This is the big lesson from Ukraine. The supply chain for drones is the platform, not the specific models you have in inventory. Those will be used up or obselete in weeks or months.

It's also the main security help we could give to Europe, as a secure drone supply base, out of reach of 'the zone of economic denial' from the likes of Russia, but also independent of the US and China.

And that sort of hedgehog is what would protect agaisnt local security pressures, not conscription.

Having a domestic full stack EV industry is a national security imperative. Doesn't have to be all domestic companies, but they have to be *here*. An EV stack has all the components for a high volume drone stack. And that is the root of any 'hedgehog' strategy.

There are economic and environmental reasons to push on the transition, but we need to be really smart about it to not hurt security.

Jesse @ember42.bsky.social · 03/10/2026
Seperate for environmental reasons, but for Canada moc8ng away from fossil fuels does *NOT* help national security overall, and if we don't get the full stack battery, power converter, motor etc stack, it could arguably worsen national security.

That is fully as many donestic built units as total sold. We likley could build plus import enough to cover, but the model mix would still be an issue.
010
Jesse @ember42.bsky.social · 03/10/2026
We currently do not, but only ~10-15 years ago we did. We built a limited number of models, and swaped with the American factories (inc Toyota and Honda, to get the model mix demanded.

The one area that would be a nice kick is to stop buying US made cars and trucks.

Jesse @ember42.bsky.social · 03/10/2026
Also, as a minimal importer of US supplied energy (only locally for local cost of delivery reasons), cleaning up does nothing to decouple from the US. It can be good in it's own right, but would free up more to export south...

That is to get full loads on Aframax tankers (~0.5-0.7 Mbbl). Roberts bank can do VLCCs at ~2Mbbl per ship. Much bigger yet.

I feel vindicated now...

Jesse @ember42.bsky.social · 01/10/2026
Bigger ships = less transits. Esp if they can shift some current Burrard inlet loadings to Roberts bank...

Ibassume if it was a FID, all provincial approvals were already in place, so no take backs from the next gov?

Only if that is more than the inputs embodied in fertlizer, harvesting, labour, etc, etc...

If minimal public money is at risk, seems fine to me if the corperate money wants to take on that risk...

How much public investment is there in phase 2?

Ottawa should make it clear that if AB's staus is made unclear (via the first referendum) it will need to be resolved before *any* binding funding comitments are made, or such comitments are conditional on remaining in the confederation...

Jesse @ember42.bsky.social · 30/09/2026
That is the point I would like to see analysed. Could we do pre-work so that we can quickly (in days) reverse line 9, and start bringing oil imports in via montreal? The oil would be more expensive, but as an inusrance plan it is probably *much* less investment...
010
Jesse @ember42.bsky.social · 30/09/2026
It's not a completely crazy idea to at least evaluate. But on straight economics it will never look attractive, as it's effectively a super exensive way to mildly boost exports to the US (the share currently that transits back). But as long as MI wants to shut it down, it's a risk anyway.
110
Jesse @ember42.bsky.social · 30/09/2026
Leaning into (locally produced) EVs would also mitigate the risk by reducing the shortfall potential...

Jesse @ember42.bsky.social · 30/09/2026
'Northern shield' can only be valued in terms of an inusrance policy. As such the big question is what would the consequnces, and cost impact of line 5 shutdown. Could we do it via reversing the line to QC and rail? Or would it be fuel shortages?

Jesse @ember42.bsky.social · 30/09/2026
Digging into it, it's mostly AB conventional oil that goes to Sarnia. They ship oil sequntially in pieplines, and they don't mix much, so they can ship multiple grades in one line.

Jesse @ember42.bsky.social · 30/09/2026
If we want to do the deep decarb expansion with mostly variable resources, we will have to accept that we will be discarding a quarter to a half of the power generated, and price that in. The 'excess' is a siren song. It's produced when it's not needed, and can't be absorbed economically.
000
Jesse @ember42.bsky.social · 30/09/2026
Use mountain or Midwest to compare to the prairies, NY or NE to compare ON/QC etc. Use the optimizer sweep. to see the shifts as you go to 90 or 95% hourly matching of clean.
100
Jesse @ember42.bsky.social · 30/09/2026
As the power gets to the very deep decarb, the mixture needs to shift to more firm supply, as variable resources are less able to be absorbed without fuel to offset. Here is a great dashboard: dashboardamerican.github.io/clean-dashbo...

To that extent, where there are very good onshore wind and solar (comparable to the C.tax inclusive marginal cost of gas), they are fine to fuel save against gas firm capacity. But long term, once we have the big electrification in place, and we need to finish with the power sector, holds us back.
100
Jesse @ember42.bsky.social · 30/09/2026
To the extent that more decarb on power makes it more expensive, that is the complete backwards of what we want, as that will slow the other stuff. We should be focusing on expanding power, affordably, w/o adding (appreciable) GHG in doing so.
100
Jesse @ember42.bsky.social · 30/09/2026
More to the point, and bigger picture. With 100B, we should not decarb power. Our power is mostly decarb already. It's only ~7% of our total GHG. We should be focusing on electrification of transport, industry, and then heating.
100
Jesse @ember42.bsky.social · 29/09/2026
Use it to get to NOAK of everything we need, while streamining to get build costs to <2X China. 100B is far short of getti g all the way, but that would put us on the right path...

Jesse @ember42.bsky.social · 29/09/2026
I would far rather build generation, in relative proximity to users, that can be modulated through limited storage to cover the vast majority of uses cases, at high utlization.
120
Jesse @ember42.bsky.social · 29/09/2026
I disagree, but for a different day. I think this approach leads to a very high floor on power costs as system costs (storage, TX, etc) are allocated to users. The distance needed for low correlation is huge, and we don't ever get real regional anti-corrleation (which is what we really need).

Jesse @ember42.bsky.social · 29/09/2026
🤷‍♂️ Them we better get the Capex down... Otherwise we are going to be burning gas for the long haul...

Jesse @ember42.bsky.social · 29/09/2026
A budget crunch ends continued efforts at decarb. Slow and steady is much better than dash and crash.

Jesse @ember42.bsky.social · 29/09/2026
It's gonna take as long as it takes... If we don't get good at nukes, we are not getting off gas as our 'beyond hydro' firm power...

Jesse @ember42.bsky.social · 29/09/2026
It's not fine, that way goes bancrupt power systems / gov budgets! If you actually try to do it at scale anyway.

Jesse @ember42.bsky.social · 29/09/2026
High heating demand is the main show! I struggle to see how we get there w/o some form of Distirct heating. I also think this will be the more predominat use of deep geothermal, to provide the main heatvsource to those in heating centric climates.
110
Jesse @ember42.bsky.social · 29/09/2026
I think we have lots of options for diurnal coverage (which will be basically just BESS eventually), but beyond that we have not actually come up with anything other than resevoir hydro, geological gaseous fuel storage, or tanked liquid fuel storage for longer terms that are playsibly economic.
100
Jesse @ember42.bsky.social · 29/09/2026
I don't think there is a real consensus yet. The challenge with long duration storage is unless it can offer *capacity* value, i.e. high availability in the worst case event for it (a long sustained low ouptut period followed by a severe low output period), it's economics are terrible as fuel saver

Jesse @ember42.bsky.social · 29/09/2026
That's with the ITC, they have it at ~240 w/o those...

Jesse @ember42.bsky.social · 29/09/2026
Make that Euros or Pounds and that's more the ballpark. And those are super mature markets.
100
Jesse @ember42.bsky.social · 29/09/2026
Geothermal to the extent they have the resources, enough wind to trade to BC for some firm hydro in a pinch, nukes to cover the rest (with a soupson of PV), and some batteries to cover short duration peaks / load imbalances.
100
Jesse @ember42.bsky.social · 29/09/2026
The problem with 'catching the peaks' to make use of the 'excess' is that the periods of availability are too concentrated, leading to low utlization of anything trying to make use of that 'excess'. We need to cost variable sources based on the usable output, not the total.
110
Jesse @ember42.bsky.social · 29/09/2026
We should not do offshore. Period. FOAK nuclear prices for non-firm power. Onshore can work decently while supporting hydro.
210
Jesse @ember42.bsky.social · 29/09/2026
The duration of luls is inconsitent, but sometimes are long than anything but resevoir hydro or stored fuels can manage, but infrequent enough to crush the economics of any storage more expensive than those.. (Too few cycles per year for the deep parts of it).
130
Jesse @ember42.bsky.social · 29/09/2026
The issue here is that wind tends to have poor allignment with demand. Higest output in mild weather (shoulder seaons like now, and mild winter weather) but tends to underperfom during hot and some extreme cold periods.
230
Jesse @ember42.bsky.social · 29/09/2026
Large resevoir hydro. And once we have augmented/extended large resevoir hydro as much as it practically can absorb, we have about as much wind as we should build. After that we need something else.

Vanadium is too expensive...

Jesse @ember42.bsky.social · 29/09/2026
There is no economically plausible benefit for large scale, fully across county transmission. Integration around the hydro hubs? Yes, but linking those doesn't add much.
