The verdict on biofuels is in, and the catchphrase seems to be over-promised and under-delivered. Biofuels have been in public use in some form or the other for a long time (remember the Ford Model T that ran on hemp-derived fuel?). However, in reality, innovation in biofuels for widespread use is much more recent. First generation biofuels made out of sugar, starch and edible oils still occupy a major share of the total market.
