Abandoned farmlands are key to sustainable bioenergy

Scientists estimate that globally up to 4.7 million square kilometers of abandoned lands could be used for sustainable bioenergy production, with a potential yield of nearly half the land area of the United States. The researchers found that biomass from these lands could provide energy equivalent to about 41 exajoules, which would sat...

Biofuels: More than just ethanol

The study found that certain biofuel crops, such as switchgrass and hybrid poplar, can significantly reduce greenhouse gas emissions by up to 85% compared to gasoline and diesel. These crops also offset the largest amounts of fossil fuels reduced emissions when used for electricity generation via biomass gasification.
