How to increase energy efficiency?
Basic methodology of management
To repeat “P-D-C-A” circle is very effective and important.

Three Steps to Promotion of Energy Conservation

	Measures	Description
Step 1	Enhancement of management, Improvement of operation	To enhance energy management based on the current setup, so as to improve operation (at least measuring instruments may be required)
Step 2	Improvement and additional installation of equipment	To improve or retrofit some facilities with only a small investment, so as to achieve higher energy efficiency as well as to recover waste energy
Step 3	Changes in process, Introduction of high-efficiency equipment	This step is intended for improving or updating process and manufacturing equipment It involves technical development and large-scale investment, but on the other hand produces a substantial
