BioFuels Bacon Academy Science & Alternative Energy
Key Vocabulary Words • Fermenting: The process of changing carbohydrates into alcohol • Carbohydrates: Simple sugars • Blending: The combination of 2 or more liquids.
What Are BioFuels? • BioFuels are any type of biomass that is converted into a liquid form.
What is used to make BioFuels? • Corn • Sugar Cane • Old fryer grease
What Are BioFuels Used For? • Heating • Transportation
Popular Types of BioFuels • Ethanol: When carbohydrates in plant matter are fermented (much like brewing beer) into an “alcohol-like” liquid. • BioDiesel: The mixing of alcohol with animal fats or vegetable oil
Stand- Alone Fuel Source? • Both ethanol and BioDiesel are often not stand alone fuels. • Both are blended with other traditional fossil fuels • Ethanol is typically blended with gasoline • Biodiesel is often blended with diesel
Blending Identification • B20 is 20% BioDiesel and 80% traditional diesel fuel • E85 would be 85% ethanol and 15% traditional gasoline
So What’s the Point of BioFuels If We Still Rely on Traditional Fuels? • Blending lessens the amount of traditional fuel (gasoline and diesel) use. • Often biofuels are derived from recycled matter like wood chips, grass clippings or old fryer grease.
Fuel vs Food Debate • Crops like corn and sugar are grown for food. • Farms are selling traditional food to energy companies because they can sell their crops at a higher price. These foods are being turned into fuels. • Is it fair to grow foods for fuel when food prices are high and there are many populations in the world suffering from starvation?
