The dedication to promote sustainable energy requires supportive policy and legislative framework. The Indian government is taking certain initiatives relating to energy sector particularly in order to develop renewable energy resources. This approach towards the development of verticals of sustainable energy is very encouraging. The steady and systematic development of non- conventional energy resources will give fruitful results for securing the better future. One of the main reasons for exploring the non- conventional energy resources or sustainable energy resources, because these resources are environmentally as well as economically sustainable by comparison with the conventional energy resources. The research paper will trace the development of sustainable energy in India, explores the provisions of renewable energy sources and concentrates on developing the idea of sustainable energy in comparison to other existed resources. In conclusion, it highlights what kind of paradigm shift would be required to be strengthened legal as well as policy making for securing better future in the field of sustainable energy.enSustainable EnergyConventional and Non-Conventional Energy ResourcesLegal FrameworkArticle
