“开源节流”听半导体工学博士德山巍的讲演,得知目前日本每年使用的能源有百分之九十是靠从国外输入石油、煤炭等。日本人口众多、经济发达,但国土狭窄、资源缺乏,因此能源成为一大问题。中国有句成语,叫做“开源节流”。现在,日本采取种种办法来节省能源,诸如对冬天取暖的温度、高速公路的车速加以适当的限制等等,这些都是属于“节流”的一面。但是,更重要的一面是“开源”。这里说的当然不是奢望从日本土地上开发出大量的石油和煤炭来,而是指开发新能源,诸如太阳能、原
According to a lecture by Tokuyama Sun, Ph.D. in semiconductor engineering, the report said that at present, 90% of the energy used in Japan each year depends on importing oil and coal from abroad. Japan has a large population and an economically developed economy. However, with a narrow territory and a lack of resources, energy has become a major problem. There is an idiom in China called “increasing income and cutting expenditure.” Now Japan has taken various measures to save energy, such as the temperature of winter heating and the speed limit of expressways, which are all “throttling” aspects. However, the more important aspect is “open source.” It is certainly not the case here to expect to develop large quantities of oil and coal from Japanese soil but to develop new energy sources such as solar energy,
