16.1 What Is Energy?
Energy is the ability to do work and work is the transfer of energy from one form to another. In practical terms, energy is what we use to manipulate the world around us, whether by exciting our muscles, by using electricity, or by using mechanical devices such as automobiles. Energy comes in different forms - heat (thermal), light (radiant), mechanical, electrical, chemical, and nuclear energy.
16.2 Definition & Objectives of Energy Management:
The fundamental goal of energy management is to produce goods and provide services with the least cost and least environmental effect. The term energy management means many things to many people. One definition of energy management is:
"The judicious and effective use of energy to maximize profits (minimize costs) and enhance competitive positions"
(Cape Hart, Turner and Kennedy, Guide to Energy Management Fairmont press inc. 1997)
Another comprehensive definition is
"The strategy of adjusting and optimizing energy, using systems and procedures so as to reduce energy requirements per unit of output while holding constant or reducing total costs of producing the output from these systems"
The objective of Energy Management is to achieve and maintain optimum energy procurement and utilization, throughout the organization and:
• To minimize energy costs / waste without affecting production & quality
• To minimize environmental effects
16.3 Energy Audit:
Energy Audit is the key to a systematic approach for decision-making in the area of energy management. It attempts to balance the total energy inputs with its use, and serves to identify all the energy streams in a facility. It quantifies energy usage according to its discrete functions.
Industrial energy audit is an effective tool in defining and pursuing comprehensive energy management program. As per the Energy Conservation Act, 2001, Energy Audit is defined
