Beyond solar panels: China's role in the global green transition

The global transition to cleaner energy is often discussed in terms of climate targets or geopolitical competition. Less attention is paid to the industrial systems that make that transition possible. China's solar photovoltaic (PV) industry offers a useful example. Over the past decade, China has expanded renewable energy at home while becoming the world's leading producer of solar technologies. The result has been felt far beyond its own borders. Greater manufacturing capacity has made solar power more widely available, supported new clean-energy industries and provided countries and regions with another pathway to diversify their energy supplies. At the same time, China's dominant position in global PV manufacturing has also raised legitimate questions about supply-chain concentration and resilience, making solar an increasingly important issue in both climate and energy-security discussions.

China's position in the industry did not emerge overnight. Solar PV has become one of the most mature and scalable clean-energy technologies, and China's role in that evolution has grown steadily over the past two decades. During the 14th Five-Year Plan period, the annual output value of China's PV manufacturing sector exceeded 1 trillion yuan (around $148 billion), while exports totaled more than $180 billion. The breadth of overseas demand is particularly notable. Chinese-made solar products are used in economies with very different development strategies and energy policies, suggesting that the industry's expansion reflects not only domestic industrial policy but also sustained international demand for affordable renewable-energy technologies.

The significance of this development extends well beyond solar panels themselves. China's investment across the PV supply chain has helped drive advances in batteries, energy storage, smart grids and electric vehicles, contributing to the world's largest renewable-energy system. As China's clean-energy technologies have expanded into overseas markets, it have also supported the development of renewable-energy industries in countries and regions such as Malaysia and Vietnam while encouraging investment in more flexible electricity grids. China's contribution also extends beyond the solar industry itself. In recent years, it has built the world's largest renewable-energy system, expanded the global reach of its electric-vehicle industry, and played a role in facilitating the Kunming-Montreal Global Biodiversity Framework. These developments reflect China's efforts to link its domestic green transition with broader international environmental cooperation.

There is also an important energy-security dimension. Countries and regions without significant oil and gas reserves have traditionally relied either on domestic coal or on imported fossil fuels to meet their energy needs. Solar power changes part of that equation. Although PV panels and other equipment may still be imported, the electricity itself is generated domestically. For countries and regions with abundant solar resources but limited fossil-fuel reserves, expanding solar generation can strengthen energy security by reducing reliance on volatile international fuel markets. While solar does not eliminate external dependence altogether, it reduces the need for continuous fuel imports by allowing countries and regions to generate more of their own electricity.

None of this means China's solar industry should be viewed without criticism. Manufacturing concentration, recycling, grid integration and the environmental footprint of production remain important challenges, and no single technology can deliver a secure and fully decarbonized energy system on its own. But these trade-offs should be considered alongside the industry's broader contribution. By lowering the cost and expanding the availability of solar technologies, China has helped make renewable electricity more accessible at a pivotal stage of the global energy transition. The significance of the solar industry development extends beyond its manufacturing scale and export performance. Its development has also expanded the practical options available to countries and regions seeking cleaner and more sustainable paths to development.
