Assessment of Shallow Geothermal Development Potential Based on the Entropy Weight TOPSIS Method—A Case Study of Guizhou Province

Shallow geothermal energy is a renewable and clean resource, yet its potential varies significantly across different regions of China. The disparity in resource conditions, technology development, and the level of regional understanding regarding its potential hinder efficient utilization. This study applies the entropy weight method, combined with the TOPSIS model, to assess the shallow geothermal utilization potential across various regions of the country, with a case study in Guizhou Province employed to evaluate the actual development potential. Additionally, SWOT analysis is employed to assess regional development and provide recommendations for the future growth of shallow geothermal energy in Guizhou. The findings indicate a high potential for shallow geothermal energy in East China, with significant resource potential and conceivable economic benefits in Guizhou Province. This research not only evaluates the development potential for shallow geothermal energy in different regions but also proposes strategic recommendations to enhance its effective development and contribute to the high-quality transformation of the energy industry.
