This paper examines energy, drinking water and health nexus in India, and its consequences for the environment and economy. To establish this nexus, K-means cluster analysis and Davies–Bouldin validation index are employed to group 32 Indian states and union territories. The classification was performed based on 16 criteria, and the number of optimal clusters arrived at is 8. The nexus between energy, drinking water and health must be cautiously dealt with to ensure the social and economic growth of the nation. The criterion analysis of the states within these clusters indicates that states and union territories facing energy crises are usually deficient in safe drinking water services; consequently, people of those regions suffer from ill-health, which increases the economic burden on people through the loss of work productivity. With a deficient cash reserve, the communities are incapable of fulfilling the demand for energy and safe drinking water. However, while installing desalination plants to fulfil the need for safe drinking water, their environmental impact must be taken into account, as these systems have high energy consumption and significant environmental impact.

本文考察了印度的能源、饮用水和健康关系，及其对环境和经济的影响。为了建立这种联系，采用 K 均值聚类分析和 Davies-Bouldin 验证指数对 32 个印度州和联邦属地进行分组。分类是基于 16 个标准进行的，得出的最佳集群数为 8 个。必须谨慎处理能源、饮用水和健康之间的关系，以确保国家的社会和经济增长。对这些集群中各州的标准分析表明，面临能源危机的州和联邦领土通常缺乏安全的饮用水服务；因此，这些地区的人们健康不佳，工作生产力下降，从而增加了人们的经济负担。由于现金储备不足，社区无法满足对能源和安全饮用水的需求。然而，在安装海水淡化厂以满足安全饮用水的需求时，必须考虑它们对环境的影响，因为这些系统具有高能耗和显着的环境影响。
