The Japan Experience: The Earthquake that Gave a Jolt to Solar Energy

There was very little good that came out of the 2011 Fukushima disaster in Japan. The disaster did, however, cause Japan to rethink its dependency on nuclear power and caused a significant shift in the energy strategy for the country.ty.jpg

Japan quickly identified renewable energy as the solution to a sustainable and reliable energy supply. Japan has become a major player in the solar industry, according to Bloomberg Business, with plans this year to install up to 12.7 gigawatts of solar power. Japan is an archipelago, which the National Geographic defines as a “group of islands closely scattered in a body of water”, and is occupied by hundreds of millions of people which does not leave an abundance of space to install solar panels. Recently, however, Japanese electronics manufacturer Kyocera has identified more than one method of efficiently utilizing space in and around the country’s land to install as many solar panels as possible in otherwise dead space.

In June 2015, The Huffington Post reported that Kyocera had built two massive solar power stations that were placed on waterproof structures floating on two separate reservoirs in Kato City, Japan. The article described the systems as containing close to 9,000 solar panels and placed on waterproof structures made of polyethylene. The systems are claimed to be weather-proof and earthquake-proof, having withstood controlled hurricane wind tests. Each year the systems will produce an expected 3,300 megawatt hours of solar energy. The systems would not take up scarce land space and would even generate electricity more efficiently according to the Huffington Post due to the “cooling off effect of the water underneath the system.”

Another efficient use of Japanese land to house solar projects came in an unlikely form: golf courses. In July 2015, Quartz reported another Kyocera project in which a 23-megawatt solar plant was built on an abandoned golf course in Kyoto, Japan. It is scheduled to begin energy generation in 2017 and the expected energy production is reported to exceed 26,000 megawatt hours per year. The abandoned golf course, according to Quartz, is one of many in Japan that were built during a rise in the popularity of golf during the 1980’s, which eventually fell in the decades to come. This resulted in the abandonment of golf courses all over Japan which left unused land to go to waste. In both the water reservoir and golf course projects Kyocera is selling the solar energy to local utilities.

 The Japanese government is beginning to develop a recycling program for the future once all of these modules they’ve invested in exceed their lifespan. According to PV-Tech, the expected lifespan for these models is about 25 years. PV-Tech reported that due to the fact that Japan began awarding its feed-in tariff for solar in 2012, which spurred many investments in solar power modules during that period of time, it is predicted by the Japanese Environment Ministry that by 2040, there will be a massive influx of used solar modules in landfill sites all over the country. To prevent this, the Ministry announced that it will “begin to implement measures for ‘removal, transportation and processing of solar power generation equipment’ before the end of this fiscal year, March 2016”, according to PV-Tech.  

Japan, after being devastated by a natural disaster, is strategically planning its recovery to avoid a repeat of the 2011 Fukushima disaster while also investing in renewable energy that will benefit the environment and produce profits in the foreseeable future. These Kyocera projects demonstrate the potential available to maximize the efficiency of solar energy production with just a little creativity and ingenuity.
