Advances in information technology facilitate the construction of data centers (DCs), bringing huge social and economic benefits. However, the rapid development of DCs poses a heavy burden on the environment. To promote economic growth while mitigating environmental impacts, this paper proposes a sustainable development pattern that incorporates DCs and pasture-based photovoltaic (PPV) power stations in cities with rich solar energy but fragile ecological environments. An integrated method framework is applied to show the feasibility and potential of the DC-PPV model. A power generation model based on the DC electricity demand and local climate is established to calculate the installation capacity and pasture area of PPV stations, and a cost-benefit analysis is conducted to find the feasible conditions of the DC-PPV model from financial, technical and environmental perspectives. Then, the environmental potential of the DC-PPV is reflected by the GHG emission reduction from three paths, and the socioeconomic contribution is assessed using input-output (IO) analysis. The results show that the model can facilitate the local economy and effectively reduce carbon emissions. Under the planning DC scale in the study area, the model reduces GHG emissions by more than 3 million tons per year. Moreover, it converts more than 1140 hectares of Gobi land to grassland, which increases the carbon stock by 150,262 tCO2e and saves 39 million yuan of desert management.

生态脆弱地区数据中心与草场农业光伏系统相结合的可持续发展模式

信息技术的进步促进了数据中心(DC)的建设,带来了巨大的社会和经济效益。然而,DC的快速发展给环境带来了沉重的负担。为了在减轻环境影响的同时促进经济增长,本文提出了一种可持续发展模式,该模式在太阳能丰富但生态环境脆弱的城市中采用 DCs 和牧场光伏 (PPV) 电站。应用集成方法框架来展示 DC-PPV 模型的可行性和潜力。建立基于直流电力需求和当地气候的发电模型,计算PPV电站的装机容量和牧场面积,并进行成本效益分析,从财务、技术和环境的观点。然后,DC-PPV的环境潜力通过三个路径的温室气体减排来反映,并通过投入产出(IO)分析评估社会经济贡献。结果表明,该模型可以促进当地经济发展,有效减少碳排放。在研究区规划DC规模下,该模型每年减少温室气体排放量超过300万吨。此外,它将 1140 多公顷的戈壁土地转化为草地,增加了 150,262 吨二氧化碳 结果表明,该模型可以促进当地经济发展,有效减少碳排放。在研究区规划DC规模下,该模型每年减少温室气体排放量超过300万吨。此外,它将 1140 多公顷的戈壁土地转化为草地,增加了 150,262 吨二氧化碳 结果表明,该模型可以促进当地经济发展,有效减少碳排放。在研究区规划DC规模下,该模型每年减少温室气体排放量超过300万吨。此外,它将 1140 多公顷的戈壁土地转化为草地,增加了 150,262 吨二氧化碳2e,节约沙漠治理费用3900万元。
