4. WHAT IS ENERGY?
Energy is the capacity of a physical system to
perform work.
Energy exists in several forms such as heat,
kinetic or mechanical energy, light, potential
energy, electrical or other forms.
According to the law of conservation of
energy, the total energy of a system remains
constant, though energy may transform into
another form.

5. TYPES OF ENERGY
• Mechanical energy
Mechanical energy is energy that results from movement or the location of an
object. Mechanical energy is the sum of Kinetic and Potential Energy.
• Thermal energy
Thermal energy or heat energy reflects the temperature difference between
two systems.
• Nuclear energy
Nuclear energy is energy resulting from changes in the atomic nuclei or from
nuclear
• Chemical energy
Chemical energy results from chemical reactions between atoms or molecules.
There are different types of chemical energy, such as electrochemical energy
etc.
• Electromagnetic energy
Electromagnetic energy is energy from light or electromagnetic waves.

6. Definition of Energy
Management
Energy Management is defined as “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”

7. The Energy Management System

8. The Objectives of Energy Management
1. To achieve and maintain optimum energy
procurement and utilisation, throughout the
organization.
2. To minimise energy costs / waste without affecting
production & quality.
3. To minimise environmental effects.

9. Definition of Energy Audit
• As per Indian Energy Conservation Act 2001,
Energy Audit is defined as:
“The verification, monitoring and analysis of use of energy
including submission of technical report containing
recommendations for improving energy efficiency with
cost benefit analysis and an action plan to reduce energy
consumption “

10. Why the Need for Energy Audit
• The three top operating expenses are energy (both
electrical and thermal), labour and materials.
• Primary objective of Energy Audit is to determine ways
to reduce energy consumption per unit of product
output or to lower operating costs.
• Energy Audit provides a “ bench-mark” (Reference
point) for managing energy in the organization.

11. Types of Energy Audits
1. Preliminary Energy Audit
2. Targeted Energy Audit
3. Detailed Energy Audit

12. Energy Audit Instruments
1. Electrical System Parameters

13. 2. Combustion Analyzer
This instrument has in-built chemical cells which
measure various gases such as O2, CO, NOxand SOx.

14. 3.Temperature measurements
(a) Contact thermo meter
These are thermocouples which measures for example flue gas, hot air,
hot water temperatures by insertion of probe into the stream

15. (b) Infrared thermometer
This is a non-contact type measurement which when directed
at a heat source directly gives the temperature read out.
This instrument is useful for measuring hot spots in furnaces,
surface temperatures etc.

16. 5. Leak detectors
Ultrasonic instruments are available which can be used
to detect leaks of compressed air.
Other gases which are normally not possible to detect
with human abilities.
Compressed Air Leaks.
Steam Leak.

17. 6. Measurement of light
Lux meters Illumination levels are measured with a lux
meter.
It consists of a photo cell which senses the light output,
converts to electrical impulses which are calibrated as lux.

18. Technical and Economic feasibility-
Factors
Sample Worksheet for Economic Feasibility
Name of Energy Efficiency Measure
i. Investment
a. Equipments
b. Civil works
c. Instrumentati
on
d. Auxiliaries
2. Annual operating costs
• Cost of capital
• Maintenance
• Manpower
• Energy
• Depreciation
3. Annual savings
• Thermal Energy
• Electrical Energy
• Raw material
• Waste disposal
Net Savings /Year (Rs./year)
= (Annual savings-annual operating costs)
Payback period in months
= (Investment/net savings/year) x 12
Technology availability, space, skilled man power, reliability,
service, Impact of measure on safety, quality, production or
process. Maintenance requirements and spares availability
