A new report released by NASA’s Goddard Space Flight Center and a team of scientists at the National Socio-Environmental Synthesis Center led by applied mathematician Safa Motesharrei says that the world is coming to an end. While they preach a ...
Supporters of the renewable fuels industry turned out en masse on Thursday, desperate for the U.S. government to change course after last month announcing a plan to lower the amount of biofuel
s that must be added to the fuel supply in ...
SUMMARY The EPA announced that better fuel efficiency has led to proposed cuts in the amount of ethanol
required to be blended into gasoline next year. These changes come amid revelations over the environmental impact of increased U.S. corn
Barack Obama on Friday backed away from the notion of corn ethanol
representing a cure for climate change, as he proposed to cut the amount of ethanol
that is blended into the US gasoline supply.
