Post-disaster resilience of a 100% renewable energy system in Japan

摘要: Following the 2011 Fukushima nuclear disaster, Japan is having to re-design its energy policy. With danger of power in an earthquake-prone country exposed, renewable energies are being seen as a potential alternative. An assessment feasibility 100% electricity system by year 2030 was shown be able achieve higher level resilience. The based on simulation hourly future production wind and solar meteorological data, that can cope with estimated demand for 2030. Such would use pump-up storage electric batteries balance daily fluctuations supply demand, though most important challenge providing sufficient meet summer peak. These findings have import implications at policy making level, it shows Japanese generation technically increase share renewables up 100%, guaranteeing stable reliable supply.
