Does biodiesel make large SUVs O.K.?

Is there enough biodiesel to go around?

So you drive a large SUV, yet you have SUV guilt? What can you do? Convert it to a biodiesel.

"LoveCraft Bio-Fuels in Los Angeles has converted more than 1,400 vehicles to run on vegetable oil by installing a system of heaters, pumps and filters. Its most famous client was Gov. Arnold Schwarzenegger, who modified one of his Hummers," writes MSNBC.

“To take the vehicle that symbolizes one of the worst environmental violators and get it to run on vegetable oil was pretty cool,” LoveCraft co-founder Brian Friedman said.

That is cool, especially for old SUVs until they are retired. Still, is there enough biodiesel to replace oil? Not according to most experts - not even close. Even worse, such a move could drastically increase the price of many foods.

Still, its hard to argue against waste-driven biodiesel, but it must be accepted that this is just a niche. This is a great program for older vehicles, but it certainly isn't an excuse to buy new, large SUVs.
