Currently it is not as economical as using fossil based fuels.
For instance, the production of ethanol as a fuel is currently more expensive than the extraction of octane from crude oil.
And also, fossil fuels tend to have a higher heat of combustion (more power).

What are the advantages of alternative fuels used in automobiles?
The primary advantage to alternative fuels such as biodiesel in automobiles is to lower harmful emissions into the atmosphere in the hopes of off-setting further damage to the ozone. Currently the biodiesel of choice, at least in the United States, is ethanol derived from corn. There are two affective faults with the current system and crop of choice, first is the amount of ethanol derived from corn is minimal compared to alternative crops such as water based algae. This has a subproblem rooted in that the amount of space necessary to grow the corn to produce sufficient amounts of ethanol is staggering. Secondly, the amount of machinery and vehicles using gasoline or standard diesel in the process of allocating the ethanol from the corn far offsets the benefits of using the ethanol to begin with. Side note - the performance of vehicles on biodiesel is similar to that of standard diesel.
