1. Theory innovation
GEI is a globally interconnected strong and smart grid with UHV grid as the backbone, which will serve as a platform for extensive development, deployment and utilization of clean energy globally. In essence, GEI is "Smart Grid + UHV Grid + Clean Energy". Smart grid is the foundation, UHV grid is the key, and clean energy is the priority. The construction of Global Energy Interconnection will facilitate a large-scale development and exploitation as well as a wide-scope coordination and balance of clean energy, promote energy revolution and sustainable development, and thoroughly solve the problems that restrict the development of human society involving energy security, environmental pollution and greenhouse gas emission.
Smart grid is the foundation
Smart grid possesses the features of informatization, automization and interaction, which enable the integration and control of large-scale clean energy generation, and meet the demand for flexible access of distributed power supply and smart equipment.
UHV grid is the key
UHV grid is the backbone grid of Global Energy Interconnection and the carrier of long-distance transmission and optimization allocation of clean energy.
Clean energy is the priority
The wind power in arctic region, solar power generation in equatorial region, centralized and distributed clean energy generation of all continents and countries will be the leading energy in the future.
2．Global energy outlook
Global energy outlook is the fundamental viewpoint and theory concerning sustainable development of global energy. Its core content is investigate and solve energy problems from the global, historical, difference and open viewpoints. Its strategic priority is to expedite the construction of Global Energy Interconnection, make an overall development, allocation and utilization of global energy, ensure the safe, clean, efficient and sustainable supply of global energy, and realize the coordinated development of energy resources, economy, society and environment.
GEI takes electricity as the center point in promoting transition of energy development modes, power balance as the pillar of energy balance, electric power generation as the main solution of primary energy conversion and utilization and grid as the fundamental platform for energy allocation, to expedite the formation of electricity-centered pattern in energy development and utilization, improve electrification level and energy efficiency, and promote sustainable development of energy.
In energy development, "Clean energy Replacement" should be deployed, that is, to replace fossil energy by clean energy, in order to realize strategic transformation of energy structure to be clean energy-dominance. In energy consumption, "Electricity Replacement" should be deployed, that is, to replace coal and oil with clean electricity from afar, so as to increase the proportion of electric energy in end-use energy consumption.
The construction of the Global Energy Interconnection will adopt the mode of prioritizing the easiest and the nearest to gradually achieve the short-term target by 2020, the medium-term target by 2030 and the long-term target by 2050.
The short-term target (2020)
