The provision of low carbon energy to our society is a key issue at the heart of sustainable development of global energy supply. The Global Energy Interconnection (GEI) Journal publishes original research on theories and developments as well practical applications on principles of large scale low carbon energy generation, transmission, distribution & storage technologies, global energy interconnection & system developments, global energy policy and energy market operations, global climate changes & environmental impacts, global energy transition strategies and global energy governance. GEI journal has been indexed in multiple databases such as EI Compendex, Scopus, Inspec, DOAJ, Elsevier ScienceDirect, etc.The potential for renewable energy to make contributions to mitigating the impact of climate change is expected to increase significantly in the longer term. Renewable energy generation technologies including onshore wind, offshore wind, wave, tidal, marine current, and ocean thermal energy generation as well as PV power generation, which are considered essential to meet long term aim of reducing CO2 emissions, have experienced rapid development and significant progresses during the past 10 years.Decarbonizing the power & energy sector by ramping up the adoption of renewable energy is essential to meet the goals of the Paris Agreement where the required acceleration of the global shift to low carbon can only be achieved through a combination of clean energy generation, modern transmission technologies, power grid interconnectivity, energy storage as well energy policy, which all play important roles in the transition.The scope of Global Energy Interconnection includes the following but not necessarily restricted to:I.Operation and Planning of Global Energy InterconnectionTheoretical analysis and economic incentives to facilitate the implementation of Global Energy InterconnectionConceptual and system development strategies, realization paths and comprehensive values of Global Energy InterconnectionSystem planning, design techniques and tools and economic analysis of Global Energy InterconnectionII.
