待能源管理项目准备好、能源组织建立以后，下一个阶段是分析和计划工作，在第二节中我们已经解释了，计划工作是在考虑过去、现在和将来的基础上制定的，在分析和计划阶段必须牢记这部分内容，分析企业能源用于何处？是怎么用的？能源数据的分析应包括以下几个阶段：（1）回顾过去能源利用的情况；（2）能量审计；（3）工程分析；（4）经济分析。
After the energy management project is ready and the energy organization is established, the next stage is analysis and planning work. As we have explained in the second section, planning work is formulated based on considering the past, present, and future. In the analysis and planning stage, it is necessary to keep this part in mind and analyze where the enterprise's energy is used? How is it used? The analysis of energy data should include the following stages: (1) reviewing the past energy utilization situation; (2) Energy audit; (3) Engineering analysis; (4) Economic analysis.
能源调查
Energy survey
历史情况的调查可以根据公共电力公司的电费帐单、工厂的记录、生产统计或其他可能得到的资料来完成。调查的任务是了解能源利用的长期和短期的趋向，诸如能源管理项目试图要改进能源利用，是以什么为参基准。另外要考虑的是，过去的用能结构及其在能源管理项目中的重要性。
The investigation of historical situations can be completed based on the electricity bills of public power companies, factory records, production statistics, or other possible information. The task of the investigation is to understand the long-term and short-term trends in energy utilization, such as the benchmark against which energy management projects attempt to improve energy utilization. Another consideration is the past energy consumption structure and its importance in energy management projects.
