Energy Conservation
Energy conservation effort made to reduce the consumption of energy by using less of an energy service.
This can be achieved either by using energy more efficiently or by reducing the amount of service used.
Energy conservation reduces the need for energy Services and can result in increased environmental quality national security, personal financial security and higher savings.
Energy can be conserved by reducing wastage and losses, improving efficiency through technological upgrades and improved operation and maintenance.
On a global level energy use can also be reduced by the stabilization of population growth.
In the case of fossil fuels, the conservation also can include finding new ways to tap into the Earth's supply so that the commonly used oil fields are not drained completely.
It is important today to conserve in every field particular for industry where energy is being used in various forms. This presentation will take you through various utilities where there are chances to conserve energy and save environment.

NATIONAL GREEN CORPS, NATIONAL SERVICE SCHEME, CLIMATE EDUCATION AND ENERGY C...W G Kumar
A training module to introduce College Lecturers and School Teachers to the subject of Climate Education and Live Projects that they can do in their institution and elsewhere
According the Department of Energy’s 2010 Buildings Energy Data Book, the average commercial building in the United States consumes $.70 of electricity per square foot in lighting costs annually. Meanwhile, 13 percent of commercial buildings in the United States are between 25,000 and 50,000 square feet. So by the math, for a typical 35,000- square foot building, lighting costs would be $24,500 annually. This annual lighting cost is for the average building, however in other applications, energy consumption for lighting is far higher.
Are there any real solutions???
Just have a look at the brief research work from CBM
We will look forward to hear back your thoughts

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.
Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.
2. Introduction
India is facing significant growth in electricity demand and could benefit greatly
by using energy efficient lighting systems. The need of the hour for the country is
secured, affordable and environmentally sustainable energy to meet the
ambitious National Programme of “Power to all by 2012”.
Lighting is the most visible form of electricity consumption and lighting load in
our country is very high about 17-18% of total load. By increasing the efficiency of
lighting system, there can be significant energy saving and reduction in peak
load. There is a scope for reducing about 30 to 35 % of the morning and evening
peak demand.

3. Scheme for Promoting Energy Efficiency in India :
Bachat Lamp Yojana
The 'Bachat Lamp Yojana' aims at the large scale replacement of incandescent bulbs in households by CFLs. It
seeks to provide CFLs to households at the price similar to that of incandescent bulbs and plans to utilize the
Clean Development Mechanism (CDM) of the Kyoto Protocol to recover the cost differential between the
market price of the CFLs and the price at which they are sold to households.
The Bachat Lamp Yojana is designed as a public-private partnership between the Government of India, private
sector CFL suppliers and State level Electricity Distribution Companies (DISCOMs). The CFL suppliers would
sell high quality CFLs to households at a price of Rs. 15 per CFL within a designated project area in a DISCOM
region of operation. The CFL supplier will be chosen by the DISCOM through a due diligence process from a
list of CFL suppliers empanelled by BEE. Under the scheme, 40 watt, 60 Watt and 100 Watt incandescent
lamps will be replaced with 9-11 Watt, 13-15 Watt and 20-23 Watt CFLs respectively.

lighting energy by 70%.
• Use of mirror optic fluorescent lamps increases the lighting level considerably.
• Use of HPSV lamps in place of MPSV lamps reduce the energy consumption by
60%
• As the lighting level is inversely proportional to square of the distance, optimizing
the height of lamp will aid in reduction of lighting energy.
Prajit Kumar Datta - 11BEM0105 (prajitkumar.datta2011@vit.ac.in)
11. Energy Conservation Measures
in Lighting Systems Contd…
• Use of electronic ballasts for discharge lamps, reduce energy consumption by 20%
• Installation of intelligent lighting controller will help in controlling the lighting energy.
• Use of photo sensor switch for street light controlling helps in conserving the lighting energy.
• Installation of auto cut-off switch to put off lights during lunch
hours at the office buildings will reduce the lighting energy.
• At street lights, in many places, the reflectors inside the HPSV fitting are damaged, it is
suggested to replace the fittings with anodised aluminium reflectors. This will improve the
lighting level by 20-25%.
Prajit Kumar Datta - 11BEM0105 (prajitkumar.datta2011@vit.ac.in)
12. Why should people use CFLs?
• Switching from traditional light bulbs (called incandescent ) to CFLs
will help to use less electricity at home and prevent greenhouse gas
emissions that lead to global climate change.
• Lighting accounts for close to 20 % of the average home’s electric
bill.
• CFLs, last upto 10 times longer, cost little up front
• Provide a quick return on investment.
Prajit Kumar Datta - 11BEM0105 (prajitkumar.datta2011@vit.ac.in)
13. Do CFLs contain mercury?
• CFLs contain a very small amount of mercury sealed within the glass tubing - an
average of 4 milligrams .By comparison the older thermometers contain about
500 milligram of mercury – an amount equal to mercury in 125 CFLs .
• Mercury is an essential part of CFLs; it allows the bulb to be essential part of light
source.
• No mercury is released when bulbs are intact or in use .Most makers of light bulb
have reduced mercury in their fluorescent lighting products.
• Thanks to technology advances the average mercury content in CFLs has
dropped at least 20 % in the past year. Some manufacturers have even made
further reductions, dropping mercury content to 1.4-2.5milligrams per light bulb.
Prajit Kumar Datta - 11BEM0105 (prajitkumar.datta2011@vit.ac.in)
14. What precaution should take when using CFLs in
home?
CFLs are made of glass and can break if dropped or roughly
handled. Be careful when removing the bulb from packaging,
installing it, or replacing it. Always screw or unscrew the light bulb
by its base (not the glass ), and never forcefully twist the CFL into
light socket .If a CFL breaks in your home follow the clean up
recommendations given by Bureau of Energy Efficiency.
Prajit Kumar Datta - 11BEM0105 (prajitkumar.datta2011@vit.ac.in)
15. Key Product Features of CFLs
Low electrical consumption as compared to conventional
lighting products
About 80% energy saving over incandescent bulbs.
Long life up to 10,000 hours.
It can operate within 130-280 V range.
Low cost of maintenance.
High luminous efficiency.

Mercury content within the CFLs (Maximum Limit being
less than 5mg).
Prajit Kumar Datta - 11BEM0105 (prajitkumar.datta2011@vit.ac.in)
16. What is LED?
• LED is a light emitting semiconductor diode that emits light in
forward direction or in the direction it is pointed towards.
• LEDs are most often used in the form of an indicator light in
electronic devices, traffic signal lights, musical instruments and
dashboards in cars and in houses, etc.
• The color of the light produced by LED depends on the composition
of the semiconductor material used out of which producing a blue
color light is the most difficult process.
• The nature of the light emitted can be visible, infrared or ultraviolet.
Prajit Kumar Datta - 11BEM0105 (prajitkumar.datta2011@vit.ac.in)
17. Lifespan of a LED light bulb
• Most modern LEDs are undergo superior design and manufacturing process that
gives them a lifespan of up-to 1,00,000 hours, compared with 10,000 for a
compact fluorescent and 1,000 for an incandescent bulb.
• Lifespan of a LED bulb could come down due to the amount of heat a LED
produces. This directly depends on die temperature and ambient temperature of
the LED.
• Some LED light bulbs show sign of age after a couple of years of use and may
produce only 50% of the light output when compared to what it used to produce
when it was new. However new technologies are in process to enhance its
performance over its life span.
Prajit Kumar Datta - 11BEM0105 (prajitkumar.datta2011@vit.ac.in)
18. Power consumption of LED light bulbs
• Most modern LED operate in a range of 2 to 4 volts and consume
anywhere between 350mA and 1500mA. The power consumption
varies from manufacturer to manufacturer and also because of the
purpose for which the LED was designed.
• Another factor that affects power consumption of LEDs is for the
fact that LEDs can not be dimmed.
• Now a days using latest of the LED manufacturing technology,
manufacturers are able to produce LEDs that are not only super
bright but also consume less power while producing light of higher
intensity.
Prajit Kumar Datta - 11BEM0105 (prajitkumar.datta2011@vit.ac.in)
19. Benefits of using LED light bulbs over standard light bulbs
• Power consumption of LED light bulb is only 10% of the standard light bulb.
• LED light bulbs withstand great amount of vibration, shock and temperature variations.
• LED light bulbs are 10-60 times more energy efficient than incandescent light bulbs.
• Incandescent light bulbs produce light that flickers whereas LED light bulbs produce flicker free
light.
• LED bulbs can produce many rich and vibrant colors when compared to incandescent light bulbs.
Prajit Kumar Datta - 11BEM0105 (prajitkumar.datta2011@vit.ac.in)
20. Key Product Features of LED light bulbs
• Low electrical consumption as compared to conventional lighting products.
• Pollution free due to non-emission of infra red or ultraviolet
rays, mercury gases or other harmful rays.
• Do not have ballasts thus, no interference.
• Existing fixtures used since long are used making installation
of our lights easy.
