The population and economy development of a nation are the two crucial factors, which influence the consumption pattern of an essential component of a life, energy, throughout the world. The fossil fuel resources are predominantly used for each and every kind of activity and its consumption is rapid and therefore it is necessary to investigate the existing energy usage, consumption pattern and demand, especially in urban areas of developing countries for efficient utilization of energy. In this respect, this paper examines the existing energy usage, consumption pattern and demand in different zones of the social sectors of Madurai and Salem cities, which are respectively the second and fifth largest in terms of population in Tamil Nadu, India. We have concentrated mainly on energy consumers in different zones of social sectors in these two cities. We have evaluated the energy consumption in the social sector through questioner survey and the energy demand is calculated. The variations in energy utilization are assessed by using cluster sampling method and the results are discussed. Since the energy demand and environmental deterioration are in rising trend, it is necessary to execute the energy conservation measures and utilize the renewable energy sources to overcome the energy demand in the Madurai and Salem cities.
