The following Table shows the total power shortage percentage in India from 1991- 1997. Show the data in the form of a Bar graph taking shortage percentage for the years on the Y-axis and the years on the X-axis.

a) Is the shortage percentage of power increasing or decreasing?

b) If shortage percentage of power increases year by year, how will it affect on human life? Explain.

a) There is no continuous increment or decrement of shortage percentage of power. The shortage percentage of power in India decreased from 1991 to 1992. It was increased from 1992 to 1993. Again decreased from 1993 to 1995. Then the shortage percentage increased from 1995 to 1997.

b) If shortage percentage of power increases year by year, then

(i) This results in fuel crisis

(ii) This results in economical crisis. (As the fuel cost increased with raising demands.)

(iii) The increase of shortage percentage of power indicates over consumption of power or energy sources. This leads to pollution.
