Alternative sources of energy are playing a bigger role in the world's electrical systems as the world shifts to sustainable ones. Energy security, greater energy availability, and positive environment impact are just a few benefits of using RE sources. All across the world, they are easily accessible. The globe is currently undergoing an energy transition as countries move from conventional to non-conventional energy sources. A few of the concerns guiding this shift are air pollution, energy security, climate change, and technological advancements. Governments have responded to this shift by putting in place several approaches to promote renewable energy. The utilisation of RE resources in the power sector and efforts to implement core policies are two areas that are highlighted in this paper's evaluation of the general policies in 42 countries. We also examine the applicability of the most common RE policies in use globally to India. Based on our findings, it is recommended that India adopts a comprehensive strategy encompassing FIT (Feed-in-Tariff), RO (Renewable Obligation), RPS (Renewable Portfolio Standard), Quota system, and concurrent upgrades to the grid infrastructure. This approach aims to facilitate the generation of renewable electricity and supports India in achieving its 2030 sustainability targets.
