We keep strategic reserve for Food Grains, Petroleum Products, and whatnots. These reserves cost a huge amount to the exchequer. This is for preparing ourselves against eventualities, even though these may never arise in a considerable future time.
Similarly we have to foresee the scenario when we may have a crises on the energy front, especially when we look at the pace at which our economy is growing. The supply of energy should have to be faster in order to maintain the economic growth.
The scenario of Energy Front MIGHT change for the better. The options with us are so many. But all these are not immediately available to us. With no solution at hand, we have to immediately plan for the next decades, when we would have a depleted coal reserve and no major new Dams around. Probably, we have no option but to go for an expansion of our nuclear energy capability, up to the day those non-convention energy sources will no longer called so.
