Renewable power has become the main force to promote global energy transformation towards low-carbon. Since the second half of 2023，tripling renewable power by 2030 has been proposed on many international events. However，it is great challenge for countries and regions，with different degrees，to keep high growth of renewable power from present to 2030. USA and Europe attempt to support local industrial chains to re-build global renewable production landscape，increasing the complexity of tripling renewable power. This paper explains the status of global renewable power development，summarizes the road proposed by some international organizations including IRENA to realize tripling renewable power by 2030，analyzes its matching degree with China’s goal of achieving the proportion of non-fossil energy，China’s possible role and contribution. The key point of tripling renewable power by 2030 is wind and solar power development，with challenges focusing on energy and power infrastructure and industry trade barriers to be overcome. Whether from promoting the realization of tripling renewable power by 2030，or domestic energy green low-carbon transformation，or supporting development of domestic healthy industries，China wind and solar power and other renewable energy markets need to continue to maintain a high scale. Power sources should be diversified，flexible resources should be reasonably allocated，and power grid should be improved. The policy mechanism should guarantee the market scale and investment of domestic renewable power projects，while reducing and solving the impact of international trade barriers，and promoting China’s manufacturing industry to contribute to the global tripling renewable power by 2030 as well as energy transformation.
