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

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

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.
8/12/2019 EnergyConservation Presentation

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.
The only solution is ..

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

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.

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

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

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.

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.
