What is meant by Energy conservation ?
.
Reduction in the amount of energy consumed in a process or system through economy. (  This include both initial cost & running cost )

Elimination of  waste.

And rational use.

What Is Energy Audit?

To systematically identify  opportunities for saving energy in the system / plant / process. ( Use of innovative ideas )

To look for the  wastages in a process or equipments.

To study energy consumption pattern in order to assess the productive usage of energy.


The final recommendations for implementation should be economically feasible without much complexities and must give a short payback period.

Similar to financial audit, Reporting is the main objective of energy auditing, and other objective is detection & prevention of errors.

Results of Energy audit must show in savings in one way or other

  1. Initial cost by proper selection of equipment  with latest, suitable to our requirement ( Equipment should not be generalized for use but there must be variants to suite actual site requirement ) with facility to expand in the course of time with minimum changes.

  1. Running cost i.e. electricity & fuel charges and maintenance charges.


  1. Proper selection of equipment and environment result increase in life.
  2. Step I : Preliminary Walkthrough
  3. In this stage, site survey is carried out collecting preliminary data and identifies the potential areas for energy conservation Based on this detailed energy audit is done.
