Biofuels pro’s:
· Ethanol Can be used as a fuel by itself or can be an additive to gasoline
· Waste wood from the timber industry can be used to create biofuel
· Is a renewable resource because the source (corn, sugar, fermentation) can be grown relatively quickly
· Biodiesel can be made at home
o Diesel fuel can be used for diesel engines
· Algae is an experimental biofuel that in theory could produce 5,000 gallons of biofuel an acre each year while absorbing carbon dioxide
· Grasses grown for befoul do not require much care which minimizes the need for fertilization and tractors
· Biofuel is cheap relatively
o Corn costs $1.09 per gallon to produce
o Sugarcane biofuel costs $0.87 per gallon to produce
· Biofuel has a good energy return ratio (input/output)
o Cellulose energy ratio between ½-1/36
o Corn energy ratio 1/1.3
o Sugarcane ratio 1/8
o Biodiesel ratio 1/2.5


Biofuel cons
· It would take 60% of the current crops to supply just 5% of the current demand for oil
· Inflation of food would rise food prices as more and more farmers would convert their land to meet the demand of energy and oil
· Almost the rest of the forest land would need to be converted into farmland in the world just to meet the needs of the world for energy
· It takes more energy to make ethanol than it actually puts out
· Not enough liquid ethanol pumps to replace the demand over night
· The burning of materials to produce biofuels would release enough nitrous oxide to generate the greenhouse effect
· Takes 450 lbs of corn to fill up a 25-gallon tank with ethanol. That is enough calories to feed a person for a yr
· Biofuels do not work well in extreme cold causing a limit on vehicle transportation
