An intricate and interwoven web of issues in the areas of energy security, sustainable transition, and climate action face India as one of the largest and fastest-growing countries in the world. This study explores the complex environment of India's energy industry, looking at its current energy sources, vulnerabilities to supply disruptions, and existing energy security measures. It examines the nation's continuous transition toward renewable energy sources, in particular, as well as the ramifications of this transformation for the economy and the environment. However, there are several obstacles on the path to sustainability, particularly with regard to addressing climate change. India faces particular challenges in its efforts to meet the energy needs of its expanding population while also committing to reduce greenhouse gas emissions. This essay examines these issues and suggests solutions for reducing climate change's effects while preserving energy security.  This research study tries to clarify the crucial connection between energy security, sustainable transition, and climate action in India through case studies and policy recommendations. It underlines the need for a comprehensive strategy that addresses these problems simultaneously and identifies the steps that India should take to move toward an energy future that is more secure, sustainable, and climate resilient.
