For the transportation industry, biofuels can be integrated without the high costs of infrastructure modification. Car engines that run on ethanol, for example, can be easily converted to run on bioethanol or biodiesel, and the fuel can be dispensed just as gasoline is today.

A June 2009 report from Pike Research predicts that combined biodiesel and ethanol sales will rise from $76 billion in 2010 to $247 billion in 2020. It predicts that government commitment to biofuels development as well as the emergence of new biofuels technologies, including waste grease biofuels, Jatropha biofuels, and algae-based biofuels, will drive improvements in the overall economics of the energy source.

Do some searches for up and coming technologies to convert coal to gasoline and algae to biodiesel. The algae can eat up the CO2 and turn it into oxygen, starch, oil and protein.

May be a driver of emerging markets and industrializing countries, where conditions are favorable to growing next-generation biofuel crops, and fossil oil importation is currently prohibitively expensive.

Biofuels may provide a regional solution as part of a nation-wide transformation to renewable fuels. The mid-west, for example, could support locally produced and sold biofuels.
