This presentation outlines various methods of energy conservation at different levels. It discusses conservation at the household level through efficient appliances and lighting/cooling. At the community level, it recommends utilizing renewable resources like solar and wind energy and timing lighting and elevator use to non-peak hours. Major renewable sources mentioned include solar, wind, hydro, biomass, tidal, and geothermal energy. The concept of energy auditing to identify waste and opportunities for savings is also described. The presentation concludes that education is important to promote conservation awareness and that conservation can improve energy security.

3. INTRODUCTION
r
⚫ Energyconservation refers toefforts
made toreduceenergyconsumption.
Energyconservationcan beachieved
through increased efficient energy
use, in conjunctionwith
decreased energyconsumptionand/o
reduced consumption from
conventional energysources.
⚫ Individualsand organizations that
aredirectconsumersof energychoose
toconserveenergy to reduceenergy
costsand promoteeconomicsecurity.
⚫ Industrial and commercial userscan
increase energy use efficiency to
maximizeprofit.

4. Conservation Of Energy At
Various Levels:-
Energyconservationat household level
Energyconservationatcommunity
level
Energyconservation in industryand
otherplaces
Energyconservation in transportation
sector

5. Energy Conservation At Household
Levels:-
• Energy conservation in major appliances for
domesticuse:-
*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

6. Energy Conservation At
Community Level:-
⚫All unnecessary lights should be turned off especially
when conference roomsetc. are not in use.
⚫Computers, monitors, photocopiersand other
business equipments should be set to their
energy saving mode.
⚫Skylights should be used forwarehouses.
⚫We Should ensure thatoffices having airconditions
have proper windows and all doors are closed when
the airconditioner is in use.

7. Energy Conservation At
Community Level:-
⚫Use Of Renewable
Energy Resources:-
⚫Alternativeresources i.e. renewableenergy sources
should be used in place of nonrenewable energy
sourcese.g. solarenergy, biogas, wind energy etc.
⚫solarenergy forcooking and heating should
promoted.
⚫ Projects involving wind-generated energy for
community and municipal needs should be
demonstrated to thewholecommunity.
⚫Demonstration of biogas programmes is also
required to tell people for theefficient used of it.

8. Major Renewable Energy
Sources:-
⚫Solar Energy
⚫Wind Energy
⚫Hydro Energy
⚫Biomass Energy
⚫Tidal Energy
⚫Geothermal Energy
⚫Bio-fuel

9. Total Renewable Energy Installed Capacity (May 2014)
Renewables : Total installed capacity 31,833.01 MW

10. 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

11. Energy conservation in industry
and other places:-
⚫Auditing
⚫Process modification
⚫Improved measuring
instruments
⚫Energy lossreduction
⚫Light load reduction

12. Energy conservation in
transportation sector:-
⚫Reductionof fuel consumption:-
⚫Carspeed should be maintained as faras possible 50 to 60
km/hr.
⚫Weshould avoid free frequentstarts and stops to reduce
fuel consumption.
⚫We should apply brakes graduallyas faras possible
⚫Fuel economy- maximizing behaviour:-
⚫Moderate driving
⚫ Driving at lowerspeeds
⚫Turning off avehicles engine at stops ratherthan idling &
using cruisecontrol

13. Energy Efficient Devices:-
⚫CFL
⚫Pressurized steam
cooker & Solarcooker
⚫Natural watercooler is a
safe drinking water
devicewhich workson
the principle of “cooling
by evaporation”. No
external sourceof energy
such as electricity or ice
is required.

14. CONCEPT OF ENERGY AUDITING:-
⚫Energy auditing is a systematicapproach to monitor
industrial energy consumption and to find out the
sourcesof energy wastage.
⚫The first and most importantroleof energy auditing is
to identify the areas of energy consumption and to
find theoveruse foraccessing theopportunityof
saving energy.
⚫Analysisof energy use is done for identifying theareas
of energy consumption.

15. Development & Designof Powerplants:-
⚫ Development, design and engineering of
co-generation & captive power plants.
Our engineering consultation services
encompass Design and Engineering of
Co-generation & Captive Power Plants.
Theseservices areexecuted 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 hotgasesand
liquids forgenerationof steam for
process use and power generation.

16. 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
⚫ EnergyWaste- Causes
@Useof lessefficient motors
@Impropersupplyvoltage
@Voltage fluctuations
@Poor power factor
@Lessefficient driven equipment
@Idle running
⚫ By supplying proper voltage
and running the motor on
proper load the efficiency of
the motor can be increased.

17. Total saving in mcl from 95-96 till 2000-2001:-

18. ⚫Maximizereturns from theexisting assets
⚫Reduce losses in transportationand in end use
⚫Initiate action to reduce energy intensity of different
consuming sectors and promoteconservation through
organizational and fiscal measures
⚫Initiate steps to meet the basic energy need of rural and
urban households soas to reduce theexisting inequities.
⚫Maximizesatisfaction of demand forenergy from
indigenous resources
Energy Policy of India – Short term

19. ⚫Progressive steps tosubstitutepetroleum products bycoal,
natural gas and electricity
⚫Action foraccelerated development of all renewable energy
resourcesespecially hydro potential
⚫Promote programmes toachieve self-reliance in energy
sector
⚫Createappropriateorganizational changes in consistent
with theoverall energy strategy
Energy Policy of India –
Medium term

20. ⚫Promotean energy supplysystem, largely based on
renewable sourcesof energy
⚫Promote technologies of production, transportation
and useof energy thatareenvironmentally benign and
costeffective
Energy Policy of India – Long term

21. Advantages:-
⚫Energy conservation can result in increased financial
capital, environmental quality, national
security, personal security, and human comfort.
⚫Energyefficiency saves money.
⚫It is environmental friendly.
⚫It improves indoorairquality
.
⚫Longer life span toappliances.

22. ⚫ Energy is in shortsupply in India, and is expensive, especially for industry.
⚫ Managementof Energy Resources is a important part of power system.So
as tosave natural resources theconservationof energy has todonedoneat
different levels i.e. at social and commercial level.
⚫ With useof moreenergyefficient technologies, many businesses could cut
theirenergyconsumption by up to 20 %
⚫ More renewable resourcescan be used atconsumer level forenergy
conservation.
⚫ It is more important toprovideeducation regarding energyconservation to
thegeneral mass.
⚫ Thus wecan say that Energy Conservationcan improve the possibilityof
Energy fulfillment.
