INTRODUCTION
 Energy conservation refers to efforts
made to reduce energy consumption.
Energy conservation can be achieved
through increased efficient energy
use, in conjunction with
decreased energy consumption and/or
reduced consumption from
conventional energy sources.
 Individuals and organizations that
are direct consumers of energy choose
to conserve energy to reduce energy
costs and promote economic security.
 Industrial and commercial users can
increase energy use efficiency to
maximize profit.

Conservation Of Energy At
Various Levels:-
Energy conservation at household level
Energy conservation at community
level
Energy conservation in industry and
other places
Energy conservation in transportation
sector
Energy Conservation At Household
Levels:-
• Energy conservation in major appliances for
domestic use:-
*Energy Conservation in Refrigerator
*Energy Conservation in Oven/Microwave Oven
*Energy Conservation in Ironing
*Energy Conservation in Cooking
*Energy Conservation in Washing machine
• Energy Conservation During Lighting
• Energy Conservation During Cooling
Energy Conservation At
Community Level:-
 All unnecessary lights should be turned off especially
when conference rooms etc. are not in use.
 Computers, monitors, photocopiers and other
business equipments should be set to their
energy saving mode.
 Skylights should be used for warehouses.
 We Should ensure that offices having air conditions
have proper windows and all doors are closed when
the air conditioner is in use.
Energy Conservation At
Community Level:-
Use Of Renewable Energy
Resources:-
 Alternative resources i.e. renewable energy sources
should be used in place of nonrenewable energy
sources e.g. solar energy, biogas, wind energy etc.
 solar energy for cooking and heating should
promoted.
 Projects involving wind-generated energy for
community and municipal needs should be
demonstrated to the whole community.
 Demonstration of biogas programmes is also
required to tell people for the efficient used of it.
.
Major Renewable Energy
Sources:-
 Solar Energy
 Wind Energy
 Hydro Energy
 Biomass Energy
 Tidal Energy
 Geothermal Energy
 Bio-fuel
Total Renewable Energy Installed Capacity (May 2014)
Renewables : Total installed capacity 31,833.01 MW
Energy Conservation At
Community Level:-
Energy Conservation At Community
Level For Housing Complexes:-
 Installation of photoelectric controls or timers should
be used
 Water pumps should be switched off during non-peak
utility hours
 Only single Elevator/Lift should be operated during
“non-peak” hours
 Training programme about energy efficient repairs
should be organized
 Locally manufactured, improved cook stoves should be
introduced to reduce charcoal/fuel consumption
Energy conservation in industry
and other places:-
Auditing
Process modification
Improved measuring instruments
Energy loss reduction
Light load reduction
Energy conservation in
transportation sector:-
 Reduction of fuel consumption:-
 Car speed should be maintained as far as possible 50 to 60
km/hr.
 We should avoid free frequent starts and stops to reduce
fuel consumption.
 We should apply brakes gradually as far as possible
 Fuel economy- maximizing behaviour:-
 Moderate driving
 Driving at lower speeds
 Turning off a vehicles engine at stops rather than idling &
using cruise control
Energy Efficient Devices:-
 CFL
 Pressurized steam
cooker & Solar cooker
 Natural water cooler is a
safe drinking water
device which works on
the principle of “cooling
by evaporation”. No
external source of energy
such as electricity or ice
is required.
CONCEPT OF ENERGY AUDITING:-
 Energy auditing is a systematic approach to monitor
industrial energy consumption and to find out the
sources of energy wastage.
 The first and most important role of energy auditing is
to identify the areas of energy consumption and to
find the overuse for accessing the opportunity of
saving energy.
 Analysis of energy use is done for identifying the areas
of energy consumption.
Development & Design of Power plants:-
 Development, design and engineering of
co-generation & captive power plants.
Our engineering consultation services
encompass Design and Engineering of
Co-generation & Captive Power Plants.
These services are executed with in the
shortest frame of time and meet the
consultation requirements for:
 Co-generation power plants for sugar
mills, rice mills, maize processing plants,
industrial sector, etc.
 Waste heat recovery from hot gases and
liquids for generation of steam for
process use and power generation.
Department of Electrical Engg.
ENERGY CONSERVATION IN ELECTRICAL
MOTORS
 Motor Efficiency =O/P Power/Input
PowerX100
Watt Losses-
Stator & rotor losses
Iron Losses
Friction & Windage losses
Stray Load losses
 Energy Waste- Causes
@Use of less efficient motors
@Improper supply voltage
@Voltage fluctuations
@Poor power factor
@Less efficient driven equipment
@Idle running
 By supplying proper voltage
and running the motor on
proper load the efficiency of
the motor can be increased.
Total saving in mcl from 95-96 till 2000-2001:-
 Maximize returns from the existing assets
 Reduce losses in transportation and in end use
 Initiate action to reduce energy intensity of different
consuming sectors and promote conservation through
organizational and fiscal measures
 Initiate steps to meet the basic energy need of rural and
urban households so as to reduce the existing inequities.
 Maximize satisfaction of demand for energy from
indigenous resources
Energy Policy of India – Short term
 Progressive steps to substitute petroleum products by coal,
natural gas and electricity
 Action for accelerated development of all renewable energy
resources especially hydro potential
 Promote programmes to achieve self-reliance in energy
sector
 Create appropriate organizational changes in consistent
with the over all energy strategy
Energy Policy of India –
Medium term
 Promote an energy supply system, largely based on
renewable sources of energy
 Promote technologies of production, transportation
and use of energy that are environmentally benign and
cost effective
Energy Policy of India – Long term
Advantages:-
 Energy conservation can result in increased financial
capital, environmental quality, national
security, personal security, and human comfort.
 Energy efficiency saves money.
 It is environmental friendly.
 It improves indoor air quality.
 Longer life span to appliances.
 Energy is in short supply in India, and is expensive, especially for industry.
 Management of Energy Resources is a important part of power system.So
as to save natural resources the conservation of energy has to done done at
different levels i.e. at social and commercial level.
 With use of more energy efficient technologies, many businesses could cut
their energy consumption by up to 20 %
 More renewable resources can be used at consumer level for energy
conservation.
 It is more important to provide education regarding energy conservation to
the general mass.
 Thus we can say that Energy Conservation can improve the possibility of
Energy fulfillment.
