Energy Crisis, the problem that we can face in the near future. What can we do?

Energy is the most important part of our life which is obtained from various sources. For sustaining our lives, the major source of energy are the sun, water, coal, natural gases, L.P. gases, petroleum products, wood etc. Out of these energies, some are renewable and some are non-renewable. At present world, more and more energy has been used up due to over population. One one hand, there has been an over exploitation of the non-renewable sources of energy: and , on the other hand, there has not been enough search for renewable sources of energy. For example, the petroleum products, coal etc. are being finished in their mines; the forests are being reduced; and the ground water level has decreased. The rate of consumption of the fuel energy is so rapid that they can not last for long time. If the present rate of consumption of fuel energy is continued and no alternative sources of energy are brought in, the fuels like coal, petroleum etc. will be evacuated as. As result, the world is likely to face a serious problem of energy scarcity. such scarcity of energy is known as energy crisis.
It is necessary to conserve energy. There should be economical use of energy. We must also start looking for alternative sources of energy. The main cause of energy crisis is over population. The most effective step to prevent energy crisis can be the control of world's population. The use of non-renewable sources of energy should be avoided and they should be replaced by use of renewable source of energy. Situation should be created for the renewable sources to be reproduced. Household appliances such as tube lights , bulbs, fans, heaters, air conditioners etc. should be switched only when they are in use and devices based on solar energy should be encouraged. More efficient devices which use less amount of energy should be used. All leaking gas pipes, fuel pipes, water pipes etc. should be repaired on time. Deforestation should be stopped and forestation should be implemented. Awareness about the importance of energy conservation should be created in people.
