Abstract: Sustainable development of any country aims to make a development that cannot only meet the demands of the present but can also set up the future generation's needs and requirements. Emerging global warming, unfavorable climatic conditions, dependence on fossil fuels, and many other factors pose significant challenges to sustainability in India. To get rid of all these issues, solar energy can play a versatile role in the sustainable development of the country. India is fortunate to have an abundance of solar energy. It is the cleanest energy source on the planet, produces zero carbon emissions, and is the best replacement for energy from fossil fuels. This paper discusses the impact of solar energy in developing a sustainable India. Ways of harnessing solar energy, like solar panels, solar streetlights, solar water heaters, solar signals, and so on, are discussed.

Keywords: Sustainable development, smart cities, solar energy products, smart city strategies & solutions, and Government initiatives.
