    ENERGY & ITSCONSERVATION

    EnergyEnergy can neither be generated nor it can

    be destroyed. It can only be converted from

    one form to another.

    For example, in a room heater, electrical

    energy is converted to the thermal energy.

    Turbine converts mechanical energy stored

    in steam to electrical energy.Energy is in everything. We use energy for

    everything we do, from making a jump shot

    to baking cookies to sending astronauts intos ace.

    Energy can be broadly divided into two

    categories:-

    1. Renewable Energy

    2. Non Renewable Energy

    Types of Energy

    5/47

    Renewable energy can be generated continuously

    practically without decay of sources of energy. E.g.-

    Solar Energy Wind Energy

    Geothermal Energy

    Hydro Energy

    Renewable Energy

  • 8/12/2019 EnergyConservation Presentation

    Solar Energy

    Solar energy can beconverted into electrical

    energy by using solarpanels, or alternatively, beused as thermal energyusing solar water heaters,solar cookers etc.

    Wind Energy

    India is worlds

    third largest

    producer ofelectricity

    generation using

    wind power bywind mills.

    Hydro EnergyUsing dams, water is

    allowed to passthrough turbineblades, whichproduces electricity.In India, after coal,

    most of the energy isproduced by thismethod.

    Non RenewableNon renewable

    energy cannot be

    generated again andagain, e.g. energy

    generated from

    combustion of fossil

    fuels, energy from

    coal and gas etc.

    Why to Conserve?We have limited fuelsavailable on earth.

    Our demand for energy isincreasing day-by-day.

    It is possible that someday,most of fuels will be

    exhausted, and we willhave to switch over toalternate energy.

    Limited FuelsAt present consumption levels-

    Crude oil will last only for 40 years.

    Coal will be finished in nearly 200 years.

    Gas will last for 60

    Consumption

    Furthermore, our consumption is

    increasing day-by-day.

    This means fuels will last much earlier

    than expected.

    Energy Conservation

    Energy conservation is

    the reduction in theamount of energy

    consumed in a process or

    system, or by anorganization or society,

    through rational use and

    reduction of waste.

    Star RatingsBEE has also initiated

    Star Rating System for

    electrical appliances e.g.

    refrigerator, CFL, geysers

    etc. In this system, 1-5 stars

    are allotted to products

    depending on their energyefficiency. A five star

    product means that it

    consumes least energy in

    its segment.

    At HomeTell family to take material out from fridge if

    it is to be heated, some time earlier so that

    cooking gas consumption is low.

    We should not open fridge door frequently.Watching interesting programs on TV is

    interesting, but afterwards, TV should be

    switched off.

  • 8/12/2019 EnergyConservation Presentation

    31/47

    At HomeWhile going to purchase new products, e.g.

    refrigerator, geysers, CFL etc., we should

    insist upon purchasing a five star product

    rather than cheap and energy waster product.

    Have your car tunedregularly.

    Keep your tires properlyinflated.

    Avoid lengthy engine idling.

    When you buy a car,

    choose one that gets goodmileage.

    Pace your driving.

    At Home

    33/47

    In OfficeAlways switch off lights and fans while

    going out of the office.

  • 8/12/2019 EnergyConservation Presentation

    34/47

    In OFFICE In Office computer , we should switch off

    computers before going out of office.

  • 8/12/2019 EnergyConservation Presentation

    35/47

    In OFFICE Switching off non-essential overhead lighting in day-lit areas

    and lighting in unoccupied rooms (e.g. equipment and storageareas)

    Switching off monitors, printers and other excess electricalequipment after work hours and break timing.

    Checking and cleaning of air conditioner filters and chillers on

    a scheduled basis.

    Using sunlight and less of artificial lighting.

    Using translucent ceiling in retail outlets.

    Double-side printing: Saving paper saves energy because it takes10 times more energy to manufacture a piece of paper than it does toput an image on it.

    Energy Star models: When purchasing PCs, monitors, printers, faxmachines and copiers, look for Energy Star models.

    If appropriate, use ink-jet printers - they consume 95% less energythan laser printers. Similarly, laptops use 90% less energy than

    desktop computers.

    In OFFICE

  • 8/12/2019 EnergyConservation Presentation

    37/47

    Training and awareness sessions

    should be organized for employees onenergy conservation.

    Turn off all personal office appliancesincluding fans, radios and desk lamps

    Enable power management featureson laser printers and/or turn laserprinters when not actively printing.

    In OFFICE

  • 8/12/2019 EnergyConservation Presentation

    38/47

    Replace desktop PCs with laptops.Save paper. Photocopy only what you

    need.

    Have a qualified professional performan energy audit. Check with yourcompany for names of auditors.

    There should be facilities managementsservice systems that can respondimmediately to facilities andenvironmental problems.

    What have we learnt ?

    Energy does work.

    Energy is never used up it is simply

    converted from one form to another.

    Fuels and food are sources of energy.

    There are 3 main classes of fuel which can

    be used to generate electricity: Fossil

    fuels, renewable fuels and nuclear fuels.

  • 8/12/2019 EnergyConservation Presentation

    40/47

    Fossil fuels such as gas, coal and oil and

    renewable fuels such as wood are burnt

    and heat is generated. This heat is used to

    boil water and the steam that is created is

    used to turn large propellers called

    turbines. These turbines then turnelectrical generators, produces electricity.

    There are other sources of energy such as:Solar power, wind power, hydroelectric

    power and wave power.

    ConclusionTo make sure we have plenty of energy in the

    future, its up to all of us to use energy wisely.

    We must all conserve energy and use itefficiently.

    Its also up to those who will create the new

    energy technologies in the future.

  • 8/12/2019 EnergyConservation Presentation

    42/47

    THE FUTURE IS IN

    YOUR HANDS!

  • 8/12/2019 EnergyConservation Presentation

    43/47

    How will it help?Take an example:

    We replace one 100W bulb with a 13W CFL.

    Let us assume electricity is available for Rs.

    3.00 per unit, and this bulb is used for 6

    Hours a day.

    The annual saving would be.

  • 8/12/2019 EnergyConservation Presentation

    44/47

    Power SavingPower saved: 100W-13W = 87W

    =87W X 6 Hours X 365 Days

    =17520 WH

    =17.520 kWH or Units

    =Rs. 52.56

    Say Rupees 50 per one bulb replaced.

  • 8/12/2019 EnergyConservation Presentation

    45/47

    So,Remember to replace light bulbs with CFLs

    so electricity could be available for more

    time.You can also get a money saving after

    reducing your electricity bill.

  • 8/12/2019 EnergyConservation Presentation

    46/47

    What Else can be Do?

    We should discuss energy conservation with

    our friends and tell others how can we reduce

    energy consumption.
