What Kinds of Fuels Do We Use In Our Vehicles Today?
2 Main Types:Gasoline
Cars, Small Trucks, Some Lawn Equipment & Tractors, Small Boats
Diesel Fuel Cars, Medium & Large Trucks, School Buses, Large Boats & Ships, Tractors & Farm Equipment
Problems With These Fuels…Gasoline and diesel fuel are made from
petroleum (oil) which is a finite resource Eventually we will run out of oil reserves and it takes thousands of years to create more
We have to import these fuels from unstable parts of the world
Makes fuel prices go up when supply is threatened
Gas and diesel exhaust cause pollution and Greenhouse Gases that may contribute to Global Warming
Rethinking Energy Sources…Use Less Energy Use Alternative
Forms of EnergyBiodiesel EthanolHydrogen / Fuel CellHybrid ElectricSolar PowerWind Power
One of the Best Solutions Comes from Plants –
Biodiesel!
Biodiesel Raw Materials
Oil or Fat AlcoholSoybean MethanolCorn EthanolCanolaCottonseed CatalystSunflowerSafflower Sodium hydroxideBeef tallow Potassium hydroxideUsed cooking oils
Biodiesel Reaction
Vegetable Oil or
Animal Fat (100 lbs.)
+Methanol or
Ethanol(10 lbs.)
Biodiesel(100 lbs.)
+Glycerine(10 lbs.)
In the presence of a catalyst

Uses for BiodieselBiodiesel can be used in any diesel engine
with little or no modifications.
Benefits of Biodiesel
78% Life Cycle Decrease In CO2
Energy Balance 4.6 to 1Diesel Engines are 30%
More Efficient Than Gasoline Engines –
You can drive 30% farther on a gallon of diesel than you can on a gallon of gas
Benefits of Biodiesel
Creates Jobs Increases Domestic Fuel
Production CapacityReduces Energy Imports
and Dependence on Foreign Oil Sources
Distributes our Energy Supply Across the Whole United States
Biodiesel Production Locations
Represent ~ 80% of biodiesel production volume in U.S.
Other Benefits of BiodieselEasy to Use Better for human healthLess “smelly” than diesel fuel –
biodiesel smells like french fries! Helps our American FarmersSustainable & renewable
