The Japan Times - The world built more coal power in 2025, but used less

Coal is a key contributor to planet-warming greenhouse gas emissions, and phasing it out is crucial to taming climate change.

The growing affordability and abundance of renewable energy means solar and wind power can now cover growing electricity demand in much of the world.

That helped push coal generation down globally by 0.6 percent in 2025 from a year earlier, according to a new report from Global Energy Monitor, which has tracked coal power for more than a decade.

But despite the generation drop, coal power capacity -- plants that came online or were commissioned -- jumped 3.5 percent last year.

The overwhelming majority of that -- 95 percent -- was in China and India, GEM said.

China's coal capacity grew six percent last year, but coal-powered electricity generation fell 1.2 percent, in part because of soaring renewable capacity.

The same was true in India, where capacity grew almost four percent, even as generation fell nearly three percent.

In both countries, "many of the provinces and states leading coal development are major coal-producing regions", said Christine Shearer, project manager of GEM's Global Coal Plant Tracker and author of the report.

They have "strong industrial incentives to keep building coal", she told AFP.

- US actively increases coal -

China is the world's top emitter, while India ranks third behind the United States.

Beijing sees coal as a reliable failsafe for intermittent renewable supply, particularly for after power shortages several years ago.

India, the world's most populous country, is leaning heavily on coal to meet soaring electricity demand.

But coal's persistence is also the result of infrastructure issues.

Non-fossil fuels already account for 50 percent of India's installed capacity, but infrastructure and other issues mean the country still generates around three-quarters of its electricity from coal.

Globally, the retirement of coal power also slowed last year, with nearly 70 percent of units that were due to end operations instead staying online, GEM said.

In Europe, those missed targets were linked primarily to decisions taken during the 2022-23 energy crisis caused by Russia's invasion of Ukraine.

In the United States however, retirement delays were due to a government push for coal, said Shearer.

"US coal-fired generation rose by more than 80 TWh (terawatt hours) year-on-year, a figure so large that no other country came close," she said.

The surge "was not simply a function of (demand) growth, it reflected a policy environment that actively encouraged it," she added.

- Coal 'favouritism' -

The energy crisis sparked by the US-Israeli war with Iran has seen some countries turn back to coal, reactivating idle coal units or delaying retirements.

In China, coal-fired power generation also jumped in the first part of the year, in part due to "underperformance" by wind and nuclear.

"But the oversupply and favouritism of coal power is an important factor," added Lauri Myllyvirta, co-founder of the Centre for Research on Energy and Clean Air, and contributor to the report.

While figures from May suggest China's coal generation may have dropped again, "the problem of excess coal capacity and entrenched favouritism of coal in the grid remain", he told AFP.

Globally, coal-fired generation has risen 0.3 percent so far this year, Shearer said, while wind and solar generation has jumped 10 percent.

"Clean energy is absorbing most of the world's new electricity demand, with coal barely growing at all," she said.
