The recent collapse of the power grid in Cuba, plunging the island nation into darkness and grinding its meagre economy to a halt, served as a reminder of electricity’s centrality to modern civilization. That dependency is only expected to increase as more electric vehicles take to the road – and, writes Gwyn Morgan, as the tech sector’s voracious appetite for electrons expands unabated. Morgan pours a pail of cold water on the much-mooted “nuclear revival” that has yet to deliver any actual new electricity. He argues instead that what’s needed is clear-eyed recognition that the most reliable, most abundant, most flexible and most affordable energy source is a fossil fuel located in vast quantities right beneath North Americans’ feet.

Three Mile Island: now there’s a name only us retired folk will remember. On March 28, 1979 the Unit 2 reactor in the Three Mile Island Nuclear Generating Station near Middletown, Pennsylvania incurred a partial melt-down. This was and remains the most serious accident in U.S. nuclear power-plant operating history. Although nobody was killed or injured, the near-catastrophe gripped Americans for months (that was when the term “melt-down” entered the public lexicon). It further energized the powerful anti-nuclear movement – eerily, the movie The China Syndrome concerning a fictional reactor melt-down had been released just 12 days before the actual Three Mile Island event – and shifted public opinion further against generating electricity by splitting the atom. Construction of new facilities slowed dramatically and eventually the number of cancellations – 120 – exceeded the approximately 90 nuclear plants that actually operate; not one was built for 30 years.

Now, 45 years later, comes announcement of a deal by tech giant Microsoft Corporation with Constellation Energy, owner of the infamous Three Mile Island facility, to restart the mothballed nuclear plant’s sister reactor, Unit 1. It will be the first such restart in the U.S.

Nuclear revival? Forty-five years after the infamous partial reactor core melt-down at Three Mile Island (pictured at top left and centre) and release of the sensationalistic anti-nuclear movie The China Syndrome (starring Jane Fonda, pictured at bottom left), the plant’s sister reactor is set for a US$1.6 billion restart to power data centres supporting artificial intelligence (AI).

After all these years, why now? The answer is electricity demand for artificial intelligence (AI). Like many things in the tech realm, AI is a sneakily prodigious consumer of electricity, and AI’s use is exploding. The Microsoft/Constellation project is one of several such deals recently unveiled by tech giants.

A Goldman Sachs report from May of this year illuminates the issue, observing that, “On average, a ChatGPT query needs 10 times as much electricity to process as a Google search.” ChatGPT is a popular AI tool for information research and content creation (college kids particularly love it); a related and even more power-hungry tool spits out sophisticated digital imagery. And ChatGPT is only one of the burgeoning AI applications, which include everything from order processing and customer fulfillment to global shipping, generating sales leads, and helping operate factories and ports. Consequently, says Goldman Sachs, “Our researchers estimate data center power demand will grow 160% by 2030” – representing a remarkable one-third of all growth in U.S. electricity demand. “This increased demand will help drive the kind of electricity growth that hasn’t been seen in a generation,” says the report, which it pegs at a robust 2.4 percent per year during this period.

That’s a lot of juice. So where will all this additional power come from? In the U.S., 60 percent of electricity comes from natural gas and coal. Nuclear energy supplies 19 percent, hydroelectric facilities 6 percent, while wind and solar provide the remaining 14 percent. But wind and solar are intermittent, difficult to scale quickly, geographically limited – and, above all, cannot be counted on for the large-scale, uninterrupted, secure “base load” that AI requires.

And while there is something of a nuclear revival happening in the U.S. and around the world, it will be four years before Three Mile Island comes back on-stream (at an anticipated cost of US$1.6 billion). Such a time-frame even to restart an existing facility underscores the long lead times afflicting the design, construction and commissioning of any technically complex, large-scale and politically controversial infrastructure. There’s a lot of talk about shortening that cycle by focusing on a new generation of “small modular reactors” (SMR), which generate about one-quarter the power of the regular kind. But SMRs remain largely untested and, here too, their lead times are long. Alberta and Saskatchewan, for example, have been talking with other provinces for the last four years about the concept, but haven’t even begun writing the governing regulations, let alone holding public hearings. The most optimistic scenario has the first SMR coming online in 2034.

Realistically, then, most of the growth in power demand for AI will have to be met by fossil fuels, however distasteful this will be to America’s tech moguls, who want to be seen as hip and earth-friendly even if not all of them are actually left-leaning. (A laughable detail of the recent Constellation/Microsoft deal is that Three Mile Island is being renamed the “Crane Clean Energy Center”, as if it’s some kind of Google-style campus.)

Those tech moguls will have to come to terms with natural gas. Natural gas is by far the lowest-emission fossil fuel. It is readily transportable by pipeline around North America. Large-scale gas-fired generating facilities can be built quickly, at reasonable cost and at low risk using mature technology, and can be located almost anywhere. And, fortunately for Americans, natural gas is in robust supply, with production setting new records nearly every year, and is currently cheaper than dirt. Indeed, the Goldman report itself forecasts (too conservatively, in my view) that the growth in electricity demand will in turn trigger “3.3 billion cubic feet per day of new natural gas demand by 2030, which will require new pipeline capacity to be built.”

In Canada, 60 percent of our electricity comes from hydro power, but very few viable new dam sites are left (Quebec recently commissioned a new dam after years of delay, and does have a few additional candidate sites, but these are the rare exceptions). Ontario’s nuclear plants supply 16 percent. Expansion of this is under consideration but, as noted, any new capacity is many years away. Coal and coke supply 8 percent (and are being further scaled back), natural gas 8 percent, and solar and wind 6 percent. So Canada’s growing electricity demand, much of it driven by AI and other tech requirements, will also need to be fuelled by natural gas. Fortunately, Canada too has enormous untapped natural gas reserves, and is also setting new production records.

In contrast to the United States and Canada, Europe is struggling just to meet existing electricity demand after natural gas imports from Russia dropped from 5.5 trillion cubic feet in 2021 to 2.2 trillion cubic feet last year. Europe’s only option is importing liquefied natural gas (LNG). Germany, previously the largest importer of Russian gas – and which in the face of the resulting energy shortage chose to shut down the last of its nuclear plants – is constructing LNG import/regasification terminals on an urgent basis. Regrettably, the situation could get even worse for Europe; China is in talks with Russia that could lead to complete stoppage of remaining gas flows, further escalating Europe’s need for LNG.

That makes meeting the electricity demands of the EU’s smaller but also growing AI sector even more challenging. Moreover, Europe’s power grid is the oldest in the world at 50 years, so it needs both modernization and expansion. The above-quoted Goldman Sachs report states that, “Europe needs $1 trillion [in new investment] to prepare its power grid for AI.” Goldman’s researchers estimate that the continent’s power demand could grow by at least 40 percent in the next ten years, requiring investment of US$861 billion in electricity generation on top of the even higher amount to replace those old transmission systems. The situation is complex and challenging, but one thing is clear: the electricity Europe requires for AI can be fuelled in large part only by natural gas imported from friendly countries.

The AI frenzy may still seem incomprehensible to most Canadians, so it’s important to understand how its applications are spreading through more and more of the economy. Toronto-based Thomson Reuters is a well-known company that provides data and information to professionals across three main industries: legal, tax & accounting, and news & media. A recent Globe and Mail article about Thomson Reuters’ journey from reticence to embrace of the AI world provides helpful perspective. After spending a year of assessment, management concluded that AI was key to the company’s future. Thomson Reuters pledged to spend US$100 million annually to develop its AI capacity. Knowing that this is the cost for just one medium-sized Canadian company puts into perspective the potential scale of AI’s electricity-hungry global growth.

xMore juice needed: As many more companies – like Toronto-based information conglomerate Thomson Reuters – come to understand the need to embrace AI technology, the global appetite for electricity will continue to grow, demand that will only increase with the further advancement of cryptocurrencies and electric vehicles.

Almost forgotten in the electricity-devouring list are cryptocurrencies. In 2020-21 Bitcoin “mining” (the data centres that compete to solve the encrypted blockchains as quickly as possible) consumed more electricity than the 230 million people of Pakistan. Meeting the tech sector’s voracious and – if the growth forecasts are accurate – essentially insatiable demand for electricity will be challenging enough, but there’s another major source of electricity demand growth: electric vehicles (EVs). An International Energy Agency report estimates that EV power needs in the U.S. and Europe will rise from less than 1 percent of electricity demand today to 14 percent in 2030 if electric vehicle mandates are to be met. This C2C article examines the specific implications for Canada.

Who could have imagined that these celebrated new technologies – billed as clean, green and “sustainable” – would end up being the biggest drivers of fossil fuel growth! With our incredible endowment of accessible natural resources, our nation should seize this enormous natural gas export opportunity by getting rid of the bureaucratic time-consuming processes and other roadblocks that have so long discouraged getting new LNG export terminals built and operating.

Jason Kenney and the End of All Things (Or Maybe Just a Democratic Vote)

Time was a former political leader’s expected role was to enjoy retirement in obscurity, reappearing at the occasional state funeral or apolitical charity event smiling inscrutably and saying nothing. While former U.S. President Bill Clinton broke this mould and fellow Democrat Barack Obama won’t stop delivering lectures, conservatives generally stick to tradition. Former Alberta Premier Jason Kenney, however, just can’t help himself – literally. Collin May probes the curious, maddening and somewhat sad case of a once-respected leader who, having dug his own political grave, now seems to think the way out is to keep shovelling.

On the Murder of Charlie Kirk: The Left and the Loss of the Tragic Sensibility

The brutal assassination of Charlie Kirk was shocking not only for its violence but for the chilling aftermath – the celebrations on the left, the gloating and the calls for more political violence. In searching for an explanation, Patrick Keeney argues that our culture has lost what Western thinkers long recognized as the “tragic vision” of human life – the idea that suffering is inevitable and even central to the human condition. Without that understanding of innate limits, politics no longer is about compromise or making the best of things but becomes pursuit of a utopia where the righteous are justified in demonizing and destroying their opponents. What is now desperately needed, Keeney argues, is a cultural renewal that accepts the tragedy of life and cultivates courage, charity and, above all, humility.

The Law Society of Alberta’s Wokism Will Dissolve the Rule of Law

Lawyers are supposed to defend their clients, the Constitution and the rule of law. But they’re increasingly under pressure from their own regulators to make a political ideology paramount: wokism. It’s a problem across the country, and it’s not limited to the legal profession: teachers, psychologists, nurses and more must now submit to political re-education and push woke principles in their work, while their political speech as private citizens is increasingly policed. This phenomenon is most dangerous in the law: if lawyers change Canada’s “legal culture” to centre woke victimology, they will effectively undermine the law and the Constitution. In this powerful essay, Glenn Blackett uncovers the woke takeover of the Law Society of Alberta and tells the story of the heroic lawyer fighting back: a “recovered Communist” horrified to see the ideological tyranny he experienced as a young man now being applied in Canada.

Dead Wait: Canada’s Fatal Obsession with Public Health Care

Canada spends more on health care than just about any other country in the world, and with abysmal results. Yet when it comes to fixing the problem, most politicians and policy-makers are immune to common sense. As business leader Gwyn Morgan writes, allowing private options alongside government-funded health care has been proven to help patients in both systems – around the world and here in Canada, too. Yet the courts continued to uphold restrictions on private care while the Mark Carney government simply promises to throw still more money at the problem – showing itself to be as deluded and dogmatic as those who went before.

“Owe Canada”: Our Nation’s Looming Fiscal Abyss

For anyone who still bought into Mark Carney’s self-declared image as the great global banker who would responsibly manage Canada’s finances, his recent promise to juice defence spending to 5 percent of GDP – $155 billion per year in today’s dollars – must surely be the final straw. The Liberal Prime Minister had already announced massive spending hikes and a huge deficit, with interest on the federal debt to hit $70 billion by 2029. All this will spell doom for a country already struggling with declining productivity, zero growth and a falling standard of living, concludes Gwyn Morgan. The veteran business leader charts Canada’s path to budgetary disaster and places the blame squarely where it belongs – on Canada’s profligate Prime Minister.

Restoring Canada Special Series
Part II: Carney’s Energy Policy and the Fragile Canadian Economy

“Meet the new boss/Same as the old boss,” The Who’s Pete Townshend wrote back in 1971. Words that today might well apply to Mark Carney. Canada’s new Liberal Prime Minister says he wants to make Canada a “conventional and clean energy superpower”, and suddenly seems to support new oil and natural gas pipelines. But Gwyn Morgan, who devoted years as a CEO to defending Canada’s oil and natural gas industry, doesn’t buy it. Carney, he notes, spent years abroad on an ever-more-strident net-zero quest, and recently said he’s keeping his predecessor’s oil and gas emissions cap in place. In this incisive critique, Morgan takes the measure of the new PM and finds that the prospects of restoring the Canadian economy have dimmed further.
