Owing to old and obsolete industrial technologies and machinery the extent of energy wastage is very high. Energy Conservation potential in the industrial sector of our nation has been projected between 30 to 40 %. Good energy management begins with an energy audit. Effective management of energy-consuming systems can lead to significant cost and energy savings as well as increased comfort, lower maintenance costs, and extended equipment life. A successful energy management program begins with a thorough energy audit. The energy audit evaluates the efficiency of all building and process systems that use energy. Energy audits don't save money and energy for companies unless the recommendations are implemented. Audit reports should be designed to encourage implementation, but often they impede it instead. In this paper, the discussion on the scope and objectives of energy audit, types of energy audit, contents of an energy audit, audit methodology and targets and benefits of the energy audit are presented. Finally a typical case study of chemical industry for energy audit is discussed with a clear and consistent path toward introducing energy management and auditing. The methodology, tools used, results and difficulties encountered during the study are also discussed.  Key words: energy demand, energy conservation, energy audits, audit report, energy cost, case study, chemical industry [1] Introduction The energy crisis all over the world in the seventies warned the mankind and forced to think about the appropriate utilization of the energy resources on the earth for the sustainable development. In history, the energy crisis had led to many innovations as well as research and development programs in all sectors related to the energy. It is well known that energy sector has its own impact on the progress and development of any nation. The availability of various energy resources and in house capability to use it in the appropriate manner for productive development of a nation is the key factor in the economic growth of the country. [2] Energy Audit What is an Energy Audit? This is a diagnostic study to scan entire energy scenario of a facility and work out  Energy Conservation  Opportunities. The study includes historical data analysis, of existing energy monitoring and operational practices, process evaluation, and cost benefit analysis of the  Energy Conservation.  It focuses on specific areas of the site’s energy system, such as natural gas boilers, steam distribution, motor systems, refrigeration, and compressed air, venting systems and related water and wastewater discharge issues. 2.1 Role of Energy Audit To institute the correct energy efficiency programs, we have to know first which areas in our establishment unnecessarily consume too much energy. An energy audit identifies where energy is being consumed and assesses energy saving opportunities. In the factory, doing an energy audit increases awareness of energy issues among plant personnel, making them more knowledgeable about proper practices that will make them more productive. An energy audit in effect gauges the energy efficiency of plant against “best practices”. When used as a “baseline” for tracking yearly progress against targets, an energy audit becomes the best first step towards saving money in the production plant.
