China’s Renewable Boom Could Trigger Global Fossil Fuel Decline: A Tipping Point in Energy Transition

In 2025, China’s explosive growth in renewable energy has positioned it as the undisputed leader in the global clean energy revolution, with wind and solar generation surging 27% in the first half of the year and renewables overtaking coal in installed capacity for the first time. This boom, fueled by $625 billion in investments last year—31% of the global total—has led to a 2% decline in fossil fuel generation despite rising electricity demand, signaling the onset of a structural downturn in global fossil fuel use. Reports from Ember and Carbon Brief highlight China’s role in curbing coal output by 4% in Q1 2025 and emissions falling 1-1.6% year-on-year, creating conditions for worldwide fossil fuel demand to peak and decline. This article delves into the drivers of China’s renewable surge, its historical trajectory, future projections, and far-reaching impacts, with emphasis on India’s opportunities and Tamil Nadu’s pivotal position as a solar and EV manufacturing hub.

Why China’s Boom Matters

China’s dominance in clean tech—producing 80% of global solar panels and 75% of batteries—has slashed renewable costs by 80% since 2010, making them cheaper than fossil fuels in many markets. This shift not only secures China’s energy independence, reducing oil import reliance from 70% to under 50%, but also accelerates the global energy transition, potentially averting 10 gigatons of annual CO2 emissions by 2030. For India, pursuing 500 GW renewables by 2030, China’s exports of affordable tech offer a blueprint and supply chain, while Tamil Nadu’s Vikram Solar and Foxconn plants could export $5 billion in components, adding ₹10,000 crore to the state’s GDP and aligning with IMC 2025’s clean energy focus.

Latest Developments Driving the Boom

China’s 2025 renewable milestones underscore its structural shift from fossil fuels, with key advancements including:

• Record Capacity Additions: Solar and wind capacity doubled in three years, reaching 1,000 GW by mid-2025, surpassing coal. In Q1 2025, clean energy generated 951 TWh, with solar hitting a record 96 TWh in April—43% higher than 2024—while wind rose 16%.
• Fossil Fuel Decline: Coal-fired generation fell 4% to 1,421 TWh in Q1, with fossil share dropping from 63% to 58%; overall fossil output declined 2% in H1 2025 despite demand growth, marking the first sustained drop.
• Investment Surge: $625 billion in clean energy in 2024 (vs. $1.12 trillion global fossil investments), with battery storage up 69% and grid investments 22%. China accounts for 31% of global clean energy spending.
• Electrification and Exports: Fossil use in buildings, industry, and transport fell 1.7% from 2015-2023, while electricity use rose 65%; exports of solar panels and batteries to emerging markets like India enable “leapfrogging” fossil infrastructure.
• Policy Momentum: “Made in China 2025” and 14th Five-Year Plan mandate 1,200 GW solar/wind by 2030; rare earth restrictions secure supply chains.

Tamil Nadu’s Context

Tamil Nadu, with 10 GW solar capacity and Chennai’s EV hubs, benefits from China’s affordable imports, scaling Vikram Solar to 20 GW by 2030 and creating 50,000 jobs, while exporting panels amid global decline in fossil tech.

Historical Context of China’s Energy Shift

China’s renewable ascent began with economic pragmatism, evolving into a global force:

• 2000s: Oil crises spurred early solar/wind R&D; 11th Five-Year Plan (2006-2010) targeted 15% renewables.
• 2010s: “Made in China 2025” flooded markets with cheap solar (80% cost drop); capacity grew 12-fold, but coal peaked at 4,200 TWh in 2013.
• 2020: Pandemic accelerated EVs; renewables hit 29.4% of electricity, with solar/wind surpassing hydro.
• 2023: Emissions plateaued; coal share fell to 60%, with $940 billion clean investments.
• 2024-2025: Renewables overtook coal capacity; fossil generation declined 2-4%, emissions dropped 1.6% in Q1 2025.

Tamil Nadu’s solar journey, from 1 GW in 2015 to 10 GW, mirrors this, with PLI schemes attracting Chinese tech transfers.

Future Scopes and Projections

China’s boom projects renewables at 50% of global electricity by 2030, with fossil demand peaking in 2025-2026. Key forecasts:

• Capacity Growth: 1,200 GW solar/wind by 2030; battery storage triples to 1 TWh.
• Emissions Peak: CO2 falls 1-2% annually post-2025; global fossil demand declines 5% by 2030.
• Export Dominance: China supplies 80% of global clean tech, enabling emerging markets to leapfrog fossils.
• India Synergies: 500 GW renewables; Tamil Nadu exports $5 billion in panels/batteries.

Long-Term Strategic Outlook

By 2035, renewables dominate 70% of China’s power; global fossils decline 20%, with India at 50% renewables. Tamil Nadu could lead EV/solar exports, adding ₹20,000 crore. Challenges: Grid integration (curtailments at 5%), supply chain vulnerabilities, and US tariffs on Chinese tech.

Impacts on the Indian Economy and Stakeholders

China’s surge accelerates India’s transition, potentially saving $100 billion in fossil imports by 2030.
