Can Bioenergy Once again Become a Major Global Energy Source?

For all of human history except the past two centuries or so, bioenergy provided nearly world’s primary energy. Then, fossil fuels largely replaced bioenergy, but concern about climate change and fuel depletion will force a move back to renewable energy, including bioenergy. The main method used here study future global was literature surview relevant published papers, with emphasis both on those after 2020, having focus. key finding is that unlikely greatly increase its share energy consumption, for several reasons. Liquid biofuel production transport likely almost disappear as countries progressively phase out internal combustion engine vehicles. Traditional firewood use also projected fall. There are doubts technical potential not only because it must compete other uses biomass—food, fodder, fibre timber—but in many cases mitigation impact less than approaches, alternative sources. overall conclusion have minor still useful role system, reductions be more important stability
