日本自1892年第一座水电站建成投入运行起,日本的水力发电已有100多年的历史,迄今,日本已开发了60%的水电资源。随着50年代能源需求的急剧上升,建设大规模的水库型水电站,如佐久间(Sakuma)和黑部川(Kurobe-gawa)4~#工程,作为电源在维持高经济增长中的支柱,起到了重要的作用。然而,随着实惠型水电站的不足以及能源需 Since the first hydropower station was put into operation in 1892 in Japan, hydroelectricity in Japan has a history of more than 100 years. To date, Japan has developed 60% of hydropower resources. With the rapid rise in energy demand in the 1950s, large-scale reservoir hydropower stations such as Sakuma and Kurobe-gawa 4 ~ # were built as the pillars of the power supply in sustaining high economic growth. To the important role. However, with the lack of affordable hydropower stations and energy needs
