美国伯克利实验室：2035年日本报告：太阳能、风能和储能成本的下降将加速日本清洁和独立的电力未来（英文版）

Japan faces a significant energy security risk as it imports nearly all of the fuel used in its power sector, with clean electricity accounting for only 24% of the total. This study shows that, due to the decreasing costs of solar, wind (especially offshore), and battery technology, Japan can achieve a 90% clean electricity share by 2035. This would also result in a 6% reduction in electricity costs, nearly eliminate dependence on imported LNG and coal, as well as dramatically reduce power se
