With the continuous reduction in the availability of fossil energy along with the increasingly severe climate change situation and the increasing accumulation of environmental pollution, higher requirements have been put forward for energy reliability, environmental protection and sustainable development. Clean development is the core of sustainable development, and the key to clean development is clean energy power generation technology. After years of development, clean energy power generation technology has achieved considerable progress. Hydropower generation, wind power generation, and photovoltaic PV power generation technologies are now widely applied, and concentrating solar power CSP generation, geothermal power generation, and ocean power generation also present strong development potential. Such advancements and the reduction in cost of clean energy power generation is the most important driving force for the transition to clean energy and the construction of a Global Energy Interconnection.This report contains 6 chapters in total to cover the 6 main clean energy power generation technologies currently available. Each chapter introduces the basic principles of one technology; summarizes its development status based on the investigation results; analyzes the main difficulties that is faced by each technology in conjunction with the demands for clean energy transition; proposes its development goals and research directions in the future through technical and economic research based on the assessment of technology readiness; analyzes the main technical factors affecting the economic efficiency, and determines the trend of changes in the economic efficiency based on the development goal by applying the analysis method which combines the multiple linear regression method with the deep self- learning neural network.Global Energy Interconnection is an optimum solution with the aim of realizing the optimal allocation of clean energy and alleviating complex issues such as the global energy dilemma and climate environment. Clean energy power generation technology is the foundation forthe development of the Global Energy Interconnection and has broad development space and application prospects. This report, as one of the key technology achievements of the Global Energy Interconnection, is intended to enable readers to know thecurrent statusand key development trends of main clean energy power generation technologies, and provide an important reference for people inside and outside the industry, especially policy makers, to fully understand the clean energy power generation technologies. Additionally, itis of great significance to further consolidate the technical foundation of the Global Energy Interconnection, promote the large-scale development, global deployment and efficient utilization of clean energy, and realize the sustainable development of economies, societies and the environment around the world.
