What is Energy
Classification of Energy Resources
Energy Consumption in Total World
Brief Explanation of Each
Participation & Use of Diff. Type Of Energy
What is Energy Conservation?
Energy Conservation in Different Areas.
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
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
WORLD ENERGY CONSUMPTION
Fossil fuels constitute most of the energy we use. Only
16.7% of the total energy is renewable energy.
NON-RENEWABLE ENERGY RESOURCES
The sources of energy that once used , cannot be
reused are known as non-renewable sources of
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 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.
Coal is mined, may be1. Open pit mining
2. Underground mining
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
The Philippines has large reserves of natural gas , an
odorless and colorless chemical compound
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 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)
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.
wind turbines are set up in fast
flowing winds areas.
Globally wind energy contributes
0.51% to the global power
Require huge amount of
Constant wind flow throughout the
year, not seasonal.
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.
Geothermal energy can only be
used where the magma layer is near
the surface of the surface.
Bio gas is based upon
the use of dung to
produce gas which is
used as domestic fuel
especially in rural
organic matter in the
absence of air.
“Energy conservation means to reduce the quantity
of energy that is used for different purposes.”
This practice may result in
Increase of financial capital,
National and personal security
It can be implemented in following fields-
INDUSTRIAL & DOMESTIC FANS
Use light weight/high
regulators for less cost
Avoid rewinding motors
Clean fan blades often
Oil in the fan bearings
AC IN INDUSTRIES & HOME
Select an appropriate size of the
AC unit according to the room
Close the doors of the rooms.
Clean the filters of the AC
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
MOTOR PUMPS IN INDUSTRIES
Use high power motor
pumps for efficiency
Avoid water leakages
in the pipes
Add capacitors in the
water pump motor
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
use lcd monitor
WATER HEATERS IN INDUSTRIES & HOME
Avoid leakages in the
Try solar heaters if possible
Try to put on safety cover
on to hot water pipes…
Always keep the Fridge little away from
the wall and let there by some
Avoid frequent opening and closing of
Avoid keeping hot/warm products in the
Buy “Star” marked fridges for power
Adjust the thermostat instrument of the
fridge according to the room or outside
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
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
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
And last but not the least……
“Save electricity and fuel for the future.”
