I have also read the HINDU article by M R Srinivasan.Though he mention about lowest energy cost in Fracnce he doesn't give the actual value of energy in cost per unit. He only mention the cost per unit energy from various atomic plants and never compares it with any other source or the prevailing energy cost in market. One should also understand that pricing of energy sources like electricity and fuel is run by govt. policies than market. Thats why we have subsuidieced gas connection and different electricity charges with different slab and for commercial establishment. It is a well know fact that Hydroelectric power is the cheapest and Srinivasan is trying to prove Nuclear is cheaper since it is cheaper in france..! funny!
