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. Types of 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. A dvantages : 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 . T he turbines may create a lot of noise. Threat to wildlife in remote locations.

12. Tidal energy  T idal 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 CO 2 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 Of energy 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-Conventional Sources 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.....
