China generated 53% of the world's total coal-fired power in 2020, nine percentage points more that five years earlier, despite climate pledges and the building of hundreds of renewable energy plants, a global data study showed on Monday.
Although China added a record 71.7 gigawatts (GW) of wind power and 48.2 GW of solar last year, it was the only G20 nation to see a significant jump in coal-fired generation, according to research from Ember, a London-based energy and climate research group.
China's coal-fired generation rose by 1.7% or 77 terawatt-hours, enough to bring its share of total global coal power to 53%, up from 44% in 2015, the report showed.
The country has promised to reduce its dependence on coal in a bid to bring emissions of climate-warming greenhouse gas to a peak before 2030 and become "carbon neutral" by 2060.
"China is like a big ship, and it takes time to turn in another direction," said Muyi Yang, senior analyst with Ember and one of the report's authors.
China has so far been unable to find enough clean energy to meet rapid increases in electricity demand. Renewables met only around half of China's power consumption growth last year.
New coal-fired power installations reached 38.4 GW in 2020, more than three times the amount built by the rest of the world, according to a February research report.
China has steadily reduced the share of coal in total energy consumption from around 70% a decade ago to 56.8% last year. But absolute generation volumes still rose 19% over the 2016-2020 period, Ember calculated.
In its 2021-2025 five-year plan, China vowed to "rationally control the scale and pace of development in the construction of coal-fired power," and Yang said tougher measures could follow.
"I think there will be a cap on coal consumption, and that will have a major impact on the future trajectory for coal power," he said.
