China Built the World's Green Energy Factory. Here’s How.

A massive domestic market allowed China to construct the industrial backbone of the global energy transition, according to a new analysis. The country’s rapid scale-up in manufacturing solar panels, wind turbines, and batteries has driven down costs worldwide. This growth is now a primary force in global climate action, writes Muri Yang, an analyst at energy think tank Ember. Yang specializes in China’s power sector. She states that consistent government policy and huge local demand created a "green momentum." This environment let companies experiment, improve technologies, and achieve large-scale production. The process is known as "learning-by-doing." It reduces prices through manufacturing experience and volume. As a result, China now dominates the supply chains for clean energy technologies. Many countries rely on Chinese exports for their own climate projects. This industrial capacity makes China a central player in international efforts to move away from fossil fuels. The scale of its production continues to shape the pace and affordability of the global energy shift.
