<b>The Required Policy Change in Energy Sector for India’s Energy Security</b> The existing clean energy technologies are wind and solar which are intermittent in nature and depends on the availability of the wind and sunlight. To give stability to the power supply another source of clean energy which does not depend on uncontrollable wind or sunlight is required. Currently nuclear energy is the only other clean energy technology which has been developed to such an extent to support the transition. This paper proposes that captive and private nuclear power generation shall be allowed using Small Modular Reactors SMRs . Private Investments in the sector lead to more innovations in the field.
