THE SOURCES OF ENERGY CAN BE DIVIDED INTO TWO PARTS ONE IS RENEWABLE SOURCES AND THE OTHER IS NON RENEWABLE SOURCES.
RENEWABLE SOURCES OF ENERGY:-
IT IS THE SOURCE OF ENERGY WHICH IS NON PERISHABLE.IT CAN LAST FOR ENDLESS PERIOD OF TIME.
FOR EXAMPLE: - SUN, WIND, TIDE ETC.
THESE SOURCES OF ENERGY CAN BE EXPLOITED FOR A LONG PERIOD OF TIME.
USES:-
- THE SOLAR ENERGY GENERATED FROM SUN IS BEING USED FOR THE PRODUCTION OF ELECTRICITY, FOR COOKING FOODS IN SOLAR COOKERS ETC.
- WIND ENERGY USED FOR THE GENERATION OF ELECTRICITY AS WELL AS PUMPING WATER FROM WELLS, TUBE WELLS.IT IS ALSO BEING USED FOR IRRIGATION PURPOSES.
- THE TIDAL ENERGY IS BEING USED FOR GENERATION OF ELECTRICITY.
ADVANTAGES:-
- THE SOURCE OF ENERGY ARE NON PERISHABLE AND PERISHABLE AND PRESENT IN AN ADEQUATE AMOUNT.
- GENERALLY THE RENEWABLE SOURCES OF ENERGY ARE POLLUTION FREE.
DISADVANTAGES:-
- FOR USING THIS SOURCE OF ENERGY A LARGE CAPITAL INVESTMENT IS REQUIRED.
- IT ALSO REQUIRES VARIOUS CONDITIONS TO BE FULFILLED FOR ITS LARGE SCALE EXPLOITATION. FOR EXAMPLE FOR EXPLOITING RIVERS AS THE SOURCE OF ENERGY SETTING OF HYDRO ELECTRIC POWER PLANTS ARE TO BE BUILT WHICH REQUIRES THAT THE RIVERS SHOULD BE PASSING THROUGH MOUNTAINS AND RIFFS BY WHICH THE DAMS CAN BE MADE EASILY FOR STORING WATER .
- GENERALLY FOR EXPLOITING THESE RESOURCES IN A LARGE SCALE A HUGE CAPITAL INVESTMENT IS REQUIRED.
NON –RENEWABLE SOURCE OF ENERGY:-
IT IS THE SOURCE OF ENERGY WHICH ARE PERISHABLE IN NATURE. IT IS MAINLY THE FOSSIL FUEL PRESENT INSIDE THE EARTH CRUST.
FOSSIL FUELS ARE FOUND IN DIFFERENT PHYSICAL STATES (SOLID, LIQUID, AND GAS).
IN SOLID STATE IT IS FOUND IN THE FORM OF COAL.
IN THE LIQUID STATE IT IS FOUND IN THE FORM OF CRUDE OIL.
IN THE GASEOUS STATE IT IS FOUND IN THE FORM OF C.N.G (COMPRESSED NATURAL GAS).
USES:-
- FOSSIL FUEL IS BEING USED BY HUMAN BEINGS FOR DIFFERENT PURPOSES IN VARIOUS WAYS.
- PETROL AND DIESEL ETC. WHICH ARE OBTAINED BY THE REFINING OF THE CRUDE OIL ARE BEING USED AS THE FUEL FOR THE LOCOMOTIVES LIKE BUS, TRUCK, CARS, BIKE, PLANE, SHIP ETC.
- C.N.G, LPG ARE USED IN HOUSES AS FUEL FOR COOKING PURPOSES.
- COAL IS BEING USED AS FUEL FOR COOKING AS WELL AS GENERATION OF ELECTRICITY IN THERMAL POWER PLANTS.
- KEROSENE IS BEING USED AS A FUEL OF STOVES IN COOKING PURPOSES.
- DIESEL AND KEROSENE IS ALSO BEING USED FOR GENERATION OF ELECTRICITY BY THE HELP OF SMALL GENERATORS.
- C.N.G IS ALSO USED AS FUEL FOR THE VEHICLES.
ADVANTAGES:-
- THE CAPITAL INVESTMENT IS LOW AND REQUIRED CONDITIONS FOR USING THIS SOURCES ARE LESS AND CAN BE CHEAPLY ACHIEVED AS COMPARISON TO THE RENEWABLE SOURCES OF ENERGY.
DISADVANTAGES:-
- THE SOURCE IS LIMITED.
- IT TAKES MILLIONS OF YEARS TO GET RENEWED.
- AS MAINLY THE NON RENEWABLE SOURCES CONSIST OF HYDROCARBONS IT GIVES OUT CARBON DIOXIDE AND CARBON MONOXIDE AS ITS RESIDUE AFTER ITS USE. THESE ARE THE HARMFUL POLLUTANTS WHICH CAUSES POLLUTION. THESE ARE THE GASES RESPONSIBLE FOR THE GREEN HOUSE EFFECT.
