After a scrutinizing peer review process, 20 articles were accepted and published. These articles fall into four main areas: renewable energy cutting edge technologies, energy storage, energy modelling techniques and, climate and energy policy and impacts. Cross-areas articles belong to this Special Issue covering almost all the Sustainable Development Goals (SDGs)
