On 11 March 2011, three reactors of Fukushima nuclear power plant melted down because of the Great East Japan Earthquake. Up until this day, the disaster causes the plant to remain a giant mess. Many residents were forced to leave and still cannot return to their homes. From a long-term perspective, authorities face many challenges including reducing the health risk in Fukushima, disposing of radioactive water properly, safely removing spent fuel rods, and many other social and environmental issues. Thus, the authorities aim to boost alternative renewable power sources such as wind power.
