conventional and non conventional source of energy
- 1. “Conventional & non conventional Sources of energy“ BINA MAM
- 5. 1 . VERY LARGEAMOUNT OF ENERGY CAN BE GENRATED IN A PLACE USING COAL FAIRLYCHEAPLY . 2. TRANSPORTING OIL AND GAS TO POWER STATIONS IS EASY . 3 . GAS – FIRED POWER STATIONS ARE VERY EFFICIENT . 1 . BURNING OF FOSSIL FUEL CAUSES AIR POLLUTION . 2 . GREENHOUSE GASES LIKE CO2 ARE RELEASED ON BURNING FOSSIL FUELS . 3 . FOSSIL FUELS ARE NOT BURNT COMPLETELY . THEY LEAVE ASHES AFTER BURNING .
- 6. IN THERMALPOWER PLANTS , FUEL IS BURNT TO PRODUCE HEAT ENERGY WHICH IS CONVERT INTO ELETRICAL ENERGY . LARGEAMOUNT OF FOSSIL FUELS ARE BURNT IN POWER STATIONS TO HEAT UP WATER TO PRODUCE STEAM WHICH FURTHER RUNS THE TURBINE TO GENERATE ELECTRICITY .
- 9. 1 . No environmentalpollution. 2 .Constructionof dams helps in controlling flood and irrigation. 3 . The cost is less. 1 .Constructionof dams lead to ecological damage. 2. Decreases soil fertilityin the down stream area. 3. Creates theproblem of rehabilitationof displaced people. 1 . No environmentalpollution. 2 .Constructionof dams helps in controlling flood and irrigation. 3 . The cost is less.
- 11. BIO GAS
- 12. 1 . IT BURNSWITHOUTSMOKE, THEREFORECAUSES LESS POLLUTION. 2 . ITS CALORIFICVALUE IS HIGH . 3 . IT IS CONVENIENTTOUSE AND LEAVE NORESIDUE . 1 . IT IS USED FORGENERATING ELECTRICITY. 2 . IT IS USED TORUNENGINES AND PUMPINGSETS . 3 . IT IS ANDOMESTICFUEL FOR COOKINGAS WELL AS IN INDUSTRIES.
- 14. 1 . IT IS ANENVIROMENT–FRIENDLY AND EFFICIENTSOURCESOFRENEWABLE ENERGY. 2 . IT REQUIRESNO RECURRINGEXPENSES FOR THE PRODUCTIONOF ELECTRICITY. 3 . IT DO NOTCAUSESPOLLUTION. DENMARK IS CALLED COUNTRY OF WINDS. MORE THAN 25 % OF THEIR ELECTRICITY NEEDS ARE GENERATED THROUGH A VAST NETWORK OF WINDMILLS.
- 16. Alternative energy sources are inexhaustible and are thought to be "free" energy sources. They all have lower carbon emissions, compared to conventional energy sources. These include Solar Energy, Geothermal Energy , wave energy Etc.
- 17. ITIS THE ENERGY FROMTHE SUN. IT PROVIDESALL OF US HEAT AND LIGHT . SOLAR RADITIONSMOSTLYCONSISTOF 1 . ULTRAVIOLETRAYS 2 . VISIBLE RAYS 3 . INFRAREDRAYS.
- 19. Due to attraction of moon on sea water ,water surface rise and falls, thus the waves are formed, these waves are called tidal wave . And energy possessed by rising and fallingwater tides known as tidal energy .
- 20. DUE TO BLOWING OF WIND ON THE SURFACE OF OCEAN VERY FAST SEA WAVES ARE GNERATED . WHICH HAVEA LOT OF KINETIC ENERGY IN THEM . THIS ENERGY , WITH THE HELPOF VARIOUS DEVICES CAN BE USED TO ROTATE THE TURBINE OF GENERATOR AND ELECTRICITY IS GENERATED .
- 21. THE HEAT FROM INTERIOR OF THE EARTH CAN BE UTILISED AS A SOURCE OF ENERGY UNDER CERTAIN FAVORABLECONDITION THAT ARE CREATED BY NATURAL PROCESSES . THIS IS KNOWN AS GEOTHERMAL ENERGY . IT IS ONE OF THE SOURCE OF ENERGY WHICH DO NOT COME DIRECTLY OR INDIRECTLY
- 22. ENERGY CONTAINED IN THE NUCLEUS OF ATOMS IS CALLED NUCLEAR ENERGY . IT IS RELEASED DURING NUCLEAR REACTION . A REACTION IN WHICH COMPOSITION OF THE REACTING NUCLEI CHANGES TO FORMNEW ELEMENTS WITH A SIMULTANEOUS RELEASE OF LARGEAMOUNT OF ENERGY IS CALLED A NUCLEAR REACTION .
- 25. Fossil fuels are the major sources of conventional energies. At present, many countries are overly dependent on fossil fuels to meet their requirement for power. The known reserves of fossil fuels have depleted to a large extent due to its continued use. If it continues, there is risk of complete exhaustion of these sources of energy.
- 26. Nuclear energy plants need to be implemented with proper caution and care. Any accidental leakage in nuclear power plants may lead to severe hazardous condition. will have to focus on alternative energy sources, especially renewable energy sources, and make them more effective.
