Modern age is the age of science. Man is moving very fast on the path of development. With that much time, he has collected all the means of happiness for himself. Factories, motor-cars, trains, airplanes etc. are all the result of this tendency. With this expansion, the danger of exhausting resources is increasing day by day.
Resources are limited in nature. In other words, the energy available in nature is also limited. With the increasing population of the world, the requirements are also increasing. Day by day the number of motor vehicles on the roads is increasing incomparably. Be it trains or aeroplanes, the number of all is increasing. Dependence of humans on machines is increasing gradually. All these machines require energy for their operation.
We hope that scientists will be able to discover and develop new sources of energy in time. Apart from this, it is necessary that all citizens understand the importance of energy and become aware of energy conservation. Make a constant effort not to let energy go waste in whatever form it may be.
