...waste plant switchgrass, which grows throughout the Midwestern prairies, with little input from farmers. Instead of fuel from food, switchgrass cellulosic ethanol promises fuel from virtually nothing - and a new paper in the Proceedings of the National Academy of Sciences (PNAS) argues that it's worth making the switch...
...Oslo quantified the full impact of all our driving, shipping and flying on the climate, and found that transport accounts for around 16% of all man-made carbon emissions - with auto fuel taking the largest chunk. That percentage will only increase over the coming decades - unless we can switch to something cleaner...
