Biomass-Solar Energy: A Comprehensive Review of Sustainable Energy Generation

India is the world's most populous country and plays a crucial role in achieving the United Nations' Sustainable Development Goals by 2030. SDG No. 7 (affordable and clean energy) and climate change reduction goals are essential for sustainable development. This review discusses clean energy potential, obstacles and stimulants, and renewable energy policies in India, focusing on solar and biomass resources. With biomass resources, the nation can generate 130 million tonnes of oil equivalent annually, and it can generate 5,000 trillion kWh of solar energy annually. For the production of renewable energy, biomass resources such as Jatropha, sweet sorghum, cassava, rice, coconut, and agricultural leftovers can be employed. The purpose of this review is to highlight the benefits of using bioenergy to achieve a sustainable energy future through financial incentives, enhanced research, public awareness, social amenities, strategic replenishment, and productive intergovernmental collaborations. Solar thermal and photovoltaic systems offer great possibilities for grid-connected, off-grid, and hybrid installations. Site-specific considerations such as incentives, financing, research, public awareness, government regulations, and private investments influence the techno-economic viability and environmental relevance of solar power and bioenergy for India's sustainable development.
