As a clean and renewable energy, the utilization of geothermal resources has practical significance for adjustment of national energy structure, energy conservation, emission reduction, and the realization of the "dual carbon goals". The Yangtze River Delta is a favorable area for the development and utilization of geothermal resources due to its developed economy, large population density and large reserves of geothermal resources. Based on extensive research and data collection, this paper predicts the demand for building applications of geothermal resources in the Yangtze River Delta, and evaluates and analyzes the potential environmental benefits of geothermal resources development and utilization based on the demand. The results show that the building energy of geothermal resources is abundant, and the environmental benefits are significant in the Yangtze River Delta. It is believed that the comprehensive development and utilization of geothermal resources in the Yangtze River Delta region is very beneficial to promote the "integration" and "high-quality" development of the Yangtze River Delta region.
