3. INTRODUCTION Energy Energy is capacity to do work . Energy can be changed from one form to another but it neither be created nor be destroyed. Energy Resources An energy resources is something that can produce heat, power life , move objects ,or produce electricity .matter that store energy is called fuel .

4. CLASSIFICATION

5. RENEWABLE ENERGY RESOURCES The sources of energy which are renewed again to again at a faster rate in nature are known as renewable energy resources. Example – Solar Energy , Wind Energy , Hydro Energy ,Biomass Energy.

6. RENEWABLE ENERGY RESOURSES SOLAR ENERGY Solar energy is available in large amount, because ultimate sources of energy in an ecosystem is sun . Thus considered major future sources of energy . it is incident on green plants , they carry out photosynthesis in the presence of CO2 , water and sunlight and make their own food ,thus maintain life . Their death produces biomass . Example – Solar light

8. Photovoltaic cell is phenomenon that conversion of solar energy to electricity. Photovoltaic cell

9. HYDRO ENERGY Water is made to fall from height to rotate turbine, which help generate electricity ,is known as hydro energy. APPLICATION Hydro power use the energy for moving water for a variety of useful application , hydroelectricity generates electricity by the gravitational force of falling water . It use water in dams to drive turbines and generates which turns Mechanical energy into Electrical energy.

11. WIND ENERGY Wind is allowed to rotate the blades of wind mills , which rotates turbines to generate electricity. APPLICATION The wind is a free clean and in exhaustible energy sources . It has served human kind well for many centuries by propelling ships and driving ,wind turbines to grind grain and pump water . DENMARK was the first country to use wind for generation of electricity.

13. BIOMASS India is an agriculture based country .Agriculture and dairy farming produced large amount of biomass. Example – Agricultural waste and Cow Dung Dead organic matter or dead plant and animal parts are known as Biomass. Example- wood , leaf parts and crop residue .

15. NON RENEWAABLE ENERGY These energy resources are formed inside the earth crust at very high temperature and pressure ,take a very long passage of time in their formation .Thus they are present in limited amount in nature’s reservoir. Example – coal , petroleum , natural gas , timber , nuclear fuel. These included two types of energy resources - Fossil fuel, Nuclear Energy.

16. FOSSIL FUEL Fossil fuel are found inside the earth crust where they have formed through heat and compression of forest waste and other organic matter, which got buried due to Earthquake and landslide etc. CLASSIFICATION OF FOSSIL FUEL Solid ( Coal ) Liquid ( Petroleum ) Gaseous ( Natural gas )

17. COAL Coal is the most abundantly found fossil fuel in the world .It contain Carbon , Water , Sulphur , and Nitrogen . Coal meets 70% of the total energy needs of the world around. It is used for cooking , industry, and thermal power plant.

18. PETROLEUM Petroleum is a natural underground fossil energy resources . It is formed due to decomposition of micro plankton deposited upon the sea beds, lakes , and river for millions of years . The decomposition takes place by the action of bacteria under lack of O2 , called crude oil .

19. NATURAL GAS It is a mixture hydrocarbon gases trapped under the earth surface. It is a mainly consisting of methane (CH4) ,Propane (C3H8) , and Butane (C4H10) . Natural gas can used in two different forms - LPG – ( Liquefied Petroleum Gas ) CNG – ( Compressed Natural Gas )

20. NUCLEAR ENERGY It present nuclear power . It is a highly developed alternative far energy production in place of coal. Nuclear energy can divided by two processes - NUCLEAR FISSION NUCLEAR FUSION

21. NUCLEAR FISSION The heavy nucleus on bombardment with neutron splits into lighter nuclei (Barium and krypton ) releases large amount of energy .one amu of U235 yield energy equal to burning of 15 metric tons of coal.

22. NUCLEAR FUSION Nuclear fusion is a reaction in which two or more atomic nuclei come close enough to form one or more different atomic nuclei and subatomic particles (neutrons and / or protons ) .The difference in mass between the products and reactants is manifested as the release of large amounts of energy.

23. IMPORTANCE IN INDIA In India there are still thousand of villages where darkness is not dispelled by electricity . These villages due to their remote location are not likely to have access to electricity supply from the grid for a very long time. In the rural areas ,domestic energy consumption especially for cooking , constitutes a significant part of energy demand .

24. MY VIEW Human energy consumption has grown steadily throughout human history . Early human had modest energy requirement. Most ly food and fuel for fires to cook and keep warm . In today’s society human consume as much as 110 times as energy per person as early humans . In any event the exploitation of all energy sources ultimately rely on material on planet earth.
