PM Carney announces largest clean energy investment in North American history

A major contributing factor to what is being described is the development of superconducting technology. This is includes high temperature superconducting wind turbines, superconducting hydroelectric turbines, and superconducting transmission lines. From reading the outline, it looks like this project will capitalize on these new technologies.

1mo agoHN ↗

Even without these superconducting technologies, it’s shrewd capital investment policy. This decarbonizes the last 20% of Canada’s electrical generation, replaces any demand growth with clean energy instead of fossil fuel, and allows more domestically produced (Alberta) fossil gas to be exported if needed. Importantly, just like China, it enables self sufficiency and potentially eliminating any dependency on the US for energy needs (with optionality to export excess clean energy to northern US states in the future).

Per ElectricityMaps, all of Canada has less than 20GW of fossil generation capacity, as of this comment. China, on average, installs ~1.75x that much wind and solar in a month.

TLDR Capital is the bottleneck slowing global decarbonization.

1mo agoHN ↗

It would be more accurate to say "better investment opportunities bias investment away from the weak returns of allegedly clean energy" capital is not the bottleneck anymore than it has always been the bottleneck. Higher returning things to choose instead are the bottleneck

1mo agoHN ↗

Fossil fuels receive ~$7T in global subsidies per year, per the IMF, even when less cost efficient than renewables. Markets can remain irrational longer than you can stay solvent. It’s government’s job to step in and correct market failures, when appropriate, including mispricing of potential investments.

https://www.imf.org/en/topics/climate-change/energy-subsidie...

(the world has already deployed 3TW of solar, and is approaching 1TW/year deployment rate, so we’re almost to the tipping point where fossil fuel subsidies will no longer be relevant; until then, finger on the scale when needed)

1mo agoHN ↗

not that relevant. The investment opportunity set is not limited to fossil fuels. Also that report includes large price skewsfor essentially manufactured uncaptured environmental costs, part of which is political in mature to justify subsidy of renewables, where their buddies make excess returns from said subsidies. Its not quality research

1mo agoHN ↗

My context comes from sitting in on a meeting put together by BloombergNEF during Climate Week 2026 in London where they specifically discuss the global capital market current state as it relates to renewables investments. I'll see if I can find a link for those who did not attend where I pulled the quote and context from that capital is the deployment bottleneck.

Annual energy transition investment surpassed $2 trillion for the first time in 2024, more than double the rate in 2020, according to research by BloombergNEF examining the deployment of net zero-aligned technologies and infrastructure.

1mo agoHN ↗

This decarbonizes the last 20% of Canada’s electrical generation

I don't think so. Churchill Falls is ~5000km from Alberta

1mo agoHN ↗

Scanning through the link you provided, there's a discussion of interties between neighboring provinces, but there's no way the plan here is to replace Alberta's natural gas with hydro from Labrador, 5 provinces to the east.

There's also an acknowledgment of the continuing need for natural gas (possibly for political reasons). But even in a future where natural gas is phased out, it would be much more logical to use hydro from BC or MB. Alberta could also increase its own solar and wind.

1mo agoHN ↗

At the end of the day, nothing beats hydro electric power. It's hidden, consistent and the technology is very mature. Really the OG of renewable energy. If we could get our appliances running efficiently enough, I think we could run the whole grid on it.

1mo agoHN ↗

Hydro power (dams) causes massive declines in native fish populations in the affected rivers, which is especially significant for salmonids. There have been attempts to mitigate these issues with 'fish ladders' (as well as more complicated schemes), but they haven't been very effective.

1mo agoHN ↗

And they fill up with silt and generate less power over time.

1mo agoHN ↗

which even its architect went on to admit was a mistake.

Who are you referring to? A quick Google search didn't confirm what you wrote.

29d agoHN ↗

A number of prominent Westerners have spoken out against the dam over the years - Republican icon Barry Goldwater, former congressman and interior secretary Stewart Udall, his brother and another former congressman, Mo Udall, and David Brower, a patriarch of the environmental movement.

All supported dam legislation in 1956. All now say it was a mistake. Goldwater calls the dam "the one vote I wish I could take back."

From https://lasvegassun.com/news/1997/may/26/once-proud-symbol-g...

I meant architect as in "political architect"

29d agoHN ↗

Thanks for providing an update, but none of those people were the "architect" in any sense, political or otherwise.

The main person responsible for getting the dam built was Floyd Dominy, and he still supported the dam up to his death, which is why I asked in the first place.

1mo agoHN ↗

Huh? Solar has all of that and doesn't even have moving parts. The only arguable downside is it increases more sunlight absorbed by the earth (as opposed to reflecting it). You may say but what about nighttime - im talking about in aggregate on earth, just like hydro only works well with only water

1mo agoHN ↗

It's really ironic I think that Donald Trump, despite his "drill baby drill" rhetoric and paying billions of dollars to halt wind projects, will likely be responsible for the largest surge in clean energy developments in history.

Trump has shown that the US can not be trusted and is not a reliable ally, and his Iran-scapade, like Russia's invasion of Ukraine before it, has shown every other country that the absolute worst thing you can do is be dependent on energy imports from despotic nations (US now included) and volatile areas of the world. All these countries are racing to wean themselves off fossil fuels as fast as possible, largely due to Trump.

1mo agoHN ↗

largely due to Trump

I know the US has a main character syndrome but this has been going on for decades now, Donald Trump is not responsible for what happens in the rest of the world regardless of what US news says.

China has been adding a United Kingdom's worth of solar for several years now, Pakistan replaced 40% of its energy supply with solar after floods in recent years, Germany over the last 30 days produced 70% of its energy from renewables etc.

"Drill Baby Drill" in 2026 was already the mentality of a Japanese holdout soldier years after the war is over. It's a purely ideological thing.

1mo agoHN ↗

Here in NZ, what Trump has been doing in the Middle East is having a huge impact on policy, especially with the upcoming elections this year. Trump has reminded us (and I imagine many other countries too) that relying on other countries for fuel is fraught with danger. EV sales have spiked here, and all of the political parties are scrambling to come with electrification policies. So for NZ at least, I definitely agree with the OP comment about Trump's influence.

1mo agoHN ↗

it also coincides with the size of the global oat milk market, thank god those hipsters solved the climate problem.

Didn't know we needed to go over causality and correlation. China put itself on the renewable energy path during the 10th and 11th Five year plan, and the so called National Action Plan on Climate change which was ratified in IIRC 2007.

https://chineseclimatepolicy.oxfordenergy.org/book-content/b...

1mo agoHN ↗

I agree with most of what you wrote - the energy transition has been happening for a long time now. Indeed, my argument that Trump's malfeasance is causing countries to accelerate plans for energy independence wouldn't even be possible if costs for renewables hadn't come down drastically in the last few decades.

But it's undeniable that the deglobalization that is occurring, and the closure of the Strait of Hormuz (not to mention issues in the Bab el-Mandeb Strait), is causing many countries to accelerate their plans, if just for the simple reason that the cost pain now makes the economics of renewables all the more favorable.

Well, finally!

One of the reasons I voted for him were his environmental credentials. But what he did since elected was cozying up with Alberta and their oil barons.

1mo agoHN ↗

Carney is one of the most popular "Liberal" PMs west of Ontario in decades. His popularity in Alberta is higher than Daniel Smith. This can only be good for Canada as a whole IMHO.

1mo agoHN ↗

Probably the most evil PMs that we have ever had. Literally a international banker! Its like electing the monopoly man lol.

1mo agoHN ↗

Nope, the pure evil award goes to Stephen Harper. He literally auctioned off and trashed decades of paper scientific research reports to get rid of all of those pesky climate statistics.

26d agoHN ↗

Yes, go back to sleep. I will always be out of fashion when the hip look is being an ostrich with it's head up it's butt.

1mo agoHN ↗

Oh wow. Canadians should have elected PP or Jagmeet with known ties to extremist organizations or maybe give another chance to JT to ruin the country.

1mo agoHN ↗

Not to rain on your parade about known ties to extremist organizations but I would count Carney's contacts more extreme - and certainly more believable - than those Poilievre might be accused of having (which would those be?). I'd rather not have a globalist banker leading my country, fortunately I'm not a Canadian. I considered moving there in 2002 but I moved to Sweden instead and count my blessings ever since.

1mo agoHN ↗

This is a genuinely huge deal, and I think it's worth appreciating why hydro makes sense here specifically, even though the headline cost looks steep. On paper, this project runs around $5M per megawatt of capacity, while utility solar can be built for roughly a fifth of that. But that comparison is misleading once you factor in capacity factor --Churchill Falls runs near 74% of its max output almost all the time, while solar in most places only hits 20-25%. To match the same annual output, you'd need to build solar at more than 3x its nameplate capacity. And even then, batteries only solve the day/night problem. Labrador can get stretches of overcast, snowy weather for a week or more at a time, and multi-day battery storage is still wildly expensive compared to a reservoir that just stores water until it's needed. Try this same approach somewhere sunny and cloud-free like Texas, and solar+storage would almost certainly win, especially when accounting for the land area that needs to be submerged by the reservoir. This project makes sense because it's matched to the geography.

14 Gigawatts for 70 Billion? Is that a good dollar value?

An announcement means nothing unless it is followed through. It's results that matter. Carney likes to make a lot of announcements but there have been no results or even the start of any of these announcements.

I am of the opinion this is much to do about nothing, like every other announcement made by not just Carney but his predecessors. It's all just theater for the masses.

Why not just do it, like they did it decades ago, why does it have to be some kind of announcement or is this just a political ploy to garner more support while doing nothing?

I don't believe anything any of these guys say because talk is cheap and building anything in Canada is nearly impossible.

Junk away....

1mo agoHN ↗

Low balling it is about 10 billion a year CAD in electricity. That is assuming full uptime which is not realistic. It is also going to take several years before these projects complete.

I think the ROI is better than 5% even if you include a variety of factors. Of course if the budgets go >> 70 billion then likely it is a poor investment.

1mo agoHN ↗

    > As part of this agreement, the federal government will provide $10 billion in federal financing to:
    >
    > - Upgrade and expand the Churchill Falls Generating Station.
    > - Develop the massive Gull Island hydroelectricity project.
    > - Unlock co-investment opportunities with the Innu of Labrador in a major new Labrador onshore wind project.
    > - Build associated transmission lines.

70 billion is the combined amount invested from all the parties into all the projects.
