脱炭素化・カーボンニュートラルへ向けた再生可能エネルギーの積極的な活用が進んでいる。国内外にて、再生可能エネルギーの導入量が飛躍的に増加し、電力システムに対する存在感も大きい。しかし、自然変動性や資源の偏在性により、再生可能エネルギーは安定した主力電源としての運用には課題もある。一方、再生可能エネルギーの資源量・変動要因・予測可能性等を理解した上で、他の電源や蓄エネルギー技術（揚水発電や蓄電池、EV、水素燃料など）と組み合わせることでエネルギーシステムの柔軟性も期待できる。そのためにも、 地球科学分野が持つ多様で膨大な観測データ、モデリング技術、幅広い知見を共有し、それらをエネルギー分野への活用やその有用性を評価することも重要である。
本セッションでは、再生可能エネルギー分野全般（太陽光、風力、地熱・地中熱、海流・潮流、波力、バイオマス発電）・電力需要や電力系統への気象条件の影響などの講演を広く募集し、地球科学情報の活用について分野横断的に議論し、地球科学の役割について広く意見交換を行うことが目的である。

Renewable energy is increasing dramatically in the world. Renewable energy power generations have become a strong presence in grid operations. However, it is a challenge for renewable energy to be stable power sources due in part to natural variability of renewable energy. For effective use of renewable energy, a combinational of various power resources and energy storage technologies (e.g., pumped-storage power generation, storage battery system, electric vehicles) should be desired. Therefore, we need to understand the amount of renewable resources, causes of variation, and the predictability of power output. Then, observation and forecast information from earth science fields should be analyzed and applied to power energy fields to achieve easy use of earth science databases. 
Recently, observation databases from remote sensing technology and/or forecasts from numerical models have become essential for both renewable energy and electric power system. Impacts of both earth science data and optimization are essential to economic evaluation of grid operations. 
This proposed session needs your presentation from the whole of renewable energy fields (wind power, solar power, geothermal power, tidal power, wave power and biomass power generations) and from the studies of impacts of weather conditions on energy demand and power systems. Our goal of this session is to exchange views with various researchers between renewable energy fields and earth science fields (e.g., usage-trends of earth science datasets for renewable energy, earth science datasets availability, integrated studies, energy resources in future, and a request from renewable energy fields to earth science fields).
