Assessment the effectiveness of energy consumption in the enterprises of the main transport of gas
- Authors:
- T. F. Konoplev
This study proposed a new comprehensive approach to assessing energy efficiency in the enterprises of the main transport of gas, which allows you to explore in detail the consumption of energy resources of each equipment, consumption of resources in technological operations and the creation of favorable conditions, to assess the state of accounting systems and the organization works to improve the efficiency use of energy.
