Abstract: Energy is a vital input for social and economic development of any nation. Renewable energy technologies can help countries meet their policy goals for secure, reliable and affordable energy to expand electricity access and promote development. Renewable energy sources, especially solar and wind energy, are likely to play a significant role in providing reliable and sustainable electricity to consumers. Renewable Energy (RE) sources form a minuscule portion of India’s overall Energy consumption today, with increasing agricultural and industrial activities in the country; the demand for energy is also increasing. Formulation of an energy model will help in the proper allocation of widely available renewable energy sources in meeting the future energy demand in India Many developing countries are increasingly making commitments to promote low carbon economy by adopting sustainable energy technologies. In this regard, different policies could be applied to reducing carbon emissions, such as enhancing renewable energy deployment and encouraging technological innovations. Diffusion of Renewable Energy Technologies (RETs) is governed by the status of the technology in terms of efficiency and techno-economical feasibility. The states plans for the deployment of resources for development, with special reference to sustainable environment and the demand and supply energy model help to provide more focus on the long term goals. This paper presents an approach to apply diffusion modeling technique to review policies supporting Renewable energy technology deployment and use diffusion parameters to provide inputs for designing future programmes. The wind and solar power are selected for detailed analysis. The results show how present trends and future forecasts of electricity-generating technologies change the electricity generation in the country.
