Abstract: Blockchain technology and renewable energy links can realize the integration of energy flow and information flow. The proposed carbon peak and carbon neutral targets have provided new opportunities and directions for the integration of“renewable energy ＆ blockchain”. Targeting the problems of unclear relationship and unclear development path of the existing research on the integration of“renewable energy ＆ blockchain”,VOSviewer and Scimago Graphica softwares are used to comprehensively analyze the combination of the blockchain and renewable energy management,renewable energy Internet and green power,predicting the future development direction in the field of the renewable energy. The research results can provide a theoretical reference for the current research work and future research direction in the field of“renewable energy ＆ blockchain”and provide strong support for China to achieve the goal of the carbon peak and carbon neutral.
