Peaceful Uses of Atomic Energy
“Peace hath her victories no less renowned than war: ” —Milton
Introduction: The human world has been changing since the very beginning. The greatest change has been brought about by the discovery of the atom. It has revolutionized the whole thinking of man. A very great source of energy has been discovered. It is full of hope as well as danger. When we think of the atom we think of destruction. But it is so only in the case of war. Atomic energy can be used for the service of mankind.
Brighter side: Atomic energy can change earth into heaven. Its advantages are many. It can be used for creative and peaceful purposes. The results will be good in every field. The earth itself will be better and free. Men living in hardships will be healthier and happier.
Better world: Atomic energy can change the face of the earth. Deserts of dust and poles covered with ice be turned into smiling lands bright with colorful vegetation. The climate can be made more wholesome and comfortable. There can be artificial rain. The whole scenery would be beautiful.
Healthier men: Atomic energy can cure painful diseases that were considered incurable. It can make food better and more wholesome. Atomic energy can preserve food for a longer time and food can be produced in laboratories without any dependence on crops and soils. The curse of poverty can be eliminated. This will make mankind healthier, happier and more beautiful. Life will be longer.
Freedom from hard work: Atomic energy can do all the hard and boring work for the man. And it can do it much more quickly and efficiently. National and international transport can become quicker and cheaper. There would be no long and tedious journeys. Mills and factories will do more work. Even everyday common work will be done by machines. Man will be freed from all hard physical labor.
Conclusion: Atomic energy, on the whole, has much greater advantages than fear. But there is one condition ‘ Man should use it wisely as a man and not foolishly like a demon. It is certain that if men do not destroy themselves with it, atomic energy will, make human life the happiest and comfortable.
Non-Conventional Sources of Energy
Energy generated by using wind, tides, solar, geothermal heat and biomass including farm and animal waste as well as human excreta is known as non- conventional energy. These sources are renewable or inexhaustible and do not cause environmental pollution.
Wind Energy: Wind power is harnessed by setting up a windmill that is used for pumping water, grinding grain and generating electricity. The gross wind power potential of India is estimated to be about 20,000 MW. Areas with constantly high speed preferably above 20 km per hour are well-suited for harnessing wind energy.
Tidal Energy: Seawater keeps on rising and falling alternatively twice a day under the influence of gravitational pull of moon and sun. This phenomenon is known as tides. It is estimated that India possesses 8000-9000 MW of tidal energy potential. The Gulf of Kuchchh is best suited for tidal energy.
Solar Energy: Sun is the source of all energy on the earth. It is the most abundant, inexhaustible and universal source of energy. All other sources of energy draw their strength from the sun. India is blessed with plenty of solar energy because most parts of the country receive bright sunshine throughout the year except for a brief monsoon period. India has developed technology to use solar energy for cooking, water heating, water dissimilation, space heating, crop drying, etc.
Geo-Thermal Energy: Geothermal energy is the heat of the earth’s interior. This energy is manifested in the hot springs. India is not very rich in this source.
Energy from Biomass: Biomass refers to all plant material and animal excreta when considered as an energy source Some important kinds of biomass are inferior wood, urban waste, bagasse, farm animal and human waste.
Importance of non-conventional sources of energy: The non-conventional sources of energy are abundant in nature. According to energy experts, the non-conventional energy potential of India is estimated at about 95,000 MW. These are renewable resources. The non- conventional sources of energy can be renewed with minimum effort and money. Non-conventional sources of energy are pollution-free and eco-friendly.
