Introduction: The Secret Behind 5%
When China announced achieving 5.0% GDP growth in 2025 this January, many experts were puzzled. The real estate market remained in the doldrums, consumption was sluggish, and deflation concerns persisted. How was such growth possible under these circumstances?
A report released on February 5th by the Helsinki-based Centre for Research on Energy and Clean Air (CREA) provides the answer. Without the clean energy industry, China's 2025 GDP growth would have been just 3.5%, not 5.0%. In other words, China met its official growth target entirely thanks to clean energy.
This report contains crucial data revealing structural changes in China's economy. Let's analyze the new growth engine China discovered after the real estate bubble burst, and its implications for the global economy and energy markets.
Chapter 1: An Industry the Size of Brazil's Economy
In 2025, China's clean energy industry generated 15.4 trillion yuan (approximately $2.1 trillion) in economic value. This represents 11.4% of China's GDP, up more than 4 percentage points from 7.3% in 2022 in just three years.
Comparing this to other countries makes the scale clearer. The 15.4 trillion yuan is equivalent to the GDP of Brazil or Canada. If China's clean energy industry were an independent nation, it would rank as the world's 8th largest economy—about half the size of India's economy or similar to the US state of California.
What's even more remarkable is the growth rate. The real value of the clean energy industry, which was 8.4 trillion yuan in 2022, nearly doubled by 2025. The annual growth rate accelerated from 12% in 2024 to 18% in 2025. While China's overall economy grew at 5%, the clean energy sector expanded by 18%.
The concentration in investment terms is even more dramatic. Over 90% of China's total investment growth in 2025 came from clean energy. Clean energy investment reached 7.2 trillion yuan (approximately $1 trillion)—roughly four times the $260 billion invested in fossil fuel extraction and coal power generation.
Chapter 2: Filling the Void Left by Real Estate
To understand these numbers, we need to examine China's recent economic history.
Before 2020, real estate and related industries accounted for 25-30% of China's GDP. Including construction, steel, cement, furniture, and home appliances, the proportion was even higher. More than 40% of local government revenue depended on land sales. Real estate wasn't just an industry—it was the heart of China's economy.
Things began to change in 2020 when the Xi Jinping government implemented the "Three Red Lines" policy, restricting property developers' debt levels. Major developers like Evergrande and Country Garden fell into default one after another, and real estate prices and transaction volumes plummeted. By 2024, real estate's contribution to GDP had fallen by almost half from its peak.
Simultaneously, China needed to find new growth engines. The answer came in what's called the "New Three"—electric vehicles, batteries, and solar power. In 2023, these three product categories overtook clothing, furniture, and home appliances in China's export rankings for the first time.
According to the CREA report, EVs and batteries alone accounted for 44% of clean energy's economic contribution in 2025. Solar-related industries added 19%, while wind, nuclear, and hydropower contributed another 15%. Clean energy is filling the vacuum left by real estate.
Chapter 3: The Scale of the EV Revolution
China's electric vehicle market growth has been phenomenal.
In 2025, China produced 16.6 million electric vehicles (including battery EVs and plug-in hybrids), a 29% increase year-over-year. EVs accounted for 48% of all new car sales, exceeding 50% in the passenger car segment. In November 2025, EV sales surpassed 60% of total sales.
Just five years ago in 2020, EVs comprised less than 2% of vehicles on Chinese roads. By the end of 2025, this reached 12%—a sixfold increase. The electric truck market also surged, with market share jumping from 8% in 2024 to 23% in 2025, nearly tripling.
Investment in EV manufacturing facilities reached 1.6 trillion yuan ($228 billion), an 18% year-over-year increase. Charging infrastructure investment also jumped 58%, and the Chinese government announced plans to nearly double charging infrastructure over the next three years.
An interesting point is the price trend. While solar panel and battery prices continued to fall, average EV prices slightly increased in 2025. In a deflationary environment where China's overall Producer Price Index (PPI) fell 2.6%, EVs alone maintained their prices. This means the EV industry's contribution to nominal GDP growth was even more significant than its real contribution.
Exports also surged. In 2025, China exported 3.4 million EVs, an 86% year-over-year increase. Major export markets included Western Europe, the Middle East, and Latin America. Battery export value also grew 41% to 724 billion yuan, making it the third-largest contributor to GDP growth.
Chapter 4: The Shadow Over Solar
However, not everything is smooth sailing. The "overcapacity" problem in the solar industry is severe.
As of the end of 2025, China's solar manufacturing capacity reached approximately 1,200GW annually. The problem is that global solar installations for the same year were only about 650GW. China alone can produce nearly twice the world's demand.
The result is price collapse and profit erosion. Chinese solar companies are suffering from "historically low profitability," to the point where the government has warned against "irrational" price competition. President Xi Jinping himself has expressed concern about "involution" (intensifying internal competition).
Solar manufacturing facility investment fell 23% year-over-year to 506 billion yuan in 2025. This reflects government policies to curb overcapacity. However, solar power plant installation investment increased 15% to 1.18 trillion yuan, and China set another record by installing 315GW of solar and 119GW of wind capacity. More than half of global solar installations and more than double wind installations occurred in China.
The question is what happens from 2026 onwards. Under new pricing policies, new solar and wind generation must compete on price against existing coal power. In an environment where electricity market systems are not yet fully established, this increases investment uncertainty. Forecasts suggest that the 15th Five-Year Plan targets from the central government will be set far below the recent expansion rate, adding to concerns.
Chapter 5: A New Front in the US-China Trade War
The rise of China's clean energy industry has significant implications for US-China relations.
The Trump administration imposed 100% tariffs on Chinese EVs and 25% on batteries starting in 2025. The European Union is also considering additional tariffs of up to 45% on Chinese EVs. The US has also strengthened regulations on Chinese solar panels, semiconductors, and critical minerals.
However, the impact of tariffs on China's clean energy industry has been more limited than expected. According to the CREA report, 79% of Chinese EVs are still sold domestically, with exports accounting for only 21%. The domestic market is large enough to absorb the impact of export restrictions.
More importantly, there's supply chain dominance. China holds 60-80% market share in processing battery materials like lithium and cobalt. For solar polysilicon and wafers, it exceeds 90%. Even if the US raises tariffs, finding alternative suppliers isn't easy.
Meanwhile, China is responding to supply chain diversification. In 2025, solar cell and wafer exports increased 94% and 52% respectively, while finished panel exports grew only 4%. As other countries build panel assembly plants, intermediate goods exports are increasing. The export structure is shifting from final products to intermediate goods.
Chapter 6: Scenario Analysis — Will the Clean Energy Boom Continue?
Scenario A: Continued Growth (Probability: 50%)
Rationale:
- Historical precedent: Clean energy industry maintained 15%+ average annual growth from 2022-2025
- Local governments and state-owned enterprises announcing more aggressive investment plans than central government targets
- Policy support for alternative growth engines likely to continue as long as real estate slump persists
- Emergence of new growth areas such as electric trucks
Trigger Conditions:
- 15th Five-Year Plan sets clean energy targets above market expectations
- Power market reforms proceed favorably for renewables
- Real estate recovery delays, maintaining need for alternative growth engines
Timeframe: 12-15% average annual growth from 2026-2030
Scenario B: Growth Slowdown (Probability: 35%)
Rationale:
- New pricing policies deteriorate solar/wind investment profitability
- Corporate bankruptcies and restructuring due to overcapacity
- Export growth limited by Western tariff barriers
- If domestic consumption recovery is slow, EV sales may decelerate
Trigger Conditions:
- 15th Five-Year Plan targets set significantly below recent expansion rate
- Large-scale bankruptcy of major clean energy companies
- Additional tariff increases from US and Europe
Timeframe: Growth rate slows to 8-10% in 2026-2027 before stabilizing
Scenario C: GDP Drag (Probability: 15%)
Rationale:
- Overcapacity problem persists and spreads across the entire industry
- Corporate bankruptcies transmit to the financial system
- Export plummets due to trade war escalation
- Policy support shifts to other sectors
Trigger Conditions:
- Chain defaults of major clean energy companies
- US complete import ban on Chinese batteries and materials
- Chinese government prioritizes stimulus in other sectors over clean energy
Timeframe: Clean energy sector becomes a negative contributor to GDP growth after 2027
Chapter 7: Investment Implications
Positive Factors
The scale and growth trajectory of China's clean energy industry presents several investment opportunities.
First, the EV supply chain. The explosive growth of China's EV market is driving demand for related components and materials. Demand for battery materials (lithium, nickel, cobalt), semiconductors, and power electronics will increase.
Second, energy storage. Investment in grid-connected battery storage surged 52% in 2025. As renewable energy share increases, demand for storage technologies to address intermittency will grow.
Third, power grid infrastructure. Transmission and distribution network investment is essential for clean energy expansion. China's transmission grid investment reached 644 billion yuan in 2025, up 6%.
Risk Factors
At the same time, there are risks to watch.
First, the overcapacity problem. Supply glut is particularly severe in the solar sector. Chinese solar company share prices have fallen 60-80% from their 2023 peaks. Further declines are possible until restructuring is complete.
Second, policy uncertainty. The investment environment could change dramatically depending on new pricing policies and 15th Five-Year Plan targets.
Third, geopolitical risks. If the US-China trade war escalates, Chinese clean energy companies' overseas operations and supply chains will inevitably suffer.
Conclusion: A Massive Bet
China is making the largest energy transition bet in world history. In 2025 alone, it invested $1 trillion in clean energy, resulting in the clean energy industry accounting for 11.4% of GDP.
If this bet succeeds, China will lead the global energy transition while building a new economic growth model. It means transitioning the economic structure from real estate dependence to technology-based industries.
If it fails, there will be economic losses from overcapacity and resource waste. Signs are already visible in the solar industry.
What's certain is that China's clean energy industry has become "too big to ignore." An industry the size of Brazil's economy is growing at 18% annually. Its impact on the global economy, energy markets, and climate change cannot be overstated.
