Every observable movement involves energy. Hence, energy is obviously an important determinant in the development of a nation. To be specific, the standard of living is directly related to the per capita energy consumption in the region. The per capita energy consumption is mostly due to consumption of electricity. Therefore, electric power is one of the key factors in development of a country. The combined effect of population growth and increase in industrial, domestic and agricultural activities are inevitable and the basic reason for the increase in the worldwide energy demand. Particularly in the Indian context, the power demand is likely to increase by 7% per annum in the next few decades; assuming a GDP growth of 9%. The major resources of electricity generation are the conventional fossil fuels: coal, oil and natural gas. At present, 55% of electricity generated in India is from coal. However, use of coal for electricity generation results in increase of CO2 concentration in atmosphere. In this study, an attempt has been made to estimate the increase in CO2 emission on the basis of statistical analysis using the available data of power production and projected population growth.
