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

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
