China burns more coal despite record renewables — here's why
China's CO2 emissions from energy and industry rose roughly 2% in the first quarter of 2026 — even as the country added record amounts of solar and wind capacity. The culprit isn't a shortage of clean power. It's a policy structure that locks coal plants into guaranteed output volumes, forcing them to run whether the grid needs them or not.
The contract trap
China's coal and gas plants operate under long-term contracts that promise specific generation volumes. When solar and wind flood the grid with cheap electricity, those plants keep running anyway — the contracts give operators no financial reason to cut output. The result, per Climate Change News citing CREA lead analyst Lauri Myllyvirta, is a grid that actively wastes clean energy rather than displacing fossil fuels.
A second layer of the problem sits between provinces. Electricity trading across regional boundaries is governed by annual contracts, not real-time pricing. So when one province has surplus wind power, it can't easily sell it to a neighbor — the contractual plumbing simply isn't built for that flow.
The numbers
The scale of waste is striking. Solar curtailment — clean energy generated but deliberately discarded — hit 9.2% in Q1 2026. Wind curtailment reached 8.5%. Had those rates stayed flat, China could have added around 170 TWh of renewable generation in the quarter. Actual growth was just 60 TWh. The 110 TWh gap, according to Carbon Brief, is roughly equal to France's total electricity consumption for a full quarter.
That's not an abstract statistic. It's clean power that existed, was generated, and was thrown away — while coal plants burned fuel to fill the same demand.
Why this matters beyond China
The Strait of Hormuz crisis earlier this year exposed how this grid rigidity creates an energy security problem, not just a climate one. A country with the world's largest renewable fleet still found itself exposed to fossil-fuel shocks because the system can't route cheap local power efficiently.
For US and UK grid operators, the lesson is direct: adding capacity solves only half the problem. Without flexible dispatch rules and short-term electricity markets, new wind and solar capacity can pile up while old fossil contracts quietly run in parallel. China is the largest-scale test of what happens when those reforms lag behind the build-out — and the Q1 2026 data suggests the gap is widening, not closing.
