**4. Conclusion**

Energy from biomass is a need of time to face the future energy challenges that would arise by the rapid depletion of fossil fuels. Biomass extraction for energy purpose is acceptable only if it is justified economically and socially, at the same time its strategy must aim at sustainability. A drive without sustainability would create a system to be abandoned in near future. In pursuit of sustainability all the moves should be towards achieving and using technologies on the basis of economic feasibility and viability. The selection of energy production technology would be so as to sustain the ecological conditions and not to instigate the food versus fuel conflict concerning the land and water use. Also, there should have a positive environmental balance for the whole life cycle of the biomass used for energy extraction. The best alternative to the combustion-based plant a biomass integrated gasification combined cycle (BIGCC) plant can be suitable pelleted or briquetted biomass with low-cost technology and developed locally.
