Biofuels
  • Biofuels- obtained from biological matter.
  • 80 renewable
  • Example of biofuels vegetable oil, biodiesel,
    bioalcohols, bioethers, and biogas

3
Goal of Biofuels
  • The main goal of using biofuels is to replace
    fossil fuels.
  • Reduce pollution of CO2 emissions

Making a Difference
  • Reduces smog by 50
  • 78 less carbon dioxide emissions
  • 8 less sulfur oxide
  • Lowers asthma and other lung disorders

How does biofuel work?
  • Sustainable renewable resources abundant and
    available in the United States
  • Made from plant oils, animal fats, and even
    recycled grease
  • Works in conventional diesel engines

7
Political/economical obstacles
  • Cost of production is higher than petroleum
  • No assured market for by-products of biofuel
    production
  • Production requires a license
  • Increased food prices
  • Increased hunger, and rural unemployment
  • Destruction of cultures of rural communities

8
Negative environmental impacts
  • Increases the use of fertilizers and pesticides
  • Requires large scale monocultures of trees,
    sugarcane, corn, oilpalm, soy and other crops
  • Destruction of watersheds and pollution of
    rivers, lakes, and streams
  • The use of GMOs is risky
