2. What are Natural Resources ?
♣ Natural Resources come from nature and are used or turned
into the things that we want and need to live.
♣ Natural Resources provide us with the things we need such
as air, water and food, as well as things we may want such
as television, toys etc…

TYPES OF NATURAL
RESOURCES

4. RENEWABLE RESOURCES
These resources are capable of being regenerated by ecological processes
within a reasonable time period.
EXAMPLES:
Soil
Water
Air
Wildlife

5. NON-RENEWABLE RESOURCES
 These resources are not capable of being regenerated by
ecological process.

8. Significance of solar energy:
 Solar cells are noise and eco- friendly.
 Solar water heaters, cookers, require
neither fuel nor attention while cooking
food.
 Solar cells can be used in remote and
isolated areas, forests and hilly regions.

9. WiND ENERGY:
 Wind energy is harnessed by
making use of wind mills.
Energy recovered from the force of the wind is called wind
energy.
China has the world’s
largest onshore wind
farm with a capacity of
7,965 megawatt
(MW), which is five
times larger than its
nearest rival.

10. Significance of wind energy:
• The generation period of
wind energy is low.
• It is made available easily in
many off-shore, on-shore
and remote areas

11. bIOMASS ENERGY:
 Biomass energy is generated or produced by living or once-living
organisms.
 Biomass is the organic matter, produced by plants or animals, used as
sources of energy.
 Most of the biomass is burned directly for heating, cooling and industrial
purposes
TCP PRESENTO 2020, THIAGARAJAR COLLEGE OF PRECEPTORS, MADURAI.

12. Significance of Biomass energy:
o Biomass consumes more carbon-di-
oxide than is released during
combustion of biomass.
o The cost of obtaining bio-energy
through bio-gas plant is less than the
cost of obtaining energy from fossil
fuels.
o Large amount of energy is expended
in the cultivation and processing of
crops like sugarcane, coconut, and rice
which can met by utilizing energy-rich
residues for electricity production.

13. TIDAL ENERGY:
Tidal power or tidal energy is the form of hydropower that
converts the energy obtained from tides into useful forms of
power, mainly electricity.
TCP PRESENTO 2020, THIAGARAJAR COLLEGE OF PRECEPTORS, MADURAI.

14. Significance of tidal energy:
 Tidal power plants do not require
large areas of valuable lands.
 It is a pollution- free energy
source, as it doesnot use any fuel
and also does not produce any
wastes.

15. hydroelectric ENERGY:
Hydroelectric energy is a
form of renewable energy that uses
the power of moving water to
generate electricity.
TCP PRESENTO 2020, THIAGARAJAR COLLEGE OF PRECEPTORS, MADURAI.

16. Significance of hydroelectric energy:
 This is a domestic source
of energy, allowing each state to
produce their own energy without being
reliant on international fuel sources.
 Hydroelectricity is very reliable
energy.
 Compared to among other fossil
fuels and nuclear energy, hydroelectricity
is much safer.

19. Forests !!! How are they useful ?????
Forests are habitats to millions of plants,
animals and wildlife.
 They control water quality and quantity.
 They moderate temperature and weather and
help to maintain humidity.
 They prevent soil erosion and perform
watershed functions.
 They promote tourism.

20.  All living things require water to grow
and reproduce.
 97% of the water on the Earth is salt
water and only three percent is fresh
water; slightly over two thirds of this is
frozen in glaciers and polar ice caps.
 The remaining unfrozen freshwater is
found mainly as groundwater, with only
a small fraction present above ground
or in the air.

21. Let us know
70% of the
human brain
is water. ...
Unsafe water
kills 200
children every
hour. Water
expands by
9% when it
freezes.

22. Conclusion:
Since resources are being exhaustible, it is the duty of every
individual on this earth to conserve the natural resources in such a
way that they must be available for future generation also. Individual
must understand the essential of natural resources. So let us join
hands to save our earth.
