Most American consumers have been hit hard by soaring gas prices, and many people from individuals to research firms are searching for an alternative fuel source that is renewable, economical, and environmentally friendly.
Biodiesel made from crops such as corn and soybeans is one such alternative that most people are aware of, but another option, algae biodiesel, is one of the newest and most promising fuel sources to date. One thing is for sure, if a solution to the ever increasing gas prices is not found soon millions of people will be unable to afford their daily commute.
Many people have put their hopes in biodiesel made from crops as the solution to oil dependency. However, there are problems with biodiesel made from crops namely the displacement of food and the amount of crops it takes to produce a gallon of oil. Using food crops such as soybeans and corn to produce oil takes away from the amount crops that could have been used for food.
Using food crops to make biodiesel is also not very economical, it takes an acre of soybeans to produce about 50 gallons of biodiesel and an acre of corn to produce only about 20 gallons of biodiesel. Compared to the 5,000 or more gallons of biodieseal produced from one acre of algae, food crops are underperforming.
