Coal remains the primary fuel for global electricity generation, particularly in Asian countries

High energy prices, inflation, war, and the ongoing economic recovery from the pandemic has highlighted the general worldwide demand for electricity, particularly in Asia and Europe. The growing demand for electricity on these two continents has led some electricity producing plants to rely increasingly heavily on coal as a power source.

The electricity sector accounts for 34 per cent of the world’s energy-related carbon dioxide (CO2) emissions. In this Fact Sheet, we detail recent trends in electricity production and demand across the globe as well as CO2 emissions from the electricity sector worldwide.

Carbon dioxide emissions from the world’s top ten emitters between 2000 and 2022

A total of 38.2 gigatonnes (Gt) of energy-related CO2 was emitted globally in 2022, an increase of 53 per cent from 2000. However, the increase is not consistent for all countries; between 2000 and 2023, CO2 emissions trends diverged. Emissions from China, India, and Indonesia more than doubled in the last two decades, whereas emissions for other countries remained relatively consistent or even declined.

In 2022, Canada’s total energy-related CO2 emissions were 0.62 Gt, or 1.6 per cent of the global total. That compares to emissions of 0.64 Gt in South Korea, 1.09 Gt in Japan, 2.8 Gt in India, 5.0 Gt in the United States, and 13.0 Gt in China (see Figure 1).

Demand for electricity and sources of emissions

Global domestic electricity consumption increased from 13,188 terawatt-hours (TWh) in 2000 to 25,681 TWh in 2022 and estimates are that global demand for electricity will rise to 35,000 TWh by 2040.¹

That is a jump of 94 per cent, or 12,492 TWh, between 2000 and 2022. During the same period, electricity consumption in Asia rose a whopping 280 per cent. In Africa the demand for electricity increased by 90 per cent (see Figure 2). Coal remains the world’s largest source of fuel for electricity generation, with approximately 10,317 terawatt-hours of electricity generated by coal-fired plants in 2022 (see Figure 3).

In recent years, electricity generated from the combustion of coal declined in Canada, the United States, Europe, and Africa. However, electricity generated from coal combustion has continued to grow in China, India, and other parts of Asia.

Between 2000 and 2022, the share of coal-powered electricity generation in Asia increased from 49.8 to 56. 3 per cent, while in Canada it decreased from 19.4 per cent to less than 5 per cent.

Source of emissions in the electricity sector

The electricity sector accounts for 34 per cent of the carbon dioxide emitted across the world. The sector emitted 13.05 gigatonnes of CO2 in 2022, an increase of 5.01 Gt from 2000. In Asia, between 2000 and 2022, CO2 emissions from the electricity sector increased from 2.5 Gt to 8.3 Gt and the sector’s share of carbon dioxide (CO2) emissions increased from just over 32 per cent to well over 40 per cent (see Figure 5).

Sources: IEA World Energy Statistics database and Enerdata

Coal burned to generate electricity accounts for the majority of the CO2 emitted in power generation. In 2022, coal-fired electricity\ generation accounted for 9.89 Gt, or nearly 76 per cent of the worldwide CO2 emissions from the electricity sector. The share was even higher in Asia where 92 per cent of emissions from the electricity sector come from coal combustion. Asian coal-fired plants accounted for 7.62 Gt of the total 8.26 Gt of emissions from the sector on that continent (see Figure 6).

Conclusion

The global electricity sector, and particularly the sector in Asia, is a major source of CO2 emissions. Relative to Canada’s existing carbon emissions, emissions from the coal-fired power plants worldwide will make any reductions in Canada’s carbon emissions and resulting job losses, higher taxes, and higher costs for consumers and businesses—meaningless.

As 56 per cent of the electricity in Asia is generated by coal-fired plants, a transition from coal- to gas-fired electricity generation in the region could lead to significant reductions in CO2 emissions, reducing emissions by 50 per cent on average. The corollary is that there is a potential market in Asia for natural gas extracted in and exported from Canada. Canada has an opportunity to play a useful and meaningful role in reducing CO2 emissions from the electricity sector by encouraging and contributing to the global natural gas market.

Start-up of Trans Mountain expansion ‘going very well’ as global buyers ink deals for Canadian crude

Canada’s oil sands producers are “back in the limelight” for investors following completion of the Trans Mountain pipeline expansion, according to a report by Enervus Intelligence Research.

For the first time in the better part of a decade, there is now breathing room on the system to ship all of the oil producers are able to sell off the coast of B.C.

Up until this May, Trans Mountain was regularly overbooked. Not anymore.

The crude carrier Dubai Angel picked up the first shipment from the long-awaited expansion on May 22, setting sail for China and a customer of oil sands producer Suncor Energy.

Analysts estimate Trans Mountain loaded 20 vessels in June, compared to a pre-expansion average of five per month.

“You’re seeing multiple buyers. It’s going very well,” said Phil Skolnick, managing director of research with New York-based Eight Capital.

“You’re seeing the exact buyers that we always thought were going to show up, the U.S. west coast refineries and as well as the Asian refineries, and there was a shipment that went to India as well.”

Canadian crude in demand on the global market

Asian markets – particularly China, where refineries can process “substantial quantities” of extra heavy crude and bitumen – are now “opened in earnest” to Canadian oil, the International Energy Agency (IEA) said in its June Oil 2024 report.

“There’s demand for this crude and people are going to make deals,” said Kevin Birn, chief analyst of Canadian oil markets with S&P Global.

The IEA said Canadian crude will increasingly compete with heavy oil from other countries, particularly those in Latin America and the Middle East.

June’s loading of 20 vessels is slightly lower than the 22 vessels Trans Mountain had targeted, but Skolnick said a few bumps in the project’s ramp-up are to be expected.

“About three months ago, the shippers were telling investors on their calls, don’t expect it to be a smooth ramp up, it’s going to be a bit bumpy, but I think they’re expecting by Q4 you should start seeing everyone at peak rates,” Skolnick said.

Delivering higher prices

Trans Mountain’s expanded Westridge Terminal at Burnaby, B.C. now has capacity to load 34 so-called “Aframax” vessels each month.

One of the first deals, with Chinese refiner Rongsheng Petrochemical, indicates the Trans Mountain expansion is delivering on one of its expected benefits – higher prices for Canadian oil.

Canada’s Parliamentary Budget Office has said that an increase of US$5 per barrel for Canadian heavy oil over one year would add $6 billion to Canada’s economy.

The June deal between Rongsheng and an unnamed oil sands shipper saw a shipment of Access Western Blend (AWB) purchased for approximately US$6 per barrel below the Brent global oil benchmark. That implies an AWB selling price of approximately US$75 per barrel, or about US$10 more than the price received for AWB in Alberta.

More pipeline capacity needed

Oil sands production – currently about 3.4 million barrels per day – is projected to rise to 3.8 million barrels per day by the end of the decade before declining slightly to about 3.6 million barrels per day in 2035, according to the latest outlook by S&P Global.

“Despite the recent completion of the Trans Mountain Expansion project, additional capacity will still be needed, likely via expansion or optimization of the existing pipeline system,” wrote Birn and S&P senior research analyst Celina Hwang in May.

“By 2026, we forecast the need for further export capacity to ensure that the system remains balanced on pipeline economics.”

Uncertainty over the federal government’s proposed oil and gas emissions cap “adds hesitation” to companies considering large-scale production growth, wrote Birn and Hwang.

Global oil demand rising

World oil demand, which according to the IEA reached a record 103 million barrels per day in 2023, is projected to continue rising despite increased investment in renewable and alternative energy.

June outlook by the International Energy Forum (IEF) pegs 2030 oil demand at nearly 110 million barrels per day.

“More investment in new oil and gas supply is needed to meet growing demand and maintain energy market stability, which is the foundation of global economic and social well-being,” said IEF secretary Joseph McMonigle.

What’s next? With major projects wrapping up, what does Canada’s energy future hold

Published on

From the Canadian Energy Centre

‘This is the first time Canada will enter the global marketplace as a global player, so it is an incredibly important change for the industry’

With the recent completions of the Trans Mountain expansion and Coastal GasLink pipelines, and the looming completion of LNG Canada within the next year, there are few major energy projects with the green light for one of the world’s largest and most responsible energy producers.

Which leaves a lingering question: In a world that has put a premium on energy security, what’s next for Canada?

Heather Exner-Pirot, a senior fellow and director of the natural resources, energy and environment program at the Macdonald-Laurier Institute, said Natural Resources Canada’s major projects inventory “has been in a pretty sharp decline since 2015, which is concerning.”

“It’s not just oil and gas but also mining, also electricity . . . It’s the overall context for investment in Canada,” said Exner-Pirot, who is also a special adviser to the Business Council of Canada.

“When we look at BC, we see TMX, Coastal GasLink, very soon LNG Canada will be finishing up. That’s probably in the order of $100 billion of investment that that province will lose.

“So you do start to think about what happens next. But there are some things on the horizon. I think that’s part of it. Other LNG projects where maybe it wasn’t politically popular, it wasn’t a social license, and maybe the labour force was also constrained, and now is opening opportunities.”

recent analysis conducted by Exner-Pirot found that between 2015 and 2023, the number of energy and natural resource major projects completed in Canada dropped by 37 per cent. And those that managed to be completed often faced significant delays and cost overruns.

One notable project Exner-Pirot expects to fill the void is Ksi Lisims LNG, which is being developed on the northwest coast of Canada to export low-carbon LNG to markets in Asia. The project represents a unique alliance between the Nisga’a Nation, Rockies LNG and Western LNG.

Ksi Lisims LNG is a proposed floating LNG export facility located on a site owned by the Nisga’a Nation near the community of Gingolx in British Columbia.

The project will have capacity to produce 12 million tonnes of LNG per year, destined for markets in the Pacific basin, primarily in Asia where demand for cleaner fuels to replace coal continues to grow.

As well, the second phase of the LNG Canada export terminal in Kitimat, B.C. shows increasing signs of moving forward, which would roughly double its annual production capacity from 14 million tonnes to 26 million tonnes, Exner-Pirot added.

While nearby, Cedar LNG, the world’s first Indigenous-owned LNG export facility, is closing in on the finish line with all permits in place and early construction underway. When completed, the facility will produce up to three million tonnes of LNG annually, which will be able to reach customers in Asia, and beyond.

According to the International Energy Agency, the world is on track to use more oil in 2024 than last year’s record-setting mark. Demand for both oil and natural gas is projected to see gradual growth through 2050, based on the most likely global scenario.

Kevin Birn, chief analyst for Canadian oil markets at S&P Global, said despite the Trans Mountain expansion increasing Canada’s oil export capacity by 590,000 barrels per day, conversations have already begun around the need for more infrastructure to export oil from western Canada.

“The Trans Mountain pipeline, although it’s critical and adds the single largest uplift in oil capacity in one swoop, we see production continue to grow, which puts pressures on that egress system,” he said.

Birn said Canada remains a major global player on the supply side, being the world’s fourth-largest producer of oil and fifth-largest producer of natural gas.

“This is a really important period for Canada. These megaprojects, they’re generational. These are a once-in-a-generation kind of thing,” Birn said.

“For Canada’s entire history of being an oil and gas producer, it’s been almost solely reliant on one single export market, which is the United States. That’s been beneficial, but it’s also caused problems for Canada in that reliance from time to time.

“This is the first time Canada will enter the global marketplace as a global player, so it is an incredibly important change for the industry.”

Exner-Pirot said Canada has the ability to become a major exporter on the energy front globally, at a time when demand is accelerating.

“We have open water from B.C. to our allies in Asia . . . It’s a straight line from Canada to its allies. This is a tremendous advantage,” she said, noting the growth of data centres and AI is expected to see demand for reliable energy soar.

“We are seeing growing electricity demand after decades of plateauing because our fridges got more energy efficient and our washers and dryers got more energy efficient. Now we’re starting to see for the first time in a long time more electricity demand even in developed countries. These are all drivers.”
