Energy conservation refers to efforts to reduce energy consumption through more efficient use and decreased use of conventional energy sources. This can provide financial, environmental, and security benefits. At the household level, energy conservation includes proper use and maintenance of appliances like refrigerators and washing machines, efficient lighting, and passive solar building design. Responsibility for energy policy in the UK falls mainly to the Department of Energy and Climate Change, along with other departments. Energy conservation is important at various levels including household, community, industry, and transportation.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.
1. Energy Conservation
Dept Of Electrical Engineering 1
1.0 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. Energy conservation can result in increased financial
capital, environmental quality, national security, personal security, and human comfort.
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. In passive solar building
design, windows, walls, and floors are made to collect, store, and distribute solar
energy in the form of heat in the winter and reject solar heat in the summer. This is called
passive solar design or climatic design because, unlike active solar heating systems, it
doesn't involve the use of mechanical and electrical devices. The key to designing a
passive solar building is to best take advantage of the local climate. Elements to be
considered include window placement and glazing type, thermal insulation, thermal mass,
and shading. Passive solar design techniques can be applied most easily to new buildings,
but existing buildings can be adapted or "retrofitted".
Responsibility for energy conservation fall between three Government departments
although is led by the Department for Energy and Climate Change (DECC).
The Department for Communities and Local Government (CLG) is still responsible for
energy standards in buildings, and the Department for Environment, Food and Rural
Affairs (Defra) retains a residual interest in energy insofar as it leads to emissions of CO2,
the main greenhouse gas. The Department for Transport retains many responsibilities for
energy conservation in transport. At an operational level, there are two main non-
departmental governmental bodies ("quangoes") - the Energy Saving Trust, working
mainly in the domestic sector with some interest in transport, and the Carbon Trust,
working with industry and innovative energy technologies. In addition there are many
independent NGOs working in the sector such as the Centre for Sustainable Energy in
Bristol or the National Energy Foundation in Milton Keynes, and directly helping
consumers make informed choices on energy efficiency .

1.1 ENVIRONMENTAL IMPACT ON ENERGY
CONSERVATION:-
Environmental technology (envirotech), green technology (Genentech) or clean
technology (cleantech) is the application of one or more of environmental, green
chemistry, environmental monitoring and electronic devices to monitor, model and
conserve the natural environment and resources, and to curb the negative impacts of
human involvement. The term is also used to describe sustainable energy generation
technologies such as photovoltaics, wind turbines, bioreactors, etc. Sustainable
development is the core of environmental technologies. The term environmental
technologies is also used to describe a class of electronic devices that can promote
sustainable management of resources. Of the 52 percent of the country’s population that
lives in rural areas, 22 percent reside in or near forests. A majority of these people rely on
forest resources for their livelihood, making sustainable land and forest management a
critically important challenge for the Philippines. This section presents the major trends
in land and forest resources management in the country over the past five to ten years.
While there has been some increase in forest cover owing to reforestation efforts and
natural regeneration, per capita forest cover in the Philippines is still the lowest in Asia.
Moreover, the remaining primary or intact forests remain under threat.

2.0 CONSERVATION OF ENERGY AT VARIOUS LEVELS:-
(A)Energy conservation at household level
(B)Energy conservation at community level
(C)Energy conservation in industry and other places
(D)Energy conservation in transportation sector
2.1 ENERGY CONSERVATION AT HOUSEHOLD LEVEL:-
In every country residential demands constitute major part of total energy used.
When comparing an average house to our energy efficient house, it is possible to reduce
annual energy bills up to 40%. We should develop an energy conservation plan for our
house.This is both an environment friendly and economically sound action.The steps in
developing an energy conservation plan for our home are (1) identify the problem areas
where energy is being lost or inefficiently used. (2) to prioritize the problem areas
according to how much energy is being lost or inefficiently used and (3) systematically
correct the prioritized problems according to the limits of our household energy
improvement budget. Apart from lights and fans, several other household appliances have
flooded the market. A cautious operation and use of good quality electrical appliances
(with five star rating) not only enhance their life. but also save energy. Some energy
conservation activities are mentioned below:
2.11 MAJOR APPLIANCES FOR DOMESTIC USE:-
(a) REFRIGERATOR:-
Condenser is found either behind the fridge or underneath the fridge and helps in
maintaining its lower temperature. We can conserve energy while using refrigerator in
the following ways:
It should be maintained at 37ºF- 40ºF and freezer section at 50ºF and should have
automatic moisture control.
We should keep the fridge as full as possible and it should be kept in that position
that its outside surface is not exposed to direct sunlight.
If the door of the fridge is not closed properly it will consume much more energy.
4. Energy Conservation
Dept Of Electrical Engineering 4
Uncovered liquids should not be put in the refrigerators as it will give extra workload
to the compressor.
Before putting food in the refrigerator it should be cooled up to room temperature.
Door of the fridge should not be opened several times.
(b) OVENS/MICROWAVE OVEN:-
To conserve energy while using ovens we should keep in mind the following:
We should use microwaves as they consume 50% less energy than conventional
ovens.
The oven door should not have any cracks or tears in it.
We should use “lids-on” cooking to permit temperature over heating.
Keep reflector pans beneath stove top heating elements bright and clear.
Carefully measure water used for cooking to avoid having to heat needed.
Begin cooking on highest heat until liquid begins to boil. Then lower the settings and
allow food to simmer until fully cooked.
One should cook as much of the meal in the oven at one time as possible.
Rearrange oven shelves before turning your oven on and do not peep in oven. Every
time the oven is opened temperature is lowered by 4° - 5°C.
When preheating an oven for baking, time the preheat period carefully, minutes
should be sufficient.
For large items, stove-top cooking is most efficient, especially with gas.
(c) IRONING:-
Everyday we iron our clothes. It consumes approximately 1000-watt energy,
which is a huge amount. But we can save energy by ironing clothing in bulk and not just
one or two at a time. Ensure that the thermostat on the iron is working and set the right
temperature for the clothing being ironed.
5. Energy Conservation
Dept Of Electrical Engineering 5
(d) COOKING:-
Major part of energy is consumed during cooking. It can be saved during cooking by
using all these measures. Use a cooking pan that is slightly bigger than your cooker plate,
coil or burner. Keep saucepan lids on. Turn down the heat once food starts boiling.
(e) WASHING MACHINES:-
Washing machines consume 20% of the electricity. Energy can be conserved during the
use of washing machine in the following ways:
We should try to use cold water while washing and rinsing as almost 90% of the
energy consumed by washing machine is used to heat the water.
Follow detergent instructions carefully. Adding too much detergent for effective
washing action may require more energy.
Wash only full loads of clothing but do not overload machine.
Soak or prewash the clothes for effective cleaning as well as to reduce energy
consumption.
2.12 LIGHTING:-
Increasing energy demand the world over and the ever-increasing prices of energy
have provided a justifiable reason for improving energy efficiencies of all energy
intensive technologies. Some methods of saving energy during lighting are as follows:
Light should be turned off when not in use.
Maximum sunlight should be used during the day. Bulbs and tubelights should not be
used during day.
Use task lighting whenever possible instead of brightly lighting an entire area or room.
Use compact fluorescent lamps (CFL) in place of incandescent bulbs. A 23-watt
compact fluorescent bulb can replace a 90 or 100 watt.
Use dim light in galleries, lobbies; balconies etc.
Do not keep computer, TV, tape recorder, music system in stand by mode. You can
save 70-kilowatt hour per year.
Geysers consume the maximum amount of electricity. Thermostat can be set to a
lower temperature 45 degreeC to 50 degeeC.
6. Energy Conservation
Dept Of Electrical Engineering 6
Lamps should be put in those corners of the rooms where they can reflect many light
surfaces instead of one.
Use dimmable bulbs wherever possible.
2.13 COOLING:-
A huge amount of energy is wasted in cooling. Following cooling measures can be taken
to conserve energy:
We should open windows at night, to bring cool air inside.
Windows should be closed during daytime.
West facing windows should be shaded. A whole house fan can be used to draw cool
night air into the house.
An evaporative cooler should be installed.
Use room air conditioning only where needed and install energy efficient models.
Cooling in air conditioned houses should be maintained at 25°F.
Regular cleaning of filter in air conditioning systems and cleaning of condenser
conserve energy.
2.2 ENERGY CONSERVATION AT COMMUNITY LEVEL:-
Energy conservation is a very sensitive issue throughout the world. In a society where
money and especially saving of financially advantageous options are available to us, we
should follow the following measures to reduce energy consumption.
All unnecessary lights should be turned off especially when conference rooms etc. are
not in use.
Energy uses should be minimized during peak demand hours.
Set computers, monitors, photocopiers and other business equipments to their energy
saving mode. Turn them off during long idle hours such as lunch breaks.
Skylights should be used for warehouses.
Ensure that offices having air conditions have proper windows and all doors are
closed when the air conditioner is in use.
7. Energy Conservation
Dept Of Electrical Engineering 7
2.21 USE OF RENEWABLE ENERGY RESOURCES:-
Alternative resources i.e. renewable energy sources should be used in place of
non-renewable energy sources e.g. solar energy, biogas, wind energy etc. Energy audits
of homes, buildings, hotels and factories should be done at regular interval.
Demonstration of projects involving the introduction of appropriate, renewable solar
technologies at the community level like solar pumps for water purification and irrigation
of lawns, play grounds, gardens, community centres, as well as 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.
Collaborative community/ academic research and development in order to produce
lowcost, sustainable energy options should be given priority. Environment friendly public
transport system should be promoted to reduce the use of individual motorized transport.
For a single purpose minimum number of vehicles should be used. It will be also helpful
in reducing CO2 emission.

2.22 ENERGY CONSERVATION AT COMMUNITY LEVEL
FOR HOUSING COMPLEXES:-
We require energy for all kinds of work. Cooking, lighting, cooling, transportation etc.
But often the amount of energy which we use is comparatively much less than the
amount of energy which is wasted. As the energy sources are fast depleting, it is
necessary for us to save energy. At the community level following measures can be used:
Installation of photoelectric controls or timers should be used to make sure that
outdoor lighting is sufficient during the day. Open area or yard area lightings should
be switched off after sunrise and again switched on only after sun sets. Tube lights in
common area and staircase landings should be reduced and twin tube light should be
replaced by one tube light. Number of electrical lighting points could be reduced to
one point per room. All additional fittings may be removed permanently or switched
off.
Water pumps should be switched off during non-peak utility hours.
Elevators/lifts should be used for going up beyond three floors and for coming down
the usage of lifts may be reduced. Whenever two elevators/lifts are provided in a
building only single should be operated during “non-peak” hours. Do not allow
children to play with elevators.
Environmentally sustainable transport will promote more mileage less pollution by
GHC gases.
Conservation and sustainable use of water bodies, including watersheds, rivers
barriers and coastal zones will be helpful in the energy conservation at community
level.
Training programme about energy efficient repairs should be organized to conserve
energy at community level. Advocacy to remove subsidies to inefficient and polluting
sources of energy should become essential. Locally manufactured, improved cook
stoves should be introduced to reduce charcoal/fuel consumption.
11. Energy Conservation
Dept Of Electrical Engineering 11
2.3 ENERGY CONSERVATION IN INDUSTRY AND OTHER
PLACES:-
Energy conservation is the practice of decreasing the quantity of energy used. It
may be achieved through efficient energy use, in which case energy use is decreased
while achieving a similar outcome, or by reduced consumption of energy services. At
different places such as factories, business centres, transportation sector and construction
activities, it can be saved in the following ways:
AT FACTORIES AND BUSINESS CENTRES INCLUDING SHOPS:
(a) Auditing:-
Regular monitoring and audit of energy consumption results in energy conservation.
(b) Process modification:-
Process modification means replacement of old and more energy consuming processes by
the new energy efficient processes. Old factories should now employ process
modification.
(c) Improved measuring instruments:-
We can use new technologies and energy efficient instruments and processes to conserve
energy.
(d) Energy loss reduction:-
A lot of energy is wasted everyday. We can reduce energy loss by using following
measures, for example: thermal insulation of fuel tanks can be done, Ceramic fiber
sealing of furnaces, electrical tracing of liquid fuel lines instead of conventional steam
heating.
(e) Light load reduction:-
A significant amount of energy can be saved by reducing light load. Bulbs have been
replaced by tube lights. Nowadays CFLs have proved very helpful in reducing energy
needs for lighting purposes.
12. Energy Conservation
Dept Of Electrical Engineering 12
2.4 ENERGY CONSERVATION IN TRANSPORTATION
SECTOR:-
Transportation includes all vehicles used for personal or freight transportation.
Energy used in this sector, approximately 65% is consumed by gasoline powered vehicles,
primarily personally owned. Diesel powered transport (trains, merchant ship, heavy
trucks etc.) consume about 20% and air traffic consumes most of the remaining15%.
Energy can be conserved in transportation by the following ways:
(a) REDUCTION OF FUEL CONSUMPTION:-
Fuel consumption can be reduced in the following ways:
Use public transportation as much as possible instead of using own vehicles.
Car speed should be maintained as far as possible 50 to 60 km/hr.
Do not use choke unless necessary, when choke is used, put it off as soon as engine is
warmed up, if there is a starting trouble, press clutch to start the engine.).
Avoid free frequent starts and stops to reduce fuel consumption. Release clutch pedal
gradually and simultaneously press accelerator to racing and or jerking.
Never race engine when declutched. Declutch fully when changing gears on clutch
pedal because this increases clutch wear and fuel consumption.
Do not run on hand brake and preferably install a warming light device. Apply brakes
gradually as far as possible. Anticipate need for braking. Switch to lower gears on
gradients (up/down) at the right time. All these will be helpful in reducing fuel
consumption
If possible it is always better to live near workplace.
(b) FUEL ECONOMY- MAXIMIZING BEHAVIOUR:-
Fuel economy maximizing behaviour describes techniques that drivers can use to
optimize their automobile fuel economy. The energy in fuel consumed in driving is lost
in many ways including engine inefficiency, aerodynamic drag, rolling friction and
kinetic energy lost due to braking. They include following measures-
Moderate driving
Driving at lower speeds
13. Energy Conservation
Dept Of Electrical Engineering 13
Using cruise control (speed control or auto cruise controls speed and maintains steady
speed by the driver).
Turning off a vehicles engine at stops rather than idling;
A vehicles gas mileage decreases rapidly at highway speeds, normally above 55 miles
per hour (though the exact number varies by vehicle).
3.0 ENERGY EFFICIENT DEVICES:-
Day by day we see that the demand of energy is increasing all over the world and as
the demand is increasing energy prices are also increasing. Therefore, it is very necessary
to develop energy efficient devices to save energy.
Compact Fluorescent Lamps (CFL) replaced incandescent bulbs.
Fig-2 :- CFL Bulbs
14. Energy Conservation
Dept Of Electrical Engineering 14
Open utensils cooking have been replaced with pressurized steam cooking and of
course solar cooking.
Fig-3 :- Solar Cooker.
Many energy efficient devices can be manufactured and many technologies can be
used for energy conservation. In many industries older and inefficient equipment has
been replaced by new and efficient ones.
Other energy efficient devices which can be used for energy conservation are
diamond hot plate, PRP bullock cart, tubelight with electronic ballast device which
helps in reducing energy consumption by limiting amount of electric current in an
electric circuit.
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

4.0 CONCEPT OF ENERGY AUDITING:-
Energy auditing is a systematic approach to monitor industrial energy consumption
and to find out the sources of energy wastage. It consists of activities that seek to identify
conservation opportunities before conducting or developing any energy saving program.
These audit programs are helpful in understanding and analyzing the energy utilization of
any organization. The audit programmes help to identify and reduce energy wastage.
(a) The role of an energy audit:-
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. In
this way, money can be saved for example during the audit of a factory; the employees of
the factory can be trained for the use of energy saving equipment. Also they would be
made aware of the need for energy conservation. So there is an attitudinal change for
reducing energy use and energy wastage.
It is amply clear that energy auditing plays an important role in energy conservation.
(b)Analysis of energy use:-
Analysis of energy use is done for identifying the areas of energy consumption. This
analysis can be used in the review of management structures and procedures for
controlling energy use. Sub meters can be installed in different plant locations to pinpoint
the actual energy consumption per area. This data could be helpful in allocating energy
use. With the help of this plant manager can list all the equipment used and the
corresponding operating hours. This information can play an important part in creating
spreadsheet information and the charts resulted by can prove useful for analysis.

7.0 CONCLUSION:-
Energy is in short supply in India, and is expensive, especially for industry
Energy-guzzling production procedures further push up costs
With use of more energy efficient technologies, many businesses could cut their
energy consumption by up to 20 %
Adoption of energy efficient technology is picking up the pace, particularly in the
energy intensive industry of India
Energy Conservation Building Code (ECBC) is essential to ensure building energy
efficiency
The term is also used to describe sustainable energy generation technologies such
as photovoltaics, wind turbines, bioreactors, etc. Sustainable development is the core
of environmental technologies. The term environmental technologies is also used to
describe a class of electronic devices that can promote sustainable management of
resources
Thus we can say that Energy Conservation can improve the possibility of Energy
fulfillment.
