India relies heavily on conventional energy sources and needs to develop non-conventional energy sources to meet growing demand. Non-conventional energy sources include solar, wind, tidal, geothermal, and biomass energy. These sources have advantages like being renewable, pollution-free and able to power remote areas, but also have disadvantages like high initial costs and intermittent availability. Developing non-conventional energy is necessary to secure India's long-term energy supply as fossil fuel prices rise and reserves are depleted. The potential for non-conventional energy in India is estimated to be around 95,000 MW.

4. Introduction
India ranked sixth in the world in total energy consumption . India
has installed power capacity from 1262 megawatt to over 112.058
megawatt this achievement is impressive but not sufficient .
So we mostly needed renewable sources of energy i.e non-
conventional sources that are continuously replenished by natural
processes .

5. Typesof non-conventional sources
 Solar Energy
 Wind Energy
 Tidal Energy
 Geothermal Energy
 Biomass Energy

6. Solar energy
The sun provides us enormous amounts of energy in the form of
solar radiation – energy that travels in small wave packets called
photons. Solar energy can be used in production of heat , electricity ,
bio-energy etc. .
There are some simple devices using solar energy like solar cooker ,
solar water heater , photovoltaic technology , solar cells etc.

7. Advantages :
 Solar energy is an immaculate and renewable energy source.
 Once a solar panel is installed, solar energy can be produced
free of charge.
 Solar energy causes no pollution.
 Provide electricity to remote places.

8. Disadvantages:
 Therefore, the intermittency and idiosyncrasies of solar
energy make solar panels a less reliable a solution.
 Solar panel efficiency is generally low (between 14%-25%).
 High Maintenance Cost.

9. Wind energy
Wind energy is a form of solar energy . Wind energy describes the
process by which wind is used to generate electricity. Wind turbines
convert the kinetic energy in the wind into mechanical power. A
generator can convert mechanical power into electricity.
Areas with constantly high speed preferably above 20km per
hour are well suited for harnessing wind energy.

10. Advantages:
Wind is free , wind farms need no fuel.
Good method of supplying energy to remote areas.
Wind energy is friendly to the surrounding environment because
it produces no waste & Green house gases.
Very low maintenance cost.
Land used for wind farms can also be used for other profitable
activities(i.e farming & foresting).

11. Disadvantages :
 Wind turbines do not produce the same amount of electricity
all the time.
 The turbines may create a lot of noise.
 Threat to wildlife in remote locations.

12. Tidalenergy
Tidal energy is a form of hydropower that converts the energy
obtained from tides into useful forms of power, mainly electricity.
The world's first large-scale tidal power plant was the Rance Tidal
Power station in France, which became operational in 1966.

13. Advantages:
 Environment-friendly.
 Highly predictable energy source.
 High energy density.
 Operational and maintenance costs are low.
 Inexhaustible source of energy.

14. Disadvantages:
 High tidal power plant construction costs.
 Negative influence on marine life forms.
 Location limits.
 Variable intensity of sea waves.

15. Geothermal energy
Geothermal energy is thermal energy generated and stored in
the earth. Thermal energy is the energy that determines the
temperature of matter. The geothermal energy of the earth’s
crust originates from the original formations of the planet and
from radioactive decay of materials .

16. Advantages:
 Geothermal energy is free and abundant.
 It reduces our reliance on fossil fuels.
Geothermal energy is very efficient and long lasting.
It does not cause pollution.

17. disAdvantages:
 Source is close to volcanic activity.
 Some plants use lots of water-creating water pollution.
 This cannot be transported.
 High start up cost.

18. Biomass energy
Biomass is the organic matter that originates from plants, animals,
wood, sewage waste. These substances burn to produce heat
energy which then generates electricity. The residue left after the
removal of biogas is a good source of manure. Biomass is an
important energy source contributing to more than 14% of the
global energy supply.

19. advantages:
It is a clean , renewable source of energy.
It does not release additional CO2 in to the atmosphere.
It utilizes waste material.
The availability of biomass fuels is universal.

20. Disadvantages:
 Expensive to make
 Haven’t found ways to store the energy.
 Also requires more fuel.
 Harmful to the environment.
 Requires more land.

21. Why do need non-conventional source Ofenergy
As the consumption of energy grows, the population depends
more and more on fossil fuels such as coal, oil and gas day by
day. There is a need to secure the energy supply for future since
the prices of gas and oil keep rising by each passing day. So we
need to use more and more renewable sources of energy.

22. Needs For Non-ConventionalSources Of Energy
 The non-conventional sources of energy are abundant in nature.
According to energy experts the non-conventional energy potential
of India is estimated at about 95,000 MW .
 These are renewable resources. The non-conventional sources of
energy can be renewed with minimum effort and money.
 Non-conventional sources of energy are pollution-free and eco-
friendly.....
