Abstract: New quality productive forces, characterized by high technology, high efficiency, and high quality, impose new requirements on renewable energy legislation, including strengthening institutional support for scientific and technological innovation, enriching the normative expression of energy conservation and carbon reduction, and improving the supply of regulatory frameworks. Although China’s renewable energy legislative system has been largely established, there remain prominent issues such as the absence of special legislation in key areas, conflicts among relevant laws, and obsolescence of certain institutional provisions, which collectively hinder the effective responsiveness to the legal demands arising from the development of new quality productive forces in the energy sector. To promote the high-quality development of the renewable energy industry, the improvement of renewable energy legislation should proceed along two dimensions: perfecting the legal normative system and refining institutional articulation. At the systemic level, efforts should be made to advance special legislation for key sectors such as solar, wind, and hydrogen energy, and to harmonize the relationships among the Renewable Energy Law, the Energy Law, and the Electric Power Law. At the institutional level, it is necessary to establish a renewable portfolio standard and a green electricity certificate system, improve market-based incentive mechanisms and policy guidance mechanisms for scientific and technological innovation, and update the renewable energy development fund system and the full-guaranteed purchase system. Only through systematic legislative responses can a solid rule-of-law guarantee be provided for the energy green transition under the guidance of new quality productive forces.
