The demand for energy grows every day in the world, but with grave threat of environmental decay and limited conventional resources. There is a radical shift in demand for clean and sustainable energy resources and consumption. International Solar Alliance is thus a potent mechanism with key idea to “harmonize and aggregate demand for solar finance, solar technologies, innovation, R&D, and capacity building”. It aims to mobilize USD 1 trillion for deployment of solar power capacity of 1000 GW by 2030 and bring together 121 countries that lie between the Tropics of Cancer and Capricorn that receive abundance of sunlight. Thus, the study will outline the strategy and approach India is taking to enhance its solar power potential, how India will achieve SDG 7: Affordable and Clean Energy and bring out India’s potential to position itself in key global leadership role in area of climate change, renewable energy and sustainable development.
