Opinion: A least-cost energy strategy would bring Carney’s climate policy home

It’ll be hard for PM Carney to get behind new fossil fuel or nuclear megaprojects without abandoning the aura of economic realism behind the near-heroic reputation he’s built to date.

In May 2024, Mark Carney advised parliamentarians to create a “virtuous circle of large-scale investment, faster decarbonization, more jobs, and faster growth.” The Canadian Press photo by Justin Tang.

Prime Minister Mark Carney and his new cabinet took office Friday with some tough, momentous questions on their agenda, most of them pointing back to the rogue regime waging economic war on Canada from the White House.

But there’s one fairly easy calculation they or any future cabinet can make that will set them on track to addressing that challenge. Not least by tackling the domestic vulnerabilities that were driving us apart until Donald Trump’s latest round of rolling outrages pulled us back together.

What’s the cheapest, quickest way to deliver the reliable, affordable energy Canadians need, while boosting domestic manufacturing, driving down climate pollution, and restoring public confidence that our governments can actually deliver on their promises?

If our political leaders answered that question seriously and followed the evidence where it leads, it would bring them directly to the low-carbon energy path we laid out in last week’s Weekender:

• Drastically increasing the energy efficiency of everything;

• Replacing fuels with electricity across a large swath of the economy while decarbonizing the electricity system;

• Seizing the urgent opportunity to rapidly drive down methane emissions, whether or not fossil companies are serious about getting with the program;

• Pairing the rise of renewables and energy efficiency with a managed phaseout of oil, gas, and coal.

A least-cost energy strategy that factored in the fully-loaded cost of climate change would give us a lens for assessing every new pitch for Canada’s energy future—whether it’s a deep energy retrofit program, a local battery storage system, a solar or wind farm, a $100-billion nuclear megaproject, or the ridiculous demands for new pipelines in all directions, hatched by the fossil fuel industry and voiced by the former industry lobbyist they’ve since installed as Alberta’s premier.

Pretty much without exception, it brings us back to low-carbon options that are practical, affordable, ready to scale up, and won’t either fry the planet when used as directed or saddle us with eons’ worth of dangerous nuclear waste.

For bonus points, it connects us to a burgeoning global clean energy economy—at just the moment when we’re looking to diversity our exports beyond one risky, unreliable trading partner.

And just as important, it takes us past the disconnect between statement and action—between the “what” and the “how” of government policy on climate, affordability, and everything else that matters. That gap has cut across all the major political parties for the last decade and quite rightly sapped public confidence that anything much will ever get done.
