20. Challenges and strategies A country of the size of India cannot afford to plan its economy on the basis of large scale import of energy resources or energy technologyA country of the size of India cannot afford to plan its economy on the basis of large scale import of energy resources or energy technology Indigenous development of energy technologies basedIndigenous development of energy technologies based on domestic fuel resources should be a priority for us. Nuclear power must contribute about a quarter of the total electric power required 50 years from now, in order to limit energy import dependence in percentage terms at about the current level.Nuclear power must contribute about a quarter of the total electric power required 50 years from now, in order to limit energy import dependence in percentage terms at about the current level.
