2. Mother Earth—Our Home
It has Water , Oxygen & Hospitable Climate

4. Our fossil Fuels
Are Running Out?

5. We are Now moving toward’s
End of Energy & Earth

6. Now its time to stop using fuels & save the
world But without fuel how will the life run?
At this time nature comes to our help that is:
Renewable energy

7. Renewable Energy:
 Solar energy
 Wind Energy
 Thermal Energy
 Energy From Biomass
 Hydrogen Energy
 Energy from ocean

8. Solar Energy
 Every Day the world Recieves an amount of solar
energy equal to 30 years of world fossil fuels
 In half a day the US recieves the same amount of
energy from sun that it consumes for all purposes for
entire year.
 Solar energy can Heat buildings, cook food , drive
pumps & refrigerators , &make electricity.

9. Sources & uses in India
 There are 300 clear sunny days in India on an Average.
 A potential of 30 MW per sq.km in India but still we
are not using its 50% also.
 Maximum efficiency possible is below 30%.but
CNT(Carbon Nano Tube)based PV cells hold promise
of higher efficiency having 35% at present which is still
not sufficient for economical .

10. Wind Energy
 India has got a potential of obtaining 20000MW power
from wind but today we are using only7000MW power
from wind.
 There is an advantage of Shorter Gestation period.

11. Energy from Biomass
 Overall biogas potential about 19000MW.
 India is a largest producer of Sugarcane.
 Power from bagasse is of 3500MW current capacity of
around 425MW ,under construction 480 MW.

12. Chart Showing Use of energy:
coal
oil
gas
Nuclear
Renewable

13. Conclusions:
 From Chart we can See That today we are using Coal a
lot which is going to be over in our near times.
 Our future childrens are going to suffer due to us.
 We should try to make more projects on renewable
energy & help Save Earth.
