Net Zero by 2050: There is no realistic path to affordable and reliable electricity

Maintaining energy diversity is crucial to a truly sustainable future

Canada is on an ambitious path to “decarbonize” its economy by 2050 to deliver on its political commitment to achieve net-zero greenhouse gas (GHG) emissions. Although policy varies across provinces and federally, a default policy of electrification has emerged, and the electricity industry, which in Canada is largely owned by our provincial governments, appears to be on board.

In a November 2023 submission to the federal government, Electricity Canada, an association of major electric generators and suppliers in Canada, stated: “Every credible path to Net Zero by 2050 relies on electrification of other sectors.” In a single generation, then, will clean electricity become the dominant source of energy in Canada? If so, this puts all our energy eggs in one basket. Lost in the debate seem to be considerations of energy diversity and its role in energy system reliability.

What does an electrification strategy mean for Canada? Currently, for every 100 units of energy we consume in Canada, over 40 come to us as liquid fuels like gasoline and diesel, almost 40 as gaseous fuels like natural gas and propane, and a little less than 20 in the form of electrons produced by those fuels as well as by water, uranium, wind, solar and biomass. In British Columbia, for example, the gas system delivered approximately double the energy of the electricity system.

How much electricity will we need? According to a recent Fraser Institute report, a decarbonized electricity grid by 2050 requires a doubling of electricity. This means adding the equivalent of 134 new large hydro projects like BC’s Site C, 18 nuclear facilities like Ontario’s Bruce Power Plant, or installing almost 75,000 large wind turbines on over one million hectares of land, an area nearly 14.5 times the size of the municipality of Calgary.

Is it feasible to achieve a fully decarbonized electricity grid in the next 25 years that will supply much of our energy requirements? There is a real risk of skilled labour and supply chain shortages that may be impossible to overcome, especially as many other countries are also racing towards net-zero by 2050. Even now, shortages of transformers and copper wire are impacting capital projects. The Fraser Institute report looks at the construction challenges and concludes that doing so “is likely impossible within the 2050 timeframe”.

How we get there matters a lot to our energy reliability along the way. As we put more eggs in the basket, our reliability risk increases. Pursuing electrification while not continuing to invest in our existing fossil fuel-based infrastructure risks leaving our homes and industries short of basic energy needs if we miss our electrification targets.

The IEA 2023 Roadmap to Net Zero estimates that technologies not yet available on the market will be needed to deliver 35 percent of emissions reductions needed for net zero in 2050.  It comes then as no surprise that many of the technologies needed to grow a green electric grid are not fully mature. While wind and solar, increasingly the new generation source of choice in many jurisdictions, serve as a relatively inexpensive source of electricity and play a key role in meeting expanded demand for electricity, they introduce significant challenges to grid stability and reliability that remain largely unresolved. As most people know, they only produce electricity when the wind blows and the sun shines, thereby requiring a firm back-up source of electricity generation.

Given the unpopularity of fossil fuel generation, the difficulty of building hydro and the reluctance to adopt nuclear in much of Canada, there is little in the way of firm electricity available to provide that backup. Large “utility scale” batteries may help mitigate intermittent electricity production in the short term, but these facilities too are immature. Furthermore, wind, solar and batteries, because of the way they connect to the grid don’t contribute to grid reliability in the same way the previous generation of electric generation does.

Other zero-emitting electricity generation technologies are in various stages of development – for example, Carbon Capture Utilization and Storage (CCUS) fitted to GHG emitting generation facilities can allow gas or even coal to generate firm electricity and along with Small Modular Reactors (SMRs) can provide a firm and flexible source of electricity.

What if everything can’t be electrified? In June 2024, a report commissioned by the federal government concluded that the share of overall energy supplied by electricity will need to roughly triple by 2050, increasing from the current 17 percent to between 40 and 70 percent. In this analysis, then, even a tripling of existing electricity generation, will at best only meet 70 percent of our energy needs by 2050.

Therefore, to ensure the continued supply of reliable energy, non-electrification pathways to net zero are also required. CCUS and SMR technologies currently being developed for producing electricity could potentially be used to provide thermal energy for industrial processes and even building heat; biofuels to replace gasoline, diesel and natural gas; and hydrogen to augment natural gas, along with GHG offsets and various emission trading schemes are similarly

While many of these technologies can and currently do contribute to GHG emission reductions, uncertainties remain relating to their scalability, cost and public acceptance. These uncertainties in all sectors of our energy system leaves us with the question: Is there any credible pathway to reliable net-zero energy by 2050?

Electricity Canada states: “Ensuring reliability, affordability, and sustainability is a balancing act … the energy transition is in large part policy-driven; thus, current policy preferences are uniquely impactful on the way utilities can manage the energy trilemma. The energy trilemma is often referred to colloquially as a three-legged stool, with GHG reductions only one of those legs. But the other two, reliability and affordability, are key to the success of the transition.

Policymakers should urgently consider whether any pathway exists to deliver reliable net-zero energy by 2050. If not, letting the pace of the transition be dictated by only one of those legs guarantees, at best, a wobbly stool. Matching the pace of GHG reductions with achievable measures to maintain energy diversity and reliability at prices that are affordable will be critical to setting us on a truly sustainable pathway to net zero, even if it isn’t achieved by 2050.

Fuelled by federalism—America’s economically freest states come out on top

Published on

From the Fraser Institute

By Matthew D. Mitchell

Do economic rivalries between Texas and California or New York and Florida feel like yet another sign that America has become hopelessly divided? There’s a bright side to their disagreements, and a new ranking of economic freedom across the states helps explain why.

As a popular bumper sticker among economists proclaims: “I heart federalism (for the natural experiments).” In a federal system, states have wide latitude to set priorities and to choose their own strategies to achieve them. It’s messy, but informative.

New York and California, along with other states like New Mexico, have long pursued a government-centric approach to economic policy. They tax a lot. They spend a lot. Their governments employ a large fraction of the workforce and set a high minimum wage.

They aren’t socialist by any means; most property is still in private hands. Consumers, workers and businesses still make most of their own decisions. But these states control more resources than other states do through taxes and regulation, so their governments play a larger role in economic life.

At the other end of the spectrum, New Hampshire, Tennessee, Florida and South Dakota allow citizens to make more of their own economic choices, keep more of their own money, and set more of their own terms of trade and work.

They aren’t free-market utopias; they impose plenty of regulatory burdens. But they are economically freer than other states.

These two groups have, in other words, been experimenting with different approaches to economic policy. Does one approach lead to higher incomes or faster growth? Greater economic equality or more upward mobility? What about other aspects of a good society like tolerance, generosity, or life satisfaction?

For two decades now, we’ve had a handy tool to assess these questions: The Fraser Institute’s annual “Economic Freedom of North America” index uses 10 variables in three broad areas—government spending, taxation, and labor regulation—to assess the degree of economic freedom in each of the 50 states and the territory of Puerto Rico, as well as in Canadian provinces and Mexican states.

It’s an objective measurement that allows economists to take stock of federalism’s natural experiments. Independent scholars have done just that, having now conducted over 250 studies using the index. With careful statistical analyses that control for the important differences among states—possibly confounding factors such as geography, climate, and historical development—the vast majority of these studies associate greater economic freedom with greater prosperity.

In fact, freedom’s payoffs are astounding.

States with high and increasing levels of economic freedom tend to see higher incomesmore entrepreneurial activity and more net in-migration. Their people tend to experience greater income mobility, and more income growth at both the top and bottom of the income distribution. They have less poverty, less homelessness and lower levels of food insecurity. People there even seem to be more philanthropic, more tolerant and more satisfied with their lives.

New Hampshire, Tennessee, and South Dakota topped the latest edition of the report while Puerto Rico, New Mexico, and New York rounded out the bottom. New Mexico displaced New York as the least economically free state in the union for the first time in 20 years, but it had always been near the bottom.

The bigger stories are the major movers. The last 10 years’ worth of available data show South Carolina, Ohio, Wisconsin, Idaho, Iowa and Utah moving up at least 10 places. Arizona, Virginia, Nebraska, and Maryland have all slid down 10 spots.

Over that same decade, those states that were among the freest 25 per cent on average saw their populations grow nearly 18 times faster than those in the bottom 25 per cent. Statewide personal income grew nine times as fast.

Economic freedom isn’t a panacea. Nor is it the only thing that matters. Geography, culture, and even luck can influence a state’s prosperity. But while policymakers can’t move mountains or rewrite cultures, they can look at the data, heed the lessons of our federalist experiment, and permit their citizens more economic freedom.

Politicians should be honest about environmental pros and cons of electric vehicles

Published on

From the Fraser Institute

By Annika Segelhorst and Elmira Aliakbari

According to Steven Guilbeault, former environment minister under Justin Trudeau and former member of Prime Minister Carney’s cabinet, “Switching to an electric vehicle is one of the most impactful things Canadians can do to help fight climate change.”

And the Carney government has only paused Trudeau’s electric vehicle (EV) sales mandate to conduct a “review” of the policy, despite industry pressure to scrap the policy altogether.

So clearly, according to policymakers in Ottawa, EVs are essentially “zero emission” and thus good for environment.

But is that true?

Clearly, EVs have some environmental advantages over traditional gasoline-powered vehicles. Unlike cars with engines that directly burn fossil fuels, EVs do not produce tailpipe emissions of pollutants such as nitrogen dioxide and carbon monoxide, and do not release greenhouse gases (GHGs) such as carbon dioxide. These benefits are real. But when you consider the entire lifecycle of an EV, the picture becomes much more complicated.

Unlike traditional gasoline-powered vehicles, battery-powered EVs and plug-in hybrids generate most of their GHG emissions before the vehicles roll off the assembly line. Compared with conventional gas-powered cars, EVs typically require more fossil fuel energy to manufacture, largely because to produce EVs batteries, producers require a variety of mined materials including cobalt, graphite, lithium, manganese and nickel, which all take lots of energy to extract and process. Once these raw materials are mined, processed and transported across often vast distances to manufacturing sites, they must be assembled into battery packs. Consequently, the manufacturing process of an EV—from the initial mining of materials to final assembly—produces twice the quantity of GHGs (on average) as the manufacturing process for a comparable gas-powered car.

Once an EV is on the road, its carbon footprint depends on how the electricity used to charge its battery is generated. According to a report from the Canada Energy Regulator (the federal agency responsible for overseeing oil, gas and electric utilities), in British Columbia, Manitoba, Quebec and Ontario, electricity is largely produced from low- or even zero-carbon sources such as hydro, so EVs in these provinces have a low level of “indirect” emissions.

However, in other provinces—particularly Alberta, Saskatchewan and Nova Scotia—electricity generation is more heavily reliant on fossil fuels such as coal and natural gas, so EVs produce much higher indirect emissions. And according to research from the University of Toronto, in coal-dependent U.S. states such as West Virginia, an EV can emit about 6 per cent more GHG emissions over its entire lifetime—from initial mining, manufacturing and charging to eventual disposal—than a gas-powered vehicle of the same size. This means that in regions with especially coal-dependent energy grids, EVs could impose more climate costs than benefits. Put simply, for an EV to help meaningfully reduce emissions while on the road, its electricity must come from low-carbon electricity sources—something that does not happen in certain areas of Canada and the United States.

Finally, even after an EV is off the road, it continues to produce emissions, mainly because of the battery. EV batteries contain components that are energy-intensive to extract but also notoriously challenging to recycle. While EV battery recycling technologies are still emerging, approximately 5 per cent of lithium-ion batteries, which are commonly used in EVs, are actually recycled worldwide. This means that most new EVs feature batteries with no recycled components—further weakening the environmental benefit of EVs.

So what’s the final analysis? The technology continues to evolve and therefore the calculations will continue to change. But right now, while electric vehicles clearly help reduce tailpipe emissions, they’re not necessarily “zero emission” vehicles. And after you consider the full lifecycle—manufacturing, charging, scrapping—a more accurate picture of their environmental impact comes into view.
