China Generates Less Than Half of Its Electricity From Coal for First Time

A Historic Shift in the World's Largest Power Grid

China's power sector reached a milestone earlier this year: for the first time in recorded history, coal generated less than half of the country's electricity. According to data compiled by energy analysts and industry groups, the share of coal-fired generation fell below the 50 percent mark during the opening months of 2025, ending a decades-long era in which the fuel was the undisputed backbone of the world's second-largest economy.

The figure represents a dramatic structural shift. As recently as five years ago, coal accounted for roughly 62 percent of China's electricity generation. In 2024, the share had declined to just above half before breaking beneath the psychological and statistical threshold this year. The decline is all the more striking given that total electricity generation in China continues to rise.

"This is a genuine watershed," said a senior energy analyst at a Beijing-based research institute. "Coal is no longer the majority fuel in China's electricity mix. That does not mean the coal industry is collapsing — but it does mean the long-term trajectory is finally, firmly pointing downward."

Water, Wind, and Sun: What Replaced the Coal?

The most immediate cause of the shift was an extraordinary rebound in hydropower. China's vast cascade of dams along the Yangtze and other river basins — including the world's largest hydropower station, the Three Gorges Dam — saw reservoir levels and generation recover strongly after several drought-affected years. Hydroelectric output rose by more than 20 percent year-on-year in the early part of 2025, flooding the grid with cheap, zero-carbon electricity.

Solar and wind power also continued their astonishing expansion. China installed more solar capacity in 2024 alone than the entire solar fleets of the United States and Europe combined, and wind additions set new records as well. Although the sheer scale of installations sometimes outpaces grid integration, the growing generation from these sources has directly displaced thermal power, particularly during daytime and windy periods.

At the same time, electricity demand growth slowed. China's property sector remains weak, and energy-intensive sectors such as steel and cement have reduced output. Power demand rose roughly 5 percent in 2024, but the pattern has been uneven, with industrial consumption lagging earlier forecasts.

The combination was decisive. When demand grows slowly, cheap low-carbon electricity floods the system, and coal plants — which are generally dispatched last because of marginal fuel costs — are pushed out of the merit order.

A Qualified Milestone: Coal Capacity Still Expanding

Yet the news carries important caveats. China's coal fleet is not shrinking; it is still expanding, albeit more slowly. Beijing continues to approve new coal power capacity, largely as a reliability backstop and to support the integration of intermittent renewables. The fleet's utilization rate — how often and how hard plants run — has fallen to record lows, indicating that many new plants are being built to sit idle for much of the year.

"The distinction between coal capacity and coal generation is the whole story here," an energy economist at a major international university noted. "China made a strategic choice: build more coal plants as insurance against grid instability, but run them less. That preserves the coal industry's social and political position while allowing the clean energy transition to move much faster than most outsiders realize."

This has important consequences for global emissions. Because coal generation is what determines carbon dioxide output from the power sector, a declining share means emissions from Chinese electricity generation are likely plateauing — even if China's installed coal capacity continues to grow.

The Volatility Problem: Weather Can Still Swing the Numbers

While the headline numbers point decisively in a non-coal direction, the transition is still subject to considerable turbulence. In 2022, when a severe drought crippled hydropower output and the government imposed widespread restrictions during heatwaves, coal-fired generation actually rose to record highs to compensate. Analysts caution that such weather-driven swings will continue: a dry year could push coal's share back above half, while a wet year will push it further down.

"One year's statistics don't constitute a trendline, but the underlying here is a very real trend," one independent energy analyst said. "Hydropower will vary, but wind and solar are non-negotiable: their installation rates are so far ahead of schedule that no amount of bad weather can offset their growth for long."

Grid operators have responded with a suite of measures to manage renewable variability, including ambitious energy storage targets. China is on track to install hundreds of gigawatt-hours of battery storage, and pumped-hydro storage projects are being developed at an unprecedented clip. In some provinces, renewable curtailment has become an issue of its own, as supply outpaces transmission capacity.

Implications for Coal Miners and the Global Market

The shift is also reshaping China's coal economy. Domestic thermal coal prices have been under pressure as power plants reduce their fuel purchases, squeezing mining provinces in the north that heavily depend on the industry. The government has taken steps to stabilize the market, asking state-owned coal firms to maintain output levels and shoring up the utilities' ability to stockpile. But many miners are already diversifying.

"It's a painful adjustment," an economist specializing in China's energy provinces said. "Growing output from renewables, an aging population, and slower industrial growth mean coal demand has reached a structural ceiling. Communities dependent on coal mining are going to need a decade-long transition plan."

Internationally, China's reduced appetite for seaborne coal has had mixed effects. Imports were still high in 2024 and early 2025, largely because domestic production was constrained after a series of mining accidents and regulatory inspections. But over a multi-year horizon, the trend is unmistakable: China's structural coal demand is falling, and global coal exporters — from Indonesia to Russia to Australia — are likely to face increasingly challenging market conditions.

What Comes Next: Peak Emissions, Grid Hardening, or Backlash?

The power sector tells only part of China's emission story. Coal continues to be used directly in heavy industries such as steelmaking, cement kilns, and chemical plants, often burned on-site rather than drawn from the grid. China's overall coal consumption may therefore remain elevated even as power generation grows greener.

Still, the electricity milestone is the most important single indicator for near-term emissions. With China accounting for roughly 30 percent of global carbon emissions, and coal electricity being its largest source, the crossing of the 50 percent line raises hopes that Chinese emissions have reached their peak. Recent data suggests that the country's overall emissions may indeed have plateaued in 2024 — earlier than many models predicted a decade ago.

The chief test ahead is grid resilience. Every large step toward renewables brings new stress: voltage stability, frequency control, and the challenge of moving electricity from the sunny, windy west to the high-demand eastern coast. China's answer has been massive investment in ultra-high-voltage transmission lines, which some experts criticize as overbuilt, and battery storage, which most agree remains the key enabler.

"China is building the energy system of the future, but it is doing so on a scale and at a speed for which there is no template," an energy policy analyst noted. "The next five years will reveal whether such a rapid structural shift can be sustained — and what its cost will be."

A New Political Arithmetic

There is also a political dimension. Chinese leaders have long made coal a strategic priority, and the State Council has repeatedly stressed the importance of cheap and secure power supply. Below 50 percent, coal's role will be re-framed not as the economy's engine but as a strategic reserve — a role Beijing has explicitly assigned to it in recent five-year plan discussions.

That re-framing, some suggest, may actually accelerate the transition. Once coal is officially positioned as a backup technology, investment logic tilts even further toward renewables, storage, and transmission. If the share holds through the rest of 2025, the milestone will likely be treated not as an anomaly, but as the new norm.

For now, the energy world is parsing the numbers with deep interest. China is responsible for a third of global carbon emissions, and its coal consumption impacts everything from global commodity prices to geopolitical alliances. That a country of 1.4 billion people can, in a few short years, redefine the energy foundation of its economy is a development whose ripple effects will be measured for decades.

"Every industry, every household, every policy maker in the energy world will need to re-examine their baseline assumptions," one veteran China energy expert concluded. "The idea that China is locked into coal for the foreseeable future — as it was widely assumed to be — is now gone. That changes many bets."
