2 What is Biofuel?Biofuel is a fuel that is made from biomass (plant material). Biofuel is being heavily researched and refined as it emits significantly less carbon dioxide than fossil fuels.
3 Types of Biofuel - Ethanol Ethanol (ethyl alcohol) is produced from plants and plant waste, most commonly from sugarcane, corn, and switchgrass. A small amount exists in today’s gasoline to limit emissions released from automobile exhaust systems.
4 Types of Biofuel - Biodiesel This is a diesel-type fluid that is from vegetable oil extracted from soybeans, rapeseeds, sun flowers, oil palms, and jatropha shrubs. Fuel can also be processed from vegetable oils from restaurants.
5 Advantages and Disadvantages? Reduced CO2 emissions for some cropsMed. Net energy yield for biodiesel from oil palmsMed. Net energy yield for ethanol from sugar caneFuel crops can compete w/ food crops for land & raise food pricesFuel crops cam be invasive speciesLow net energy yield from ethanol and biodiesel from soybeansHigher CO2 emissions from corn ethanol
