Renewable energy sources such as solar and wind power are essential to achieving carbon neutrality in the future. Japan's Global Warming Prevention Plan calls for the maximum introduction and use of renewable energy. Against this backdrop, the adoption of renewable energy is accelerating in all sectors, including the government, local governments, businesses, and individuals.

The amount of electricity generated by renewable energy sources such as solar and wind power is affected by weather conditions. The amount of electricity generated by solar power varies depending on weather conditions such as the amount of sunlight and temperature, while the amount of electricity generated by wind power varies depending on weather conditions such as wind direction and speed. Future climate change will change weather conditions, and the amount of electricity generated from renewable energy sources will change accordingly. Previous studies in Japan have projected the impact of climate change on the amount of renewable energy potential.

In addition, climate change is expected to intensify natural disasters. As a result, for example, floods may inundate renewable energy production areas, and concerns about the impact on power generation exist. However, no examples of studies have evaluated the impact of such natural disasters on renewable energy production areas and the impact on power generation in Japan. In this study, we evaluated the impact of natural disasters on the energy potential of solar and wind power, assuming multiple levels of natural disasters, with a focus on flooding and sediment disasters. We will present the results of this study.
