Vegetable oils as alternative energy bio-diesel is that it can tolerate low rainfall (as little as 250 ml per year), far below what most food-crops require, thus reducing yet more their potential to compete.

Potentially algae could produce much more oil per area of land than current farming methods. So producing vegetable oil this way should result in less deforestation and less competition for food production land. One expert wrote: "As demonstrated here, microalgal biodiesel is technically feasible. It
