Group 1 - Over 70% of China's oil energy relies on imports, posing a significant risk to national security during conflicts, especially if maritime transport routes are blocked by the US [1][3] - The urgency to develop alternative energy sources such as solar, wind, and hydropower is emphasized to reduce dependency on oil and enhance resilience against external pressures [3][5] - China's renewable energy sector has made notable progress, leading the world in photovoltaic capacity and wind power integration, but further efforts are needed across multiple fronts to achieve energy independence [5][11] Group 2 - A stable "new energy + storage" system is essential, as renewable energy sources like wind and solar are intermittent; exploring diverse storage solutions such as hydrogen and compressed air is recommended [5][9] - The construction of smart grids is critical, with projects like "source-network-load-storage" collaboration aiming to balance electricity supply and demand through advanced technologies [7][9] - The rapid growth of electric vehicles is driving advancements in battery technology, with companies like CATL developing sodium-ion batteries that do not rely on lithium resources, potentially reshaping the global energy supply chain [9][11] Group 3 - Historical context indicates that energy autonomy is achieved through innovation and breakthroughs, as seen in projects like the world's largest liquid air energy storage plant in Qinghai and successful methane hydrate extraction in the South China Sea [11] - The future competition among major powers will not only involve military and technological aspects but also the race to establish zero-carbon energy systems, with China's "green card" potentially being the key to overcoming oil dependency [11]
