Abstract

AbstractFossil fuel-based energy economies are shifting towards a renewable energy-based economy. Renewable energy comes from naturally replenishing sources with low carbon emissions. Solar, wind, bio and geothermal are well-accepted renewable energy sources. Among renewable energy, bioenergy is the prominent energy source that is utilized in the form of biofuels for transportation, bioenergy for heat and power applications. Most of the bioenergy is obtained from biomass and crop residues, and wastes materials, energy crops as the main feedstock. There are several bioenergy conversion technologies employed at the commercial level which are combustion, gasification, pyrolysis, torrefaction, hydrothermal processes, anaerobic digestion, fermentation and transesterification. The roles of bioenergy conversion technologies are to provide reliable and sustainable energy that have needed a policy framework. Bioenergy policies define the target based for technology-specific policies to regulate energy production, distribution and utilization. This article is focused on bioenergy technologies and bioenergy policies.KeywordsBioenergyBioenergy policiesBioenergy conversion technologies
