This document provides an overview of energy resources and conservation. It begins by defining energy and classifying resources as renewable and non-renewable. Fossil fuels like coal, oil and natural gas make up most of the world's energy consumption currently, though renewable sources like solar, wind and hydropower are growing. The document then discusses various non-renewable and renewable energy sources in more detail. It concludes by emphasizing the importance of energy conservation to use resources optimally and ensure availability for future generations.

3. 
Energy is the ability or the capacity to do work. It is
the source of power for mechanisms and organisms
without it nothing will work.
 Common sources of energy are fossil fuels like
coal, oil and natural gas. They are all nonrenewable sources and are naturally made from
decaying plants and animals that existed million
years ago.

4. ENERGY RESOURCES

1.
2.
The substances from which we produce energy are
known as energy sources. We need energy for our
day to day life.
Renewable source of energy
Non-renewable source of energy

5. WORLD ENERGY CONSUMPTION

Fossil fuels constitute most of the energy we use. Only
16.7% of the total energy is renewable energy.

6. NON-RENEWABLE ENERGY RESOURCES


The sources of energy that once used , cannot be
reused are known as non-renewable sources of
energy.
These are the energy sources which are found from
the earth crust. These sources of energy are known
as fossil fuels.
These took millions of years to form
Coal
Petroleum
Natural gas
Nuclear fuel

7. COAL
Coal is a hard, black, rocklike substance made up of
carbon, hydrogen , oxygen, nitrogen, and sulphur.
Lignite is the softest kind of coal. While anthracite is the
best kind of coal.

8. Coal is mined, may be1. Open pit mining
2. Underground mining
POWER PLANTS
Mining
Transportation
Pulverisation

9.  Petroleum, also known as crude
oil which is unprocessed oil from
underground reserves. It is Primarily
made up of hydro carbons.
Crude oil can be sources of different
by-products such as gasoline, kerosene
and diesel. It can also be refined to
create polymers that are used to make
plastics.
The Philippines has large reserves of natural gas , an
odorless and colorless chemical compound

10. RENEWABLE ENERGY SOURCES
Unlimited sources of energy which will not be exhausted
in any near future.
 About 16.7% of global final energy consumption comes
from renewable energy sources.
The renewable sources of energy include:
 Solar energy
 Hydel energy
 Wind energy
 Tidal energy
 Geothermal energy
 Biogas


11. SOLAR POWER


1.
2.
Solar power is the power derived from the rays of the sun.
Solar power can be used in two ways: Direct (warm water, solar cooker)
Indirect(solar cells or photo-voltaic cells)

12. HYDEL POWER
Hydel power is the energy generated
by rotating turbine by the flow of water.
Water is collected behind a dam and
then the water is allowed to flow to low
potential , by turning a turbine. It is a
clean source of power.

13. WIND ENERGY


wind turbines are set up in fast
flowing winds areas.
Globally wind energy contributes
0.51% to the global power
generation.
Limitations:
 Require huge amount of
unobstructed land.
 Constant wind flow throughout the
year, not seasonal.

14. GEOTHERMAL ENERGY

It is the energy obtained from the
Earth’s crust . Where there is
magma near the surface, cold water
is sent through a shaft to the heated
rocks and through another shaft,
steam is extracted which is used to
turn turbines to generate electricity.
Limitations:
 Geothermal energy can only be
used where the magma layer is near
the surface of the surface.

15. BIO GAS


Bio gas is based upon
the use of dung to
produce gas which is
used as domestic fuel
especially in rural
areas.
Decomposition of
organic matter in the
absence of air.

16. PARTICIPATION &USE OF ENERGY

17. ENERGY CONSERVATION
“Energy conservation means to reduce the quantity
of energy that is used for different purposes.”

Optimum Utilisation

Proper Management

This practice may result in
I.
Increase of financial capital,
II.
Environmental value,
III.
National and personal security
IV.
Human comfort.

It can be implemented in following fields-
a)
Residential sector
b)
Commercial sector
c)
Industrial sector
d)
Transportation sector

18. INDUSTRIAL & DOMESTIC FANS
Use light weight/high
power fans.
 Use electronic
regulators for less cost
 Avoid rewinding motors
 Clean fan blades often
 Oil in the fan bearings


19. AC IN INDUSTRIES & HOME






Select an appropriate size of the
AC unit according to the room
size.
Close the doors of the rooms.
Clean the filters of the AC
frequently
See that there is no air going out
of the room
Keep the AC always in 25 deg C.
When you replace your old AC
always look for AC with Star
mark for better power and
energy.

20. MOTOR PUMPS IN INDUSTRIES



Use high power motor
pumps for efficiency
Avoid water leakages
in the pipes
Add capacitors in the
water pump motor

21. COMPUTERS IN OFFICES




When not in use switch off computers.
Sleep mode computers/monitors
save 40% power
Switching on/off of the PC according
to requirement saves power and
provides extension of life to PCs as
well.
use lcd monitor

22. WATER HEATERS IN INDUSTRIES & HOME




Avoid leakages in the
water pipes
Try solar heaters if possible
Try to put on safety cover
on to hot water pipes…
Proper insulation

23. REFRIGRATORS






Always keep the Fridge little away from
the wall and let there by some
ventilation.
Avoid frequent opening and closing of
doors
Avoid keeping hot/warm products in the
fridge
Defrosting.
Buy “Star” marked fridges for power
save
Adjust the thermostat instrument of the
fridge according to the room or outside
temperature

24. GRINDER AT HOME




Use high power motors in the grinders
See that your grinders have nylon belts
Use the grinder to the full power and
energy
Clean the grinder often and apply oil
in relevant parts.
Try and plan for more clothes
at a time.
Switch off the Iron when not
in use

25. CONCLUSION



Optimum utilization of resources
The renewable sources of energy should be modified to give
the maximum output.
Improvement of engines design.The engines should be made
more efficient.
And last but not the least……

“Save electricity and fuel for the future.”
