sharp audience questions and limited patience for climate cosplay. You'll get the cosplay bit once you listen...
Can we actually decarbonize aviation? Or is sustainable flight decades away?
Sebastian Eastham (@imperialcollegeldn.bsky.social) breaks down aviation's climate impact—and possible solutions.

"Why do we need incentives for carbon removal?"
Short answer: The market won't do this on its own. Ed Whittingham explains the policy & economic realities behind scaling CDR.
