20% fuel from German fields – and nothing happens…

I quote – for copyright reasons – in my own words… A study by the Federal Government is said to have shown that in Germany 20% of today’s fuel demand can be replaced by biomass cultivation. Original text is in the ADAC 01/07 page 14. In the text “fuel like diesel” I was told by a German government… Have they only looked at rapeseed cultivation? Further thought… By reducing consumption by 50%, 40% organic replacement would be possible. By additional replacement of rapeseed with cereals > 120%… Where do we live? Who turns the Multis off the rooster?
