4. Non Conventional Energy Source
Solar Energy
Wind Energy
Tidal Energy
Geothermal Energy
Biofuel Energy
Biogas Energy

5. Solar Energy
Energy obtained from the sun in the form of
heat and light.
Solar cell
 Solar Heater
 Solar cooker

6. Use : Generating Electricity
Solar / Photo voltaic Cell

7. Single Solar Cell
 0.5 to 1 V
 0.7 W
Transmission

8. Wind Energy
 Wind is used to generate
mechanical power or electricity.
 The uneven heating of the
atmosphere by the sun

9. Wind mill TRANSMISSION

10. Tidal energy
ENERGY OBTAINED FROM TIDES
1.Tidal Barrage
2.Tidal Stream Generators
3.Tidal Lagoon

11. Tidal barrage
Ebb
Generation
 Flood
Generation
Two-way
Generation

12. Geothermal Energy
Greek words
Ge (earth) and thermos (hot).
Energy obtained from heat inside the earth.

13. Geothermal Plant Working

14. Biogas
It is produced by anaerobic degradation of animal
waste.
Methane (CH4), Carbon dioxide (CO2) ,
small hydrogen sulphide (H2S), moisture
and siloxanes.
 Floating gas holder
Fixed dome

15. Working of biogas plant

16. Biofuel
Biofuels derived from biomass.
 Solid biomass
Liquid biofuels -bio alcohols, such as bioethanol, and
oils, such as biodiesel.
Gaseous biofuels- biogas, landfill gas and synthetic
gas .
 Biofuels provided 2.7% of the world's transport fuel
in 2010.

17. Bioethanol
 It is an alcohol made by fermenting the sugar
components of plant materials and it is made
mostly from sugar and starch crops.
used as a fuel for vehicles in its pure form.
used in the USA and in Brazil.

18. Biodiesel
 Biodiesel Is Made From Vegetable Oils , Animal Fats Or Recycled Greases
 Biodiesel Is Produced From Oils Or Fats Using Trans Esterification whereby
the glycerin is separated from the fat or vegetable oil
 The process leaves behind two products – methyl esters and glycerin Methyl
esters is the chemical name for biodiesel
 Mostly Used in European countries

19. Advantages
Inexhaustible sources
Widely accepted by the general public
 Low operating costs
Renewable source
 Alternative for fossil fuels
 Low-maintenance

20. Disadvantages
Inconsistent, Unreliable Supply
Harmful to Wildlife and Surrounding Environment
High Cost
Location-Specificity
Low Efficiency Levels
