For the first time since coal-fired generators began lighting cities in the early 1900s, renewable energy sources produced more of the world’s electricity than coal did. The crossover happened in 2025, according to data published by the International Energy Agency and the independent energy think tank Ember, and it was driven overwhelmingly by a solar building spree led by China.
The milestone, confirmed in reports released through early 2026, does not mean coal disappeared. It still fueled roughly a third of global power. But renewables, including solar, wind, and hydropower, collectively edged past it, marking a shift that energy analysts had forecast for years but that kept slipping just out of reach.
The numbers behind the crossover
The IEA laid the groundwork in its Renewables 2024 forecast, which explicitly predicted renewables-based generation would overtake coal-fired output the following year. That projection hinged on rapid solar deployment, continued wind buildout, and steady hydropower contributions across dozens of countries.
By the time the agency published its Global Energy Review 2026, the data bore out the call, though with a caveat. The IEA described renewables as having “virtually matched” coal rather than decisively surpassed it. Coal-fired generation slipped by roughly 0.5% globally in 2025, a figure the IEA presents as a preliminary estimate subject to revision as national statistics offices finalize their reporting. Meanwhile, renewable output continued to climb. It is worth noting that the IEA’s January 2025 Electricity Mid-Year Update had already shown the trend accelerating before the full-year data arrived. The agency’s underlying Global Energy Review Dataset, which covers world-aggregate electricity generation through 2025, provides the statistical backbone and is publicly downloadable for independent verification.
Ember’s own Global Electricity Review 2025 put a finer point on the result: renewables reached roughly 34% of global generation versus coal’s 33%. Ember characterized the moment as the first time in more than a century that coal lost its top position. No primary historical dataset covering year-by-year generation shares back to the early 1900s has been cited by either institution, so the “more than 100 years” framing rests on the conventional understanding that coal became the dominant electricity fuel in the early twentieth century rather than on a specific archival record. The gap between “virtually matched” and “clearly topped” is not just semantic. It reflects genuine differences in how the two institutions classify sources like small-scale hydro, biomass, and waste-to-energy plants. Either way, the directional story is the same: coal’s long dominance has ended or is ending.
China’s solar surge did the heavy lifting
No single factor mattered more than China’s extraordinary pace of solar installation. According to China’s National Energy Administration, the country added more than 200 gigawatts of solar capacity in 2024 alone, a figure larger than the entire installed solar fleet of any other nation. That momentum carried into 2025, and because China is also the world’s largest coal consumer, every gigawatt-hour of solar output there directly pressured coal’s global share.
Other regions contributed as well. The European Union continued retiring coal plants while expanding offshore wind. The United States saw solar and battery-storage projects accelerate under Inflation Reduction Act incentives. India, despite adding some new coal capacity, also broke its own records for solar installations. Brazil and parts of Southeast Asia added wind and solar at rates that would have been unthinkable a decade ago.
Underlying all of it is cost. The levelized cost of new solar generation has fallen below that of new coal plants in most major markets, according to BloombergNEF and Lazard analyses published in recent years. When building solar is cheaper than building coal, even countries with large domestic coal reserves face economic pressure to shift.
What the data does not yet show
Several important questions remain open. The IEA’s global totals rely partly on institutional estimates rather than finalized national statistics, particularly for China and India. Coal consumption patterns in those two countries alone could shift the global balance by a percentage point or more once their statistical agencies publish final 2025 electricity figures.
Emissions reductions tied to the crossover are also unquantified in the primary sources reviewed here. The logic is straightforward: displacing coal with wind and solar cuts carbon dioxide. But no specific tonnage of avoided emissions for 2025 has been published by either the IEA or Ember as of May 2026. Any such figure circulating in commentary should be treated as an estimate.
Equally unclear is how much of the renewable surge came from government policy versus pure market economics. Feed-in tariffs, tax credits, and renewable portfolio standards have all played roles, but the sources available do not break down their relative contributions. That gap matters for policymakers trying to replicate success: knowing that renewables rose is useful, but knowing which incentives delivered the most cost-effective deployment is far more actionable.
Coal is not gone, and the transition is not simple
Losing the top spot in generation share is not the same as disappearing. Coal still powers hundreds of millions of homes and factories, particularly across South and Southeast Asia. New coal plants continue to be built, even as older ones retire in Europe and North America. The Global Energy Monitor tracked more than 500 gigawatts of coal capacity in various stages of development worldwide as of late 2025.
For coal-dependent economies, the crossover raises hard questions about timing. Retiring aging plants too quickly risks blackouts and price spikes; keeping them running too long locks in emissions and strands capital. Workers and communities tied to coal mining and coal-fired power face disruption that clean-energy jobs do not automatically offset, at least not in the same places or on the same timeline.
Countries that moved early on renewables, such as Denmark, Portugal, and parts of Australia, are now stress-testing whether high shares of variable generation can coexist with reliable, affordable power. Grid-scale battery storage, demand response, and upgraded transmission lines are all part of the answer, but none of them are free or instant.
How the gap between coal and renewables may widen through 2026
Future data releases will sharpen the picture. As national statistics offices finalize their 2025 electricity balances and the IEA updates its global series later in 2026, the narrow gap between coal and renewables should resolve into a clearer lead for one side. Ember and other independent analysts will iterate their models as better numbers emerge.
The trajectory, though, is harder to dispute than the decimal point. Solar capacity is still being added faster than any other generation source in history. Wind is growing steadily. Battery costs continue to fall. Coal, meanwhile, faces tightening emissions regulations in Europe, carbon-pricing pressure in parts of Asia, and financing headwinds from banks and insurers increasingly reluctant to back new fossil-fuel projects.
None of that guarantees a smooth or fast transition. But the 2025 crossover, whether the final margin turns out to be one percentage point or a statistical tie, represents something that would have seemed implausible even a decade ago: a world in which the collective output of solar panels, wind turbines, and hydropower dams rivals the fuel that powered the industrial age.
