|Abstract: || 日本於2011年3月發生東日本大地震，伴隨而來的海嘯引發了福島第一核能發電廠的核災事故，使得日本陷入了電力供給不足的危機。|
The occurrence of the Tohoku Earthquake in Japan in March, 2011, accompanied by the tsunami it caused, had resulted in the disaster of Fukushima Daiichi nuclear plant, which made Japan suffer from short supply of power.
Before the Earthquake, nuclear power took 23% of electricity generated nationwide and was considered highly-efficient and safe. However, the aftermath of the Earthquake had caused great anxiety of Fukushima Daiichi nuclear plant’s radiation leak. In response to such panic, Japanese authority ordered all nuclear reactors to be closed, and used fossil-fuel plant to make up the electricity in short.
As waves of public opinion arise among Japanese society, demanding to put nuclear power to an end, the government proposed 3 plans for people to choose from, to end nuclear power completely, to lower the proportion of it to 15%, to 20%~25%, respectively. Meanwhile, people and corporations had once again put their attention to renewable resources, which are cleaner and more sustainable. On the other hand, the tasks of developing renewable resources had become more important than ever, including the higher cost, the environmental limitation, and applicability of such new technology under current policy.
To conclude all above, the author will begin with the research of power supply’s condition in Japan within 2 years of the catastrophe with an aim to explore the applicability of renewable resources and other related study in Japan, and to offer a view of the importance of stable supply of energy when discussing about issues of electricity supply in the country henceforth.
