Damage of Mega Solar Power Plants Due to Heavy Rain - Global warming and sustainable green energy -

Abstract

The decarbonizing is one of the hottest topics in the world. Although the thermal power generation was still high rate in Japan, the renewable energy gradually increased. In particular, the solar power generation, which is a typical renewable energy, is increasing in Japan. Mega solar power plants increased after the 2011 Tohoku earthquake. The heavy rainfall disasters are getting larger and more powerful year after year due to the global warming, some of mega solar power plants were damaged. Typical damages of mega solar power plants were shown in this presentation, and the failure mechanism of mega solar plants was investigated through the experimental studies. Finally, geotechnical slope stability approaches were proposed for the mega solar power plant construction.
