In a groundbreaking development for renewable energy, China is poised to surpass coal in solar power capacity by the end of this year, marking a pivotal moment in the country’s quest for a sustainable energy future. According to a recent report from a prominent nonprofit, this remarkable transition highlights China’s rapid progress as the world’s largest solar market, despite its ongoing reliance on coal for energy security.
A New Era in Energy Capacity
By the close of 2026, wind and solar energy are projected to account for nearly half of China’s total installed power capacity, while coal’s share is expected to diminish to approximately one-third, as detailed by the China Electricity Council. This shift, while significant, does not imply that solar energy will immediately outproduce coal. The installed capacity reflects potential output under optimal conditions, and it is important to note that coal plants provide a more stable power supply than solar, which depends heavily on sunlight and weather conditions.
Andreas Sieber, political strategy head at the environmental organisation 350.org, described this shift as a “historic inflection point,” emphasising that it demonstrates the triumph of clean energy in terms of cost, scalability, and air quality improvement. Nonetheless, he cautioned that the continued expansion of coal complicates China’s energy politics, which may seem “impressive but schizophrenic.”
The Reality Behind the Numbers
It is crucial to approach the reported capacity crossover with a discerning eye. Lauri Myllyvirta, an energy analyst at the Centre for Research on Energy and Clean Air, expressed that while the development is symbolically significant, it does not necessarily reflect a practical shift away from coal. With solar energy’s average capacity factor hovering around 14 per cent compared to coal’s 50 per cent, the latter still generates roughly 3.5 times more electricity than solar.
However, the growth rate of solar and wind energy is outpacing total power demand, leading to a reduction in carbon emissions from fossil fuels. By the end of 2025, China’s solar capacity had reached about 1,200 gigawatts, with an impressive average increase of approximately 270 gigawatts per year over the past three years. Conversely, coal capacity is projected to hit around 1,333 gigawatts by the end of 2026, while total generating capacity across all energy sources is expected to rise by more than 400 gigawatts this year, aligning with increasing electricity demand.
Coal’s Continued Presence
Despite the rapid advancements in renewable energy, China is still adding coal capacity at an unsettling rate. In 2025 alone, 78 gigawatts of new coal power were brought online, a decision influenced by previous power shortages and rolling blackouts in 2021 and 2022 that raised concerns about energy reliability. Biqing Yang, an energy analyst for Ember, pointed out that coal’s role is evolving, transitioning from a primary electricity provider to a more flexible source that can support the energy grid during fluctuations in renewable energy output.
Yet, this dual approach raises alarms. Critics argue that the construction of new coal plants, justified as backup energy sources, risks becoming a long-term dependency that could undermine emission reduction efforts. With nearly 290 gigawatts of coal capacity either permitted or under construction—far exceeding what is necessary for China’s 2030 climate commitments—there are worries that these projects could entrench an outdated energy model.
The Road Ahead
Official forecasts suggest that coal’s share within China’s energy mix will continue to decline, with total installed capacity expected to reach around 4.3 billion kilowatts by the end of 2026. Non-fossil energy sources are projected to comprise roughly 63 per cent of this total, while coal’s share will fall to about 31 per cent.
Beijing now faces a crucial decision: to curtail its coal pipeline and facilitate a smooth transition to cleaner energy or to continue investing in coal assets that may hinder the progress already made in renewable energy. As Sieber aptly stated, the choice is stark—either embrace a cleaner future or become mired in costly, unnecessary infrastructure that could complicate the transition ahead.
Why it Matters
This landmark shift in China’s energy landscape is not just a national concern; it has profound implications for global climate goals. As the world’s largest emitter of greenhouse gases, China’s transition from coal to renewable energy sources will play a pivotal role in determining the future of global climate policy. The choices made today will resonate for generations, affecting energy security, environmental health, and the fight against climate change on a planetary scale. The world watches closely as China navigates this complex energy transformation.
