INTRoDUCTION Name: Kaushik sanghani Mo:919909401178, India Welcome to My Project on Source of Energy windMill

A PROJECT ON SOURCES OF ENERGY : 

A PROJECT ON SOURCES OF ENERGY

INTRODUCTION:NO ACTIVITY IS POSSIBLE WITHOUT ENERGY.ENERGY IS AVAILABLE TO US IN FORMS OF FUELS AND ELECTRICITY.ENERGY SOURCES ARE RENEWABLE OR NON RENEWABLE.RENEWABLE SOURCES OF ENERGY ARE SUN,WATER WIND, EARTH,WOOD,BIOMASS ETC.NON RENEWABLE SOURCES OF ENERGY ARE COAL,PETROL,PAPER,CNG,LPG,WOOD ETC.FUELS CAN BE SOLID ,LIQUID OR GASES AMONG THIS ONE OF THE MOST IMPORTANT SOURCE ARE WIND MILL. : 

INTRODUCTION:NO ACTIVITY IS POSSIBLE WITHOUT ENERGY.ENERGY IS AVAILABLE TO US IN FORMS OF FUELS AND ELECTRICITY.ENERGY SOURCES ARE RENEWABLE OR NON RENEWABLE.RENEWABLE SOURCES OF ENERGY ARE SUN,WATER WIND, EARTH,WOOD,BIOMASS ETC.NON RENEWABLE SOURCES OF ENERGY ARE COAL,PETROL,PAPER,CNG,LPG,WOOD ETC.FUELS CAN BE SOLID ,LIQUID OR GASES AMONG THIS ONE OF THE MOST IMPORTANT SOURCE ARE WIND MILL.

WIND MILL : 

WIND MILL A WIND MILL IS A MACHINE WHICH WORKS WITH THE ENERGY OF BLOWING AIR OR WIND. IT CONSISTS OF LARGE BLADES TO CATCH THE WIND WHEN THE WIND STRIKES AGAINST THESE BLADES,THEY START ROTATING. THIS MOTION THEN CAN BE PASSED ON TO OTHER CONNECTED PARTS AND IS USED TO DO USEFUL WORKS.

Slide 5: 

WIND MILLS CAN BE USED TO DRAW WATER FROM TUBE WELLS AND TO RUN FLOUR MILLS. IN THE ARRANGEMENT OF WIND MILL ,CENTRE OF THE WIND MILL BLADES IS CONNECTED TO ONE END OF A DEVICE CALLED THE CRANK. IT IS A LONG ROD HAVING A U-SHAPED BEND WHICH CONVERT THE ROTATRY MOTION INTO UP DOWN MOTION OR VICE VERSA.

Slide 6: 

THE U-SHAPED BEND OF THE CRANK IS CONNECTED TO THE ROD OF THE WATER PUMP. WHEN THE BLADES ROTATE BECAUSE OF BLOWIN WIND THE CRANK ALSO ROTATES. THE CRANK,THEN LIFTS THE PUMP ROD UP AND DOWN AND THE WATER IS DRAWN FROM THA GROUND.

GENERATION OF ELECTRICITY : 

GENERATION OF ELECTRICITY THESE DAYS WIND ENERGY IS ALSO USED TO GENERATE ELECTRICITY. THIS CAN BE DONE BY THE HELP OF WIND MILLS ONLY. WHEN THE BLADES OF WIND MILL ROTATE THEY TURN THE COIL OF AN ELECTRIC GENERATOR TO PRODUCE ELECTRICITY.

LIMITATION OF WIND ENERGY : 

LIMITATION OF WIND ENERGY ALTHOUGH WIND ENERGY CAN BE USED FOR DIFFERENT PURPOSES. IT HAS AN IMPORTANT LIMITATION BECAUSE IT IS NOT AVAILABLE ALL YHE TIMES AND AT ALL THE PLACES FOR DOING VARIOUS TYPES OF WORK. THERE IS NO GUARANTEE THAT WE WILL GET WIND ENERGY WHEN WE REQUIRE. IT BECAUSE THERE IS NO PLACE IN THE WORLD WHERE THE WIND BLOWS ALL THE TIME.

ADVANTAGES OF WIND ENERGY : 

ADVANTAGES OF WIND ENERGY WIND ENERGY DOES NOT CAUSE ANY POLLUTION. IT IS AVAILABLE FREE OF COST. THE SOURCES OF WIND ENERGY SUCH THAT, AIR IS AN INEXHAUSTIBLE AND REVERSIBLE SOURCES.

LIKE WIND ,SUN IS ALSO ONE OF THE MOST SOURCE OF ENERGY .LET US DISCUSS ABOUT SOLAR ENERGY : 

LIKE WIND ,SUN IS ALSO ONE OF THE MOST SOURCE OF ENERGY .LET US DISCUSS ABOUT SOLAR ENERGY

SOLAR ENERGY : 

SOLAR ENERGY SUN IS THE MOST DIRECT AND MAJOR SOURCE OF ALL TYPES OF ENERGY WHICH WE USE. ENERGY OBTAINED FROM THE SUN KNOWN AS SOLAR ENERGY. A LARGE AMOUNT OF SOLAR ENERGY IS FALLING ON THE EARTH BUT IT IS VERY MUCH DIFFUSED AND SCATTERED. THEREFORE IT CAN BE USED AS SUCH TO RISE THE TEMPERATURE OF DIFFERENT BODIES BEYOND A CERTAIN LIMIT.

HARNESSING OR SOLAR ENERGY : 

HARNESSING OR SOLAR ENERGY 1 DIRECT USE OF SOLAR ENERGY: THE SOLAR ENERGY CAN BE USED DIRECTLY EITHER BY COLLECTING IT AS HEAT OR BY CONVERTING IT DIRECTLY INTO ELECTRICITY. 2 INDIRECT USE OF SOLAR ENERGY: THE SOLAR ENERGY CAN BE USED INDIRECTLY BY CONVERTING IT INTO CHEMICAL ENERGY LIKE BIOMASS OF PLANTS. OTHER INDIRECT WAYS OF HARNESSING OF SOLAR ENERGY ARE;

Slide 13: 

HARNESSING THE ENERGY OF THE WIND. UTILISING THE ENERGY OF THE SEA WAVES. UTILISING THE ENERGY DUE TO TEMPERATURE DIFFERENCE IN THE WATER AT DIFFERENT LEVELS IN OCEANS.

ADVANTAGE OF SOLAR ENERGY : 

ADVANTAGE OF SOLAR ENERGY IT IS RENEWABLE SOURCES OF ENERGY AND THEREFORE,IT IS INEXHAUSTIBLE SOURCE OF ENERGY. SOLAR ENERGY DOES NOT CAUSE ANY POLLUTION. THE ENERGY AVAILABLE FROM SUN IS IN PLENTY ESPECIALLY IN HOT COUNTRIES LIKE OURS.IT IS FREE OF COST.

DISADVANTAGES OF SOLAR ENERGY : 

DISADVANTAGES OF SOLAR ENERGY SOLAR ENERGY IS NOT AVAILABLE AT NIGHT. THE SOLAR ENERGY IS VERY MUCH DIFFUSED AND SCATTERED. SOLAR ENERGY IS NOT AVAILABLE IN SUFFICINT AMOUNTS OF ALL THE TIME. THE INTENSITY OF SOLAR ENERGY DECREASE DURING WINTER SEASON AND RAINY SEASON.

THANKYOU TO ALL :
