加利福尼亚州最近的能源危机要求研究一系列潜在的节能措施。虽然之前通过节约热水的狭隘视角认识到了这一点，但通过节约水资源来节约潜在能源的观点扩大了，在适用的情况下，将供水泵送、处理和分配给客户以及废水处理过程的能耗方面纳入了考虑范围。本文介绍了通过节水措施（包括住宅洗衣机、商用洗衣机和商用洗碗机）的潜在收益量化节能的基本考虑因素。 从更一般的意义上讨论了根据其他节水措施（如减少室外用水）进行的节能概述。考虑到公用事业运营和维护成本的降低，这些信息对公用事业的技术专业人员在评估节水项目更广泛的成本效益分析范围时非常有用。评估节约用水带来的能源效益也有效地结合了向零售和批发供水机构以及电力公司提供的整体资源供应角度。在更大的背景下，能源和水资源节约组合的量化可以提高各自需求预测的准确性，从而在为美国各地的各个社区执行时加强综合资源规划。 包括15个参考文献、表格和图表。

The recent energy crisis in California required looking into a broad range of potential energy savings. Although recognized previously through the narrow perspective of hot water savings, the view on potential energy savings through water conservation widened to incorporate as applicable the energy consuming aspects of water supply pumping, treatment and distribution to customers along with wastewater treatment processes. This paper presents the basic considerations in quantification of energy savings through the potential gains of water conservation measures, including residential clothes washers, commercial clothes washers and commercial dishwashers. An overview of energy savings in light of other water conservation measures such as reductions in outdoor water use is discussed in a more general sense. This information is useful to technical professionals at utilities in assessing the broader scope of cost-benefit analyses of water conservation programs given the reductions in operations & maintenance costs to utilities. Assessing energy benefits from water conservation also effectively incorporates the overall resource supply perspective provided to not only retail and wholesale water agencies but also electric utilities. In a larger context, the quantification of combined energy and water savings enables more accuracy in respective demand forecasts and thus enhances integrated resource planning when performed for individual communities throughout the United States.
