Be careful in lumping all biofuels together. While corn-based ethanol is a government scam, other measures may not be. Biodiesel can be made from waste vegetable oil, which while not a solution for the masses, is a viable niche market. For larger scale, algae-based biodiesel uses sunlight as the only input and does not impact the food supply.
Mike Adams has some kind (preliminary) words for this source as well. From your link:
The only truly promising biofuels technology available today is based on microalgae. Feed CO2 to a vat of algae, and you can produce biofuels cheaply and responsibly, without destroying the environment. But these programs are only in experimental phases. Nobody is producing biofuels on a large scale from algae farms (not yet, anyway).
