Energy is a vital input for economic and social development of any country. With increasing industrial and agricultural activities in the country, the demand for energy is also rising. Solar, wind and biomass are accepted as dependable and widely available renewable sources of energy. Development of an energy model will help in the proper allocation of these renewables in meeting the future demand of energy in India. The present work deals with the development of an Optimal Renewable Energy Model (OREM) for the effective utilisation of renewable energy sources in India for the year-2020-21. The objective of the Optimal Renewable Energy Model (OREM) was minimising cost/efficiency ratio based on social acceptance, reliability, demand and potential constraints. The OREM model allocated renewable energy sources for different end-uses such as lighting, cooking, pumping, heating, cooling and transportation for the year 2020-21.
