Abstract:

With the progress of science and technology, the development and use of clean energy resources have become an important way to alleviate the shortage of traditional energy resources and improve the ecological environment. Quantitative assessment of the potential of clean energy resources will help relevant government departments to make scientific decisions on their development and use. Based on model simulation and spatial analysis methods, this study evaluated the potential and value of five major clean energy resources including solar energy, wind energy, hydroelectric potential energy, biomass energy, and geothermal energy in Qinghai Province, and obtained the spatial and temporal distribution pattern and the amount of the main clean energy resources in the province. The results show that: (1) Temporally, the power generation potential of clean energy was increasing year by year from 2000 to 2018. The spatial distribution pattern changed only slightly, and the power generation potential was stable. From a spatial point of view, the clean energy power generation potential in the west of Qinghai Province is relatively high, while that in the east is relatively low; on the prefectural (city) scale, Yushu Prefecture and Haixi Prefecture are in the high value area of clean energy power generation potential, while Xining City is in the low value area; on the scale of ecological function area, the Sanjiangyuan area is in the high value area of clean energy power generation potential, while the Qilian Mountains area is in the low value area. (2) From the perspective of clean energy structure, from 2000 to 2018, Qinghai Province has abundant hydropower resources, with an average power generation potential of 233.841 billion kWh, followed by biomass energy, geothermal energy, solar energy, and wind energy, and the proportion of clean energy in energy consumption is gradually increasing in practical application. (3) The average value of clean energy potential in Qinghai Province from 2000 to 2018 was 188.775 billion yuan. The economic value of clean energy obtained in the future will gradually increase with the development of China’s carbon market and the increase of clean energy development and use intensity. This study provided an important basis for Qinghai Province to understand the current status and future prospect of clean energy resource use in the province, as well as to formulate policies for the development and use of clean energy resources.
