SOURCE OF ENERGY

WHAT IS A  GOOD SOURCE OF ENERGY ?

WE, IN OUR DAILY LIVES , USE ENERGY FROM DIFFERENT SOURCE FOR DURING WORK . WE CONSUME DIESEL TO RUN OUR TRAINS . WE USE ELECTRICITY TO LIGHT OUR STREET- LAMPS . WE USE ENERGY IN OUR MUSCLE FOR RUNNING CYCLE TO SCHOOL .

THE MUSCULAR ENERGY FOR DOING PHYSICAL WORK, ELECTRICAL ENERGY FOR RUNNING DIFFERENT APPLIANCES , CHEMICAL ENERGY FOR COOKING FOOD OR RUNNING A VEHICLE ALL COME FROM SOME SOURCE .

CONVENTIONAL SOURCE OF ENERGY - 

1) FOSSIL FUELS - 

                                 WOOD WAS THE MOST COMMON SOURCES OF HEAT ENERGY. THE ENERGY OF FLOWING WIND AND WATER WAS ALSO USED FOR LIMITED ACTIVITIES. THE EXPLOITATION OF COAL AS A  SOURCE OF ENERGY MADE THE INDUSTRIAL REVOLUTION POSSIBLE . INCREASING INDUSTRIALISATION  HAS RESULTED A BETTER QUALITY OF LIFE IN THE WHOLE WORLD . IT HAS ALSO CAUSED THE GLOBAL DEMAND FOR ENERGY DEVELOP AT A TREMENDOUS  RATE .THE GROWING DEMAND FOR ENERGY WAS LARGELY FULFILLED BY THE FOSSIL FUELS - PETROLEUM AND COAL. OUR TECHNOLOGIES WERE ALSO DEVELOPED FOR USING THESE ENERGY SOURCE . BUT THESE FUEL WERE PRODUCED OUR MILLIONS  OF YEAR AGO AND THERE ARE ONLY SOME LIMITED RESERVES . THE FOSSIL FUELS ARE NON RENEWABLE SOURCE OF ENERGY, SO WE HAVE TO CONSERVE THEM IF WE CONTINUE CONSUMING . THESE SOURCE AT SUCH ALARMING RATES, WE WOULD SOON WITHOUT ENERGY. IN ORDER TO PREVENT THE ALTERNATE SOURCE OF ENERGY WERE EXPLORED . BUT WE CONTINUE TO WE DEPENDENT LARGELY ON FOSSIL FUEL FOR  MOST OF OUR ENERGY NEEDS .

 

BURNING OF FOSSIL FUEL HAS OTHER DISADVANTAGES TOO . THE OXIDES OF CARBON, SULPHUR AND NITROGEN THAT ARE RELEASED ON BURNING FOSSIL FUELS ARE ACIDIC OXIDES. THESE CAUSES ACID RAIN WHICH AFFECT OUR SOIL AND WATER RESOURCES IN ADDITION TO THE AIR POLLUTION ,RECALL THE GREEN HOUSE EFFECT OF GASES SUCH AS CARBON-DIOXIDE  AND METHANE .

2)  THERMAL POWER PLANT -

                                                             LARGE AMOUNT OF FOSSIL FUEL ARE BURNT IN POWER STATIONS EVERY DAY TO HEAT UP WATER TO FORM STEAM WHICH FURTHER RUNS THE TURBINE TO PRODUCE ELECTRICITY. THE TRANSMISSION OF ELECTRICITY IS MORE EFFICIENT THAN TRANSPORTING PETROLEUM OR COAL OUR THE SAME DISTANCE . MANY THERMAL POWER PLANTS ARE SET UP NEAR OIL OR COAL FIELD . THE TERM THERMAL POWER PLANT IS USED SINCE FUEL IS BURNT GENERATE HEAT ENERGY WHICH IS CHANGED INTO ELECTRICAL ENERGY .

 

3) HYDRO POWER PLANT -

                                              HYDRO POWER PLANTS CHANGES THE POTENTIAL ENERGY OF FALLING WATER INTO ELECTRICITY .SINCE THERE ARE FEW WATER FALLS WHICH COULD BE UTILISED AS A SOURCE OF POTENTIAL  ENERGY,HYDRO POWER PLANTS ARE RELATED WITH DAMS .IN THE LAST CENTURY A LARGE NO OF DAMS WERE CONSTRUCTED ALL OVER THE WORLD.IN ORDER TO GENERATE HYDEL ELECTRICITY,HIGH RISE DAMS ARE BUILT ON THE RIVER TO OBSTRUCT THE FLOW OF WATER AND THERE BY COLLECT WATER IN BIG RESERVOIRS . THE WATER LEVEL INCREASES AND THIS PROCESS THE KINETIC ENERGY OF FLOWING WATER GETS CONVERTED INTO POTENTIAL ENERGY .THE WATER FROM THE HIGH LEVEL IN THE DAM IS ALLOWED TO FALL THROUGH PIPES,TO THE TURBINE AT THE BOTTOM OF THE DAM.
