New report: China now generates 54 percent of the world’s coal-fired electricity

Coal-fired power’s generation and carbon-intensity are both falling somewhat around the world, but China has emerged far and away as the dominant driver in its rising relevance for the developing world.

A new Global Electricity Review by climate and energy think tank Ember released Monday estimated that global coal-fired electricity fell a record 4 percent in 2020 compared to the previous year. This fall was matched by a same level rise in wind and solar capacity (totaling more than 314 terawatt hours (TWh) in output).

In China, however, coal-fired power gained 2 percent in 2020. Worldwide, China now accounts for 53 percent of the overall coal-fired generation portfolio.

Pressure to meet increasing economic growth and customer need for electricity surely is pushing the Chinese coal-fired capacity forward, according to Ember. The nation’s total electricity demand has climbed more than 1,880 TWh in the past five years.

Ember concluded that global emissions are still higher than in 2015. Coal generation has fallen less than 1 percent since 2015, as developed nation rejection and Chinese capacity growth combat each other, but also gas-fired generation has risen 11 percent.

China is hardly neglecting renewables, though, as its wind and solar portfolio supplies 10 percent of the generation mix. This is in line with the worldwide percentage of wind and solar and also has taken 6 percent in market share from coal since 2015, the Ember summary noted.

“The expansion of renewable generation (821 TWh) in China, though impressive, could not meet its significant electricity demand growth,” the Ember report summary reads. “In order to maintain the sufficiency of electricity supply, coal also had to rise, supplying 39 percent of China’s electricity demand growth (734 TWh out of 1,884 TWh).”

In the world’s other major developing mega market, India, wind and solar generation have tripled in the past five years, according to Ember’s report. Coal fell 4 percent in India for 2020, partially suppressed by lower electricity demand during the COVID-19 pandemic and also due to 119 TWh in total generation of wind and solar last year.

India is dealing with the same upward market pressures as China, with electricity demand rising 18 percent since 2015. Carbon-free power met more than half of this demand, while fossil and mostly coal accounted 43 percent of the new-growth generation, according to Ember.

The United States has cut coal-fired generation by 43 percent since 2015 but is responsible for more than half of the global rise in gas-fired power since then. Natural gas as fuel for electricity has increased by 576 TWh in the past five years, with the U.S. supplying nearly half, or 283 TWh, of that rise.

“Coal was already in terminal decline in the United States, and this trend only accelerated in 2020. But the switch to fossil gas seen over the last decade has limited potential reductions in emissions, especially considering the harmful impacts of methane leakage from gas infrastructure,” Euan Graham, Ember’s electricity tracking analyst, said in the report. “President Biden’s clean power plan puts gas generation in the spotlight.

Thus, fossil generation has only really fallen by 11 percent since 2015. The U.S. and the world nearly match up with fossil fuels generating little more than 60 percent of the power mix.

Wind and solar rose by 42 TWh and 26 TWh, respectively, in 2020. These are both year-over-year record increases for either resource in the generation mix nationwide.

Ember’s report utilizes a global dataset for electricity generation and demand across 217 countries since 2000. The 2020 data includes 90 percent of the world’s electricity production.
