Energy today has become a major factor in deciding the product cost at entry level as well as at the higher levels. Energy cost is a significant factor in economic activities as it is with factors of production like capital, land and labour. The requirements of an energy shortage situation calls for energy conservation measure, which essentially mean using less energy for the same level of activities. Energy Audit balances the total energy inputs with its use and the energy that is used in subsequent process. Energy Audit helps in energy cost optimization, pollution control, safety aspects and suggests the methods to improve the operating & maintenance practices of the system. It is instrumental in coping with the situation of variation in energy cost availability, reliability of energy supply, decision on appropriate energy mix, decision on using improved energy conservation equipments. instrumentations and technology

Objectives of Energy Audit

The Energy Audit provides the vital information base for overall energy conservation program covering essentially energy utilization analysis and evaluation of energy conservation measures. It aims at:

Identifying the quality and cost of various energy inputs.
Assessing present trend of energy consumption in different cost centers of operations.
Relating energy inputs and production output.
Identifying potential areas of thermal and electrical energy economy.
Highlighting wastage in major areas.
Fixing of energy saving potential targets for individual cost centers.
Implementation of measures for energy conservation & realization of savings.

Up to the mark energy audits are performed with the help of detailed study of the following which ultimately helps in Energy Conservation and its cost reduction like:

1. Energy mapping.
2. Power Quality Analysis.
3. Peak load management.
4. Energy efficiency.
