The Best Crops for Biofuel Production. Different crops are used for biofuel, including wheat, sunflower, soybean, and sugarcane. Biofuel production relies on energy crops grown in Europe, the U.S. and other places around the world. Alternative fuels are used to power vehicles and reduce greenhouse gas emissions.
For years, politicians, journalists and scientists have touted biofuels -- fuels made from plants -- as a way to decrease the world's consumption of fossil fuels, especially oil. These so-called energy crops include wheat, corn, soybeans and sugarcane [source: Walker ].mong other things, some energy crops compete with food crops for land, creating problems like higher food prices and deforestation. In addition, the costs of converting some energy crops, as well as retrofitting cars and power plants to run on biofuel, can be pricey [source: Brune ].
