China’s combined wind and solar capacity exceeded its thermal power capacity for the first time in 2025, a milestone that would seem to signal a decisive shift away from fossil fuels. Yet the country simultaneously pushed coal production to a record 4.83 billion tons that same year, while fielding a record number of proposals for new coal-fired power plants. That contradiction sits at the heart of Beijing’s energy strategy: green capacity is growing fast, but coal remains deeply embedded in the system and shows no sign of disappearing.
Record Renewables, Record Coal
The numbers on the clean energy side are genuinely striking. Renewables now account for over 60% of China’s total power capacity as of 2025, according to National Energy Administration data published through the State Council. Newly installed wind and solar capacity increased 22% in 2025, hitting record highs. China crossed the 1 TW threshold for solar PV capacity alone, a figure that dwarfs the entire installed generation fleet of most countries.
But capacity is not the same as generation. Coal-fired plants run far more hours per year than wind turbines or solar panels, which produce power only when conditions allow. So while renewables dominate the capacity ledger, coal still supplies a disproportionate share of the electrons that actually flow through the grid. The International Energy Agency’s mid-year analysis found that coal-fired generation in China declined in the first half of 2025, which is encouraging. That decline, though, started from such a high baseline that coal remains the single largest source of electricity in the country by a wide margin.
On the supply side, coal mining has surged in parallel. Official statistics from the National Bureau of Statistics show that raw coal output climbed again in 2023, reinforcing the trend toward record production levels. The combination of expanding renewables and rising coal output underscores how China is pursuing an “additive” energy strategy: building new clean capacity without yet retiring significant amounts of fossil fuel infrastructure.
Why Coal Construction Keeps Accelerating
If renewables are growing so fast, why is China still building coal plants at a pace not seen in nearly a decade? Construction began on 94.5 GW of new coal power plants in 2024, the highest level in roughly ten years, based on a Global Energy Monitor database review. And in 2025, China fielded a record number of proposals for additional coal-fired capacity even as coal usage dipped.
The standard explanation from Chinese energy planners centers on grid reliability. Wind and solar output fluctuates with weather, and China’s grid, which spans vast distances and serves over a billion people, has experienced power shortages before. Thermal coal prices nearly tripled during the 2021 energy crunch, according to contemporary market reporting, and that crisis left a lasting mark on policy. Provincial governments, which approve many coal projects, treat new thermal plants as insurance against blackouts. The result is a system where energy security concerns at the local level override national decarbonization ambitions.
There is also a structural incentive problem. Coal plant approvals are often driven by provincial economic interests: construction jobs, tax revenue, and guaranteed power supply for industrial zones. Once permitted, these plants have lifespans of 30 to 40 years, locking in emissions for decades regardless of how much solar capacity is added alongside them. Researchers assembling a comprehensive inventory of Chinese coal power have highlighted how existing and planned units create a long tail of future emissions unless retirements accelerate significantly.
The Gap Between Capacity and Consumption
A common misreading of China’s energy data confuses installed capacity with actual energy consumed. Renewables crossing the 60% capacity mark is a real achievement, but it does not mean 60% of China’s electricity comes from clean sources. Wind and solar capacity factors, the share of time a plant actually generates power, typically range between 15% and 30%, depending on location and technology. Coal plants, by contrast, can run around the clock.
This gap helps explain why China’s coal consumption reached 4,883 million tons in 2023, an increase of 276 Mt over the prior year, according to the IEA’s coal demand assessment. Even with the first-half 2025 decline in coal-fired generation, the absolute volumes remain enormous. China’s coal output hit a record 4.83 billion tons in 2025, per National Bureau of Statistics data. The country is producing more coal than ever, even as it burns slightly less of it for power, suggesting that stockpiling and non-power industrial uses, such as steel and chemicals, continue to drive extraction.
At the same time, the rapid deployment of wind and solar is beginning to bend the curve. The IEA notes that renewable generation in China is now growing faster than electricity demand, which should gradually erode coal’s market share if current trends persist. But that erosion will be slow unless institutional and technical barriers that favor coal are addressed head-on.
Grid Bottlenecks Fuel the Paradox
Much of the tension between China’s green ambitions and its coal dependence traces back to physical grid constraints. Solar and wind farms are concentrated in the country’s north and west, far from the coastal manufacturing hubs where electricity demand is highest. Transmission infrastructure has not kept pace with renewable installations, meaning that clean power sometimes goes to waste while coal plants closer to demand centers keep running.
Inadequate flexibility compounds the problem. China’s power system still relies heavily on inflexible baseload units and has limited storage and demand-response capacity. Without more batteries, pumped hydro, and market mechanisms that reward shifting consumption to match renewable output, grid operators default to dispatching coal plants to maintain stability.
Academic research on China’s energy and climate paradox has long identified this disconnect between central targets and provincial execution. Local officials face competing mandates: meet renewable energy quotas while also guaranteeing uninterrupted power supply and economic growth. When those goals conflict, reliability wins. That dynamic makes coal plants attractive as “backup,” even if they end up running far more than strictly necessary.
Policy Signals and the Road Ahead
Beijing has tried to steer the system away from indiscriminate coal expansion without triggering fears of power shortages. Central authorities have tightened environmental and efficiency standards for new plants and emphasized that coal should increasingly play a “supporting” role, providing flexibility rather than baseload power. In practice, however, the line between support and expansion remains blurry.
Stronger enforcement of utilization limits could help. If new coal units were constrained to low operating hours and compensated mainly for capacity and flexibility, their climate impact would be smaller. Coupling those limits with accelerated investment in ultra-high-voltage transmission, large-scale storage, and more sophisticated power markets would make it easier to rely on renewables without sacrificing reliability.
Ultimately, China’s energy transition is unfolding on two tracks at once. On one track, record-breaking additions of wind and solar are pushing the power system toward a lower-carbon future. On the other, entrenched coal interests, institutional inertia, and legitimate concerns about energy security are slowing the pace of change. The coexistence of record renewables and record coal is not a contradiction so much as a snapshot of a system in flux, where old and new energy paradigms are still vying for dominance.
How quickly the balance tips will depend less on headline capacity numbers than on the gritty details of grid reform, provincial incentives, and plant-level operating rules. For now, coal remains the backbone of China’s power supply even as renewables race ahead in capacity terms. Bridging that gap, so that clean energy not only dominates the construction pipeline but also the actual flow of electrons, will determine whether China can align its energy system with its long-term climate goals.
