Great Shortfall in the Supply of Energy Resources

The growth of human being has travelled a long journey. It was the greatest achievement of primitive man when he discovered fire with the help of a stone. With this human history moved very fast.
Later on a number discoveries and inventions were made which changed human life completely. Energy is such a great invention which made our life more and more comfortable. It has become most needed necessity for us. It has created a crisis also.
In the industrially advanced world of today, the demand for energy is increasing day by day. Energy is considered to be life line of any economy and most vital instrument of socioeconomic development of a country.

An energy crisis is any great shortfall in the supply of energy resources to an economy. It usually refers to the shortage of oil and additionally to electricity or other natural resources. The crisis often has effects on the rest of the economy, In particular, the production costs of electricity rise, which raises manufacturing costs. There has been an enormous increase in the demand of energy as a result of industrial development and population growth, in comparison to enhancement in energy production.  
Wood, later on coal was the first source of energy and then came oil and passing through the stage of atomic energy, man is now looking forward to solar energy.
We are naturally anxious to think about our future because we know the bitter truth that a day will ultimately come when we have no more coal or oil. It will mean energy crisis, for which we ourselves are responsible. People who have made careful calculation feel that at present level of exploitation, the coal deposit will last till 2080 and it is also true that poor quality coal with the carbon content of 40 percent only, is not conducive for electricity generation....
