Availability of power is one of the biggest inputs necessary for the sustained growth of any economy. This becomes even more important for a state like Tamil Nadu, which is one of the most industrialized and urbanized states in India. Over the last few years, Tamil Nadu has been facing massive power deficits. According to the CEA, the state was expected to have a power deficit of around 18 percent in 2012-13. As a result, in recent times the state is facing huge power cuts. On an average of 3-4 hours power cuts are being experienced by consumers in the state. Given this situation this paper attempts to look at the alternative energy for the growing power deficits in Tamil Nadu with the following objectives, 1) to identify the renewable sources in which Tamil Nadu can improve and 2) to examine the growth performance of wind power sector. It is evident from the studies explained that all the indicators of wind energy are noticed significant growth during the period 1990-91- 2013-14 in Kanyakumari district. Among the indicators, the installed capacity posted highest growth rate compare to wind energy generation, number of wind mill commissioned. From the analysis, it is witnessed that the performance of wind power sector has grown considerably in the study period. This paper suggests that Tamil Nadu is one state which has fully converted the challenges into opportunity and ranked first in the country with maximum carbon credit through wind energy generation and in this continued effort to combat environmental degradation and promoting clean energy. So the government should work to design and formulate adequate policies in order to ensure energy security and control environment pollution.
