新能源算清“发电账”，风能太阳能资源丰富区都在哪？

Core Insights - The China Meteorological Administration released the "2025 China Wind and Solar Resource Annual Report," indicating a normal wind resource year and a slightly below-average solar resource year for 2025 [1] Wind Energy Resources - The average annual wind speed at 100 meters is approximately 4.8 meters per second, while at 140 meters it is about 5.1 meters per second, with regions like North China, Northeast, and Northwest having speeds exceeding 6.0 meters per second, indicating rich wind energy resources [1] - Offshore areas show even higher potential, with average wind speeds of 7.8 meters per second at 100 meters and 8.0 meters per second at 140 meters [1] Solar Energy Resources - The total annual solar radiation is projected to be 1495.7 kilowatt-hours per square meter, which is 25.1 kilowatt-hours per square meter lower than the average of the past 30 years, categorizing it as a below-average year for solar resources [1] - The Tibetan Plateau, western Inner Mongolia, and eastern Xinjiang are identified as the richest solar resource areas, with radiation exceeding 1750 kilowatt-hours per square meter [2] Innovations in Data and Assessment - The report features innovative foundational data, utilizing high-precision monitoring datasets developed by meteorological departments, which surpasses the accuracy of foreign products [3] - The assessment aligns with current trends in the renewable energy sector, focusing on wind turbine hub heights of around 140 meters and providing detailed solar resource evaluations for photovoltaic systems [3] Enhanced Resource Analysis - The report includes a comprehensive analysis of offshore wind resources and specific assessments for large-scale renewable energy bases, aiding in planning and operational decisions [4]
