The document discusses global energy interconnection (GEI) and the Global Energy Interconnection Development and Cooperation Organization (GEIDCO). It summarizes GEIDCO's view of GEI as an infrastructure platform to massively develop, transmit, and utilize clean energy worldwide using ultra-high voltage grids and smart grid technology. The document outlines GEIDCO's management structure, membership, and regional offices. It provides examples of cooperation projects between countries to interconnect power grids and develop clean energy. Finally, it presents GEIDCO's proposed roadmap and backbone network for the development of GEI over domestic, intra-continental, and intercontinental phases by 2050.
