The point is medha should keep her arguements to hydropower and Narmada Bachao Andolan. If the government couldnt extract enough power from a dam elevation of atleast 100 ft then that is a technical issue or somebody just didnt do their jobs right. Turbines will simply turn when a large quantity of water flows from that much height, they dont have minds to refuse to turn. Again the rehabilitation issue is the same its between the government and the people. If somebody is going to oppose hydrpower as a policy then we can rather be begging on the streets. But it is not upto Medha to say we should focus on renewable sources of energy because that is contradictory to her stand as hydro is the best renewable/ cleanest form of energy.
