Evaluation of renewable energy resources abundance and spatial correlation analysis in Beijing

Beijing is actively exploring the development and utilization potential of local renewable energy resources in order to speed up the adjustment of energy structure, implement clean energy substitution and build a modem green energy system in the capital. In this context, it is urgent to systematically analyze the status and characteristics of renewable energy resources in Beijing. Taking Beijing as the research area, this paper calculates the abundance indexes of solar energy, wind energy and biomass resources respectively, and establishes the renewable energy abundance evaluation model. Based on the spatial distribution characteristics of renewable energy resources in Beijing, the spatial correlation of renewable energy resources was tested. The results show that renewable energy resources in Beijing are generally characterized by "rich in the north and poor in the South" and "rich in the surrounding areas and poor in the center". Among them, solar energy resources are relatively rich, wind energy resources are scarce with random distribution characteristics, and biomass resources are decreasing year by year. The research results can provide important reference for the development and utilization of renewable energy resources in different regions of Beijing.
