While Western nations spent years arguing over climate policy, China built the world's dominant green energy infrastructure. The gap between Western rhetoric and Chinese action has become impossible to ignore. At COP30 in Paris, delegates faced a stark reality: Beijing controls the solar panels, batteries, and wind turbines that will define the global energy transition. The disparity raises uncomfortable questions about whether democracies can match authoritarian speed and scale on climate. Western nations are now scrambling to catch up, but China's head start in manufacturing and deployment may prove decisive.
