4. What Is Energy ?
Energy is defined as capability to
do work.
 Energy is required to do anything
 Energy has many forms.
 It can be changed from one form07/03/2014 4SOURCES OF ENERGY

6. Fossil Fuels - COAL
• Scientist believe that coal was made
from the remains of plants.
• The energy obtained by the burning
of coal is more that of wood
• Coal mainly consists – Carbon
• It also consists of –
Hydrogen, Oxygen, Nitrogen, Sulphur.

7. Fossil Fuel
• A long time ago, plants animal got
buried into the earth. Due to the
effect of tremendous pressure by the
layers of Earth above and heat inside
the earth the got converted into fuels.
• It takes lakhs of years for fossil fuel
to be formed.
• Fossil fuel are found in three form-
Solid
Liquid
gaseous

8. FOSSIL FUEL – NATURAL
GAS
• It also forms like the Mineral Oil
• It consists mainly methane (95%) with
small quantities of ethane and
propane(5%).
• It burns without any residue
• Also it does not produce any smoke

10. Fossil Fuel – Mineral Oil
• Mineral Oil is found nearly 25,000 meters
deep in the bowels of the earth.
• Mineral oil is also called as ‘Petroleum’ or
‘Crude Oil’.
• Petrol , Diesel , kerosene , Bitumen are
some of the products of petroleum.

12. RENEWABLE RESOUCES
• Renewable energy is generally defined
as energy that comes from resources
which are naturally replenished on a
human timescale such
as sunlight, wind.
• In simple word, Renewable Resources
are those resources which are
unlimited.

13. 1. Solar Energy
• Solar Energy is used since thousand
years in different ways like: cooking
, drying, heating and now for
electricity generation
• It is also used in space where there
is no other energy source
• Solar energy is energy that is present
in sunlight.
• It is cheaper to make electricity by
solar energy rather than coal and07/03/2014 13SOURCES OF ENERGY

15. 2. Wind Energy
• Wind power is the conversion the energy
of wind into a more useful form of
energy, like electricity.
• The wind has kinetic energy (movement
energy) which is changed into mechanical
energy by the blades on the turbine. The
turbine then turns a generator which
creates electrical energy (voltage)

17. Non Renewable Resources
• A non-renewable resource is a natural
resource that is used up faster than it can be
made by nature.
• It cannot be produced, grown or generated on
a scale which can sustain how quickly it is
being consumed.
• Once it is used up, there is no more available
for future needs
• For e.g. :-Coal, Natural Gas ,Mineral Oil

18. Atomic Energy
• Atomic Energy is the Energy produced by the
bombarding of the uranium atoms.
• The heat and energy produced by this is then
converted into electricity.

19. Conclusion
• Energy is required to do any thing.
• Resources are limited so we should use it
carefully
• We should use more solar and wind energy
than fossil fuels.
