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.

AI-driven data centre energy boom ‘open for business’ in Alberta

Published on

From the Canadian Energy Centre

By Deborah Jaremko and Will Gibson

“These facilities need 24/7, super-reliable power, and there’s only one power generation fuel that has any hope of keeping up with the demand surge: natural gas”

Data centres – the industrial-scale technology complexes powering the world’s growing boom in artificial intelligence – require reliable, continuous energy. And a lot of it.

“Artificial Intelligence is the next big thing in energy, dominating discussions at all levels in companies, banks, investment funds and governments,” says Simon Flowers, chief analyst with energy consultancy Wood Mackenzie.

The International Energy Agency (IEA) projects that the power required globally by data centres could double in the next 18 months. It’s not surprising given a search query using AI consumes up to 10 times the energy as a regular search engine.

The IEA estimates more than 8,000 data centres now operate around the world, with about one-third located in the United States. About 300 centres operate in Canada.

It’s a growing opportunity in Alberta, where unlike anywhere else in the country, data centre operators can move more swiftly by “bringing their own power.”

In Alberta’s deregulated electricity market, large energy consumers like data centres can build the power supply they need by entering project agreements directly with electricity producers instead of relying solely on the power of the existing grid.

Between 2018 and 2023, data centres in Alberta generated approximately $1.3 billion in revenue, growing on average by about eight percent per year, lawyers with Calgary-based McMillan LLP wrote in July.

“Alberta has a long history of building complex, multi-billion-dollar infrastructure projects with success and AI data centres could be the next area of focus for this core competency,” McMillan’s Business Law Bulletin reported.

In recent years, companies such as Amazon and RBC have negotiated power purchase agreements for renewable energy to power local operations and data centres, while supporting the construction of some of the country’s largest renewable energy projects, McMillan noted.

While the majority of established data centres generally have clustered near telecommunications infrastructure, the next wave of projects is increasingly seeking sites with electricity infrastructure and availability of reliable power to keep their servers running.

The intermittent nature of wind and solar is challenging for growth in these projects, Rusty Braziel, executive chairman of Houston, Texas-based consultancy RBN Energy wrote in July

“These facilities need 24/7, super-reliable power, and there’s only one power generation fuel that has any hope of keeping up with the demand surge: natural gas,” Braziel said.

TC Energy chief operating officer Stan Chapman sees an opportunity for his company’s natural gas delivery in Canada and the United States.

“In Canada, there’s around 300 data centre operations today. We could see that load increasing by one to two gigawatts before the end of the decade,” Chapman said in a conference call with analysts on August 1.

“Never have I seen such strong prospects for North American natural gas demand growth,” CEO François Poirier added.

Alberta is Canada’s largest natural gas producer, and natural gas is the base of the province’s power grid, supplying about 60 percent of energy needs, followed by wind and solar at 27 percent.

“Given the heavy power requirements for AI data centres, developers will likely need to bring their own power to the table and some creative solutions will need to be considered in securing sufficient and reliable energy to fuel these projects,” McMillan’s law bulletin reported.

The Alberta Electric System Operator (AESO), which operates the province’s power grid, is working with at least six proposed data centre proposals, according to the latest public data.

“The companies that build and operate these centres have a long list of requirements, including reliable and affordable power, access to skilled labour and internet connectivity,” said Ryan Scholefield, the AESO’s manager of load forecasting and market analytics.

“The AESO is open for business and will work with any project that expresses an interest in coming to Alberta.”

Canada’s first liquefied natural gas export terminal ‘on the cusp’ of its testing phase

Momentum is building for the long-awaited start-up of Canada’s first liquefied natural gas (LNG) export project.

Shipments from the LNG Canada terminal at Kitimat, B.C. may now start earlier than expected, later this year rather than mid-2025, according to Martin King, Canadian energy specialist with Houston-based RBN Energy.

“LNG Canada appears to be on the cusp of its testing phase and is likely to be exporting some cargoes of LNG before the end of this year,” King wrote recently.

He made the prediction after a senior executive with Shell, the project’s lead owner, said it could deliver its first cargo earlier than previously planned, in the wake of two key milestones.

Fluor reported in July it had completed the final weld on the first production train while Petronas, which holds a 25 per cent stake in LNG Canada, announced it would add three LNG vessels to its North American fleet, doubling its size.

A longtime industry insider sees the $18 billion LNG Canada terminal as a game changer.

“This is decades in the making. Canada has been trying to get its LNG business up and running since the 1970s but it has been sidetracked for one reason or another,” says Calgary-based consultant Racim Gribaa, who has worked in the industry for more than 25 years.

“This project is perfectly placed to take advantage of an awesome opportunity given the demand for LNG worldwide is growing exponentially.”

The project, which will use the Coastal GasLink pipeline, completed in November 2023, to bring gas from northeastern British Columbia to the Kitimat terminal for processing and shipping, will have capacity to produce up to 14 million tonnes per year in its first phase.

While that’s a fraction of the 404 million tonnes of global demand in 2023, Gribaa says Asian buyers view LNG Canada as secure supplier in part due to its geography.

“The closest point to Asia is Canada’s west coast, so you have the shortest shipping route, which makes for optimal transportation costs. The traders and LNG industry see it as valuable for that reason,” says Gribaa, who previously worked in LNG trade in Qatar, one of the world’s largest exporters.

And the project is coming online at a time when worldwide demand is surging.

“The worldwide demand has effectively doubled every decade since 1990, when it was 50 MPTA. We are now closing in on 500 MPTA and that is accelerating,” Gribaa says.

“The world will need 10 LNG Canadas in 10 years and 100 more LNG Canadas in the next 30 years.”

The project has plans for a second phase that would double production to 28 million tonnes per year. Based on demand, Gribaa says “the question isn’t if it will go forward, it’s when the consortium will announce the expansion.”

World LNG demand growth will be particularly strong in Asia, where Shell’s four LNG Canada partners – Petronas (25 per cent), PetroChina (15 per cent), Mitsubishi (15 per cent) and Korea Gas Corporation (five per cent) – are headquartered.

“Each of these markets has historical demand for LNG and that demand will continue to grow in the coming decades,” he says, adding that LNG in Asia can be used for power generation and heavy industry, and to reduce air pollution from coal-fired power.

Overall, generating electricity in China with LNG from Canada rather than coal could reduce emissions by up to 62 per cent, according to a 2020 study published in the Journal for Cleaner Production.

A 2022 study by Wood Mackenzie found that growing Canada’s LNG industry could reduce net emissions in Asia by 188 million tonnes per year through 2050.
