 Research efforts to provide cleaner energy through sustainable processes and utilization of renewable resources are increasingly important due to the continual desire to reduce human activities' environmental footprints, mitigate climate change effects on present and future existence, and shift to more environmentally friendly alternatives. Bioenergy accounts for over one-third of all energy used in Sweden, with biomass providing about 60% of fuel for district heating and a significant role in the transport sector. The Swedish bioenergy sector's state-of-the-art is presented based on literature and current statistics, discussing overall production and utilization in different sectors, potential challenges, and environmental considerations.
