Energy is a critical input for economic rise, social and human development and their welfare. As global warming and oil crisis are becoming a major concern, intensive work have been conducted to secure sources of energy and preserve the environment of the earth. Renewable energy has energed as a promising option to resolve the environment problems and energy issues towards global sustainability. Global energy scenario in recent year have been drastically changed and its also changing with adoption of the new renewable energy conversion technologies. The efficient energy conversion technologies have now emerging as the tool for the development. Many renewable energy resources have available in nature abundantly of which solar, wind and biomass are the important resources in India. The conversion of these sources into useful energy is the crucial task which require state-of-art system configuration. Development os a successful renewable energy sector in both development nations will make a useful long-term contribution to diversity, security and self-sufficiency of energy supply. Renewablw energy will play a leading role in mitigating the environmenyal effects of fossil fuel energy use as it can offer major reductions in harmful emissions particulary greenhouse gases and sulphurous oxides. Continuous growth in the renewable energy industry will create employment opportubities particularly among small to medium enterprises and promote social cohesion and economic stability, particulary in remote and rural regions. It will also provide a plateform for long - term co-operation between industrialized nations and developing countries whose energy demands are expected to grow dramatically in the coming years. The national workshop of theme "Renewable Energy for Sustainable Development of Agriculture and Industries: will emphases on the issues of resources assessment, state-of-art conversion technology and the economy for fitting the appropriate tools in rural areas and in industries for the employment generation and the energy security. I am confident enough that this documentation in the form of proceeding would be immensely useful to the scientist, students, extension personnel, development agencies in understanding the renewable energy potential and adoption of efficient energy conversion technologies. I appreciate the efforts of Dr. M.B. Nagdeve, Dean Faculty of Agricultural Engineering, Dr. S.R. Kalbande, Organizing Chairman and his colleagues in bringing out such excellent documentation.
